Pure classical correlation dominant quantum thermal diode via three triangular-coupled qubits
Yi-jia Yang, Yu-qiang Liu, Chang-shui Yu
A quantum thermal diode is designed based on three pairwise coupled qubits, two connected to a common reservoir and the other to an independent reservoir. It is found that the inte…

Release of virtual photon and phonon pairs from qubit-plasmon-phonon ultrastrong coupling system
Ting-ting Ma, Yu-qiang Liu, Chang-shui Yu
The most important difference between ultrastrong and non-ultrastrong coupling regimes is that the ground state contains excitations. We consider a qubit-plasmon-phonon ultrastrong…
