The A-Cycle Problem for Transverse Ising Ring
Jian-Jun Dong, Peng Li, Qi-Hui Chen
Traditionally, the transverse Ising model is mapped to the fermionic c-cycle problem, which neglects the boundary effect due to thermodynamic limit. If persisting on a perfect peri…

Frustration-Induced Gaplessness in the Frustrated Transverse Ising Ring
Jian-Jun Dong, Peng Li, Qi-Hui Chen
New effects in the frustrated transverse Ising ring are predicted. The system is solved based on a mapping of Pauli spin operators to the Jordan-Wigner fermions. We group the low-l…

Dimer XXZ Spin Ladders: Phase diagram and a Non-Trivial Antiferromagnetic Phase
Qi-Hui Chen, Long-Fei Guo, Peng Li
We study the dimer spin model on two-leg ladders with isotropic Heisenberg interactions on the rung and anisotropic interactions along the rail in an external field. Co…
