Energy dynamics in a generalized compass chain
Yu-Cheng Qiu, Qing-Qiu Wu, Wen-Long You
We investigate the energy dynamics in a generalized compass chain under an external magnetic field. We show that the energy current operators act on three contiguous sites in the a…

Quantum phase transitions in a generalized compass chain with three-site interactions
Wen-Long You, Yu-Cheng Qiu, Andrzej M. Oleś
We consider a class of one-dimensional compass models with XYZYZX-type of three-site exchange interaction in an external magnetic field. We present the exact solution derived by…
