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…
Single-photon-driven high-order sideband transitions in an ultrastrongly coupled circuit quantum electrodynamics system
Zhen Chen, Yimin Wang, Tiefu Li +8
We report the experimental observation of high-order sideband transitions at the single-photon level in a quantum circuit system of a flux qubit ultrastrongly coupled to a coplanar…
Four-junction superconducting circuit
Yueyin Qiu, Wei Xiong, Xiao-Ling He +2
We develop a theory for the quantum circuit consisting of a superconducting loop interrupted by four Josephson junctions and pierced by a magnetic flux (either static or time-depen…
