Impurity-induced quantum phase transition in finite Heisenberg spin chains: Criteria for existence and stability
Gang Chen, Yunxuan Li, Zheyong Fan +1
A quantum phase transition may occur in a system at zero temperature when a controlling parameter is tuned towards a critical point. An important question is whether such a critica…

Zeroth Order Phase Transition in a Holographic Superconductor with Single Impurity
Hua Bi Zeng, Hai-Qing Zhang
We investigate the single normal impurity effect in a superconductor by the holographic method. When the size of impurity is much smaller than the host superconductor, we can repro…

Holographic superconductors from the massive gravity
Hua Bi Zeng, Jian-Pin Wu
A holographic superconductor is constructed in the background of a massive gravity theory. In the normal state without condensation, the conductivity exhibits a Drude peak that app…
