Mixed-state fidelity and quantum criticality at finite temperature
Paolo Zanardi, H. T. Quan, Xiaoguang Wang +1
We extend to finite temperature the fidelity approach to quantum phase transitions (QPTs). This is done by resorting to the notion of mixed-state fidelity that allows one to compar…

Quantum Thermodynamic Cycles and quantum heat engines
H. T. Quan, Yu-xi Liu, C. P. Sun +1
In order to describe quantum heat engines, here we systematically study isothermal and isochoric processes for quantum thermodynamic cycles. Based on these results the quantum vers…

Universal role of correlation entropy in critical phenomena
Shi-Jian Gu, Chang-Pu Sun, Hai-Qing Lin
In statistical physics, if we successively divide an equilibrium system into two parts, we will face a situation that, within a certain length , the physics of a subsystem is no…
