Quantum fluctuation induced ordered phase in the Blume-Capel model
Norikazu Todoroki, Seiji Miyashita
We consider the Blume-Capel model with the quantum tunneling between the excited states. We find a magnetically ordered phase transition induced by quantum fluctuation in a model.…

Quantum Fluctuation-Induced Phase Transition in S=1/2 XY-like Heisenberg Antiferromagnets on the Triangular Lattice
Shin-ichiro Yoshikawa, Kouichi Okunishi, Makoto Senda +1
The selection of the ground state among nearly degenerate states due to quantum fluctuations is studied for the S=1/2 XY-like Heisenberg antiferromagnets on the triangular lattice…
