ABSTRACT:
We study the ground-state
information of one-dimensional Heisenberg chain with alternating D-term. Given the ground-state phase diagram, the
ground-state energy and the entanglement entropy are obtained by tensor-net work algorithm. The phase
transition points are shown in the entanglement entropy figure. The results are
agreed with the phase diagram.
