Quantum fidelity for degenerate groundstates in quantum phase transitions
Yao Heng Su, Bing-Quan Hu, Sheng-Hao Li +1
Spontaneous symmetry breaking mechanism in quantum phase transitions manifests the existence of degenerate groundstates in broken symmetry phases. To detect such degenerate grounds…

Non-local correlations in the Haldane phase for an XXZ spin-1 chain: A perspective from infinite matrix product state representation
Yao Heng Su, Sam Young Cho, Bo Li +2
String correlations are investigated in an infinite-size XXZ spin-1 chain. By using the infinite matrix product state representation, we calculate a long-range string order. In the…
