Universal construction of order parameters for translation-invariant quantum lattice systems with symmetry-breaking order
Jin-Hua Liu, Qian-Qian Shi, Hong-Lei Wang +2
For any translation-invariant quantum lattice system with a symmetry group G, we propose a practical and universal construction of order parameters which identify quantum phase tra…

Singularities in fidelity surfaces for quantum phase transitions: a geometric perspective
Huan-Qiang Zhou, Jian-Hui Zhao, Hong-Lei Wang +1
The fidelity per site between two ground states of a quantum lattice system corresponding to different values of the control parameter defines a surface embedded in a Euclidean spa…
