ABSTRACT
In this work, a generalized Davydov soliton field (DSF) has been investigated. The characteristics of correlation and
information for the filed are emphasized and studied. It is a sort of correlation among so called generalized solitons so
that the field may appear to some macroscopic quantum properties such as the superconductivity at room temperature.
Secondly, the character of information for the field can be described by a nonlinear Liouville equation in the quantum
information representation. This provides a basis to express information quality of DSF, which means that DSF can
influence or drive object by using (soliton type of) quantum information density. All these two aspects provide a foun-
dation which possibly explains many potential biological functions of human body such as some complex bio-electro-
magnetic phenomena and their interactions with objects.
Keywords: Soliton; Nonlinear Interaction; Biological Field; Quantum Information; Coherence
1. Introduction
For many years, the bio-photonics experiments have
discovered that the complex human body likes a set of
many molecules and atoms to have particle type of dis-
crete characteristic frequency as a stably entire body. This
symbolizes human body to have distinctive quantum ex-
citation field. Not only that, the human body in various
function status experiments often be measured with visi-
ble color light and a variety of electromagnetic waves as
well as acoustic wave phenomena [1-7].
Some scholars from the physical point of view to ex-
plore this kind of phenomena, and think the characteristic
frequency existence due to nonlinear interaction within
the system units continuously exchange energy between
body and environment, which results in the coherent ex-
citation of organisms with long-range correlations. This
means the coherence can be achieved by nonlinear inter-
action in organism internal subunits. Thereby they put
forward entire concepts about human quantization of
dissipative structure in self-organization [8-14].
In fact in early 1973 Davydov proposed protein mole-
cules excited “solitary” model of the energy transport.
According to this theory, the protein molecule three spiral
micro-vibration and lattice distortion of amide-I exciton
interactions produce collective excitations as formed
soliton, along the helix propagation, so that ATP mole-
cules hydrolyzed to produce energy from one place to
another place. It is found in the experiment (3 - 7) × 1010
Hz field frequency that soliton resonance light decompose
into excitons and local deformation, corresponding to a
new band in 1650 cm1, with amide-I exciton infrared
absorption spectra observed on the 1666 cm1 line. This
proves that there is a red shift of 16 cm1 corresponding to
the formation of just soliton bound energy. This shows the
new metabolism possibilities in the presence of excitons
and phonon interaction as well collective excitation of
coherence. However, Davydov soliton in the presence of
short duration is serious obstacle to explain it as a basic
information transmission unit. After that, Pang Xiaofeng
improved and developed Davydov soliton model, and
established a frame of biological soliton transmission
theory based on his nonlinear quantum theory [15,16].
The above phenomena and explorations demonstrate
that the human body is a quantum field system. This
quantum field has complex nonlinear elicitors, biological
solitons, and its main interaction may be related to
bio-electromagnetic field, which is manifested by the
presence of sensitive absorption and emission character-
istic frequency and complex spectrum. This is the starting
point for further research.
2. Physical Model
Let us start from the Davydov soliton perspective and
extend the Pang Xiaofeng introduced concepts about the

domain and the human body biological field to DSF. We
can take DSF as a dissipative structure of non-equilibrium
thermodynamic system. This DSF system consists of
generalized solitons or generalized nonlinear excitations,
which represents a local oscillation with characteristics of
quasi particles and can transmit from a quantum energy
level to other quantum energy level. We extend the theo-
retical model of the domain, and believe that a domain is a
generalized nonlinear excitation or generalized soliton,
the most important interaction is with the electromagnetic
field, and in addition the generalized soliton is through the
exchange of virtual bosons (e.g. virtual phonon or virtual
photon) to form the non-local correlation. It is this corre-
lation role that can cause entire cooperation of DSF, thus
illustrate a macroscopic quantum effect of DSF under the
condition of the correlation strength and correlation dis-
tance increase.
Consider a strongly correlated situation, then between
generalized solitons (may also include a finite object
interacted with DSF) there exist exchange of virtual pho-
non or virtual photon. This forms a harmoniously entire
biological field correlation or orderly self-organization
whose wave function is quantized as an operator
.
Although the human body system is considered as an open
dissipative structure of non-equilibrium thermodynamic
system, but if adding the correlation part caused by in-
teraction with the system, then the system can be seen as a
total equilibrium system. Thus, according to the second
law of thermodynamics, the free energy density tends to
minimum.
Local generalized soliton density is square modulus of
field operator 2
, where
can be defined as an order
parameter, where 0
0 as disordered situation,
as orderly condition. When DSF forms disorderly to or-
derly transition, in near the transformation point
should be small, thus the free energy density

Now let one consider two adjacent domains to form

A higher order of correlation also is possible. It is these

for the soliton equation proposed by Pang Xiaofeng at
ATP hydrolysis in helix proteins producing collective
excitations [15-17]. Hence, this equation can be defined as
a basic equation describing DSF in highly correlated
states. In considering the human field high order coherent
conditions, higher order of extension of this equation is
also possible, in that situation the solution is usually as-
sociated with multiple well potentials.

Thus the introduction as order parameter =
biological field. The order parameter (field operator)
composes of DSF which describes cooperative
behaviors of many particles as an entirety; therefore it is
called as macroscopic wave function or order parameter
based on the Landau second type of phase transition the-
ory [18]. This highly ordered biological field can be fur-
ther integrated with only one field function expression
and keep step with consistent with overall vibration to
show macroscopic quantum effect that can be seen as an
origin of many human biological function or potential
special features of nonlinear quantum mechanics.
In short, biological DSF systems rely on the non-linear
interactions among internal sub-units and the energy ex-
change process of self-organization with environment to
maintain their order and perfect ceaselessly, and form its
own characteristic frequency. These presences of multiple
biological elicitor and soliton may be key mechanism to
support a variety of special features of the human body
functions. These biological elicitor and soliton in the body
cycle tracks are probably so called acupuncture channels.

There is clearly to show these ground state changes
have the symmetry broken, which has consistency same
as the situation of electro-acoustic superconductor system.
In fact in the electro-acoustic superconductors, when
the electrons in the two equivalent ground states, the
above two energy minima are just ground states of the
super-conductor because the electron and virtual phonon
nonlinear interactions prevent electron energy dispersion
and thereby form a stable superconducting electronic—
Cooper pair. The corresponding energy represents as
2rr


, which is just a binding energy for the elec-
tronic bound of the Bose-Cooper pair. So this Cooper pair
is not else, but a kind of soliton. Hence the supercon-
ducting electrons are also to form a kind of solitons. Pang
Xiaofeng has pointed out this in [17].
We want to emphasize here the above similarity be-
tween the theoretical model of superconductivity and the
correlation model of DSF. Superconducting critical tem-
perature can be obtained by considering the soliton for-
mula, the finite temperature gap equation and the quasi-
Fermi particle distribution [19],

where
0g is the density of states. The key is the
nonlinear coupling coefficient
in the nonlinear inter-
action 4

of Equation (4). If
becomes bigger,
superconducting transition temperature increases. It is
precisely
influencing the correlation strength en-
hancement, so that the superconducting transition tem-
perature is increased. This demonstrates that the super-
conductivity for DSF model even at room temperature is
possible.
But the high temperature superconducting mechanism
and theory has not finally been settled, and the room tem-
perature superconductor effect either experimentally or
theoretically is very thorny problem. Moreover, the hy-
pothesis as superconductive electrons form a solitary is
also required to confirm in relevant experiments of high
temperature superconductor. Also from experimental
perspective, human superconducting phenomenon has not
been found, and some experiments only discovered that
the acupuncture channels resistance is smaller than other
direction resistor. Whether or not there exist some special
functional states whose resistance closes to zero? This sort
of experiment needs to be investigated in future.
Thus, we suggest performing an experiment in which
DSF is applied to the appropriate materials to induce room
temperature superconductor. If this can be realized, then
in a considerable extent it demonstrates that our proposed
above generalized soliton field theory is a key mechanism
to explain many phenomena of the bio-electromagnetic
experiments, at the same time, also gives quit important
contribution for the high (room) temperature supercon-
ducting mechanism.

The above Equation (4) is for describing DSF in human

body, whose solution is a kind of generalized biological
soliton under certain conditions which can propagate over
distance without decaying inside or outside the human
body. These solitons are considered to be the basic units of
human biological information transmission. This intro-
duces a biological information problem in human body.
Further, DSF can also be generalized to a kind of bio-
logical information field. We can even consider what
information density equation to drive or control DSF and
produces some special physiological functions above the
threshold of energy information intensity, because in the
real world, there may exist effective interaction between
human body biological field and environment, such as a
variety of spectroscopy, magnetic spectrum radiation
treatment as a role of physiotherapy instrument for human
body [20,21].
Furthermore, for a classical system it can also be proved
that the classical Liouville equation can be written by [25].
Therefore, the description of the generalized soliton can
be extended into a concept of the generalized quantum
information density, since the corresponding nonlinear
Schrodinger equation stunned into generalized Liouville
equation given by

Here character of information for DSF may be de-
scribed by an information representation of the nonlinear
Liouville equation [22-25]. To explain clearly, we firstly
define a quantum information density as

According to the above point of view, more broadly,
whole world is composed of quantum information density
driven by energy, and all kinds of objects only presented
various information density distribution. Often this in-
formation distribution at different frequency, with various
waveform amplitudes, but by the driving from a type of
quantum soliton information density field, the target in-
formation distribution with different frequency and wave-
form amplitudes will tend to a synchronous resonance, so
that the target information density distribution become the
same distribution as the quantum soliton information
density field. The both become an entire form to possess
possibly macroscopic quantum effect to render many
specific potential functions of human body.

In brief, by considering the significance of
as a
minimum information density, generally speaking, the
new equation driving object information density ob
has a solitary type of solution, which provides certain
PQID to drive the quantum information density of object
to tend to a kind of resonance synchronous, so that the
both become highly coherent as information solitons with
a variety of macroscopic quantum effect. Extremely, it is
possible that the information wave (envelope) to around
the object form an entire soliton, so that the carrier of
waves in the solitons have resonance with each others as
a sort of strongly non-local correlations. This may make
the target atom or molecule separation, aggregation, dis-
placement and finally accompanied by the wave carrier
strength reaching a threshold, some macro-quantum ef-
fects (such as macro-quantum tunnelling, the room su-
perconductor phenomenon, etc.) can be shown as men-
tioned in previous description.
5. Conclusion
The coherence and information aspects for DSF theory
have been investigated. We firstly emphasize the correla-
tion characteristics of the filed. It is this sort of correla-
tion between so called generalized solitons, some mac-
roscopic quantum effects are possible such as the super-
conducting at room temperature. Secondly, a nonlinear
Liouville equation in the quantum information represen-
tation has been represented, which provides a basis to
describe information character of DSF. This means that
DSF can be influenced or driven by object using (soliton
type of) PQID. All these two elements provide a founda-
tion possibly to explain many potential functions of hu-
man body and relevant interactions with objects.
