Legendre transformations and the thermodynamic geometry of 5D black holes

Yi-Wen Han, Gang Chen, Ming-Jian Lan

This paper studies the thermodynamic properties of the 5D black hole in Einstein-Gauss-Bonnet gravity from the viewpoint of geometrothermodynamics. It {is found} that the Legendre…

Thermodynamics, geometrothermodynamics and critical behavior of (2+1)-dimensional black holes

YiWen Han, Gang Chen

In this paper, we study the properties of the (2+1)-dimensional black holes from the viewpoint of geometrothermodynamics. We show that the Legendre invariant metric of the (2+1)-di…

Geometric phase in the Kitaev honeycomb model and scaling behavior at critical points

Jinling Lian, J. -Q. Liang, Gang Chen

In this paper a geometric phase of the Kitaev honeycomb model is derived and proposed to characterize the topological quantum phase transition. The simultaneous rotation of two spi…

Topological degeneracy and decoherence-protected qubits in circuit QED

Gang Chen, Zheng-Yuan Xue, J. -Q. Liang

We introduce an extended Dicke model with controllable long-range atom-atom interaction to simulate topologically ordered states and achieve decoherence-protected qubits. We illust…

Exotic quantum phase transitions in a Bose-Einstein condensate coupled to an optical cavity

Gang Chen, Xiaoguang Wang, J. -Q. Liang +1

A new extended Dicke model, which includes atom-atom interactions and a driving classical laser field, is established for a Bose-Einstein condensate inside an ultrahigh-finesse opt…

Ground-State Properties for Coupled Bose-Einstein Condensates inside a Cavity Quantum Electrodynamics

Gang Chen, Zidong Chen, J. -Q. Liang

We analytically investigate the ground-state properties of two-component Bose-Einstein condensates with few ⁸⁷Rb atoms inside a high-quality cavity quantum electrodynam…
