Quantum entanglement entropy and Tomonaga-Luttinger liquid to liquid transition in biquadratic spin-1 XY chain with rhombic single-ion anisotropy
Yan-Wei Dai, Yao Heng Su, Sam Young Cho +1
Quantum phase transitions (QPTs) are investigated in biquadratic spin- XY chain with rhombic single-ion anisotropy by using the ground state energy (GE), the bipartite entanglem…
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…
Tensor network states for quantum spin ladders
Sheng-Hao Li, Yao-Heng Su, Yan-Wei Dai +1
We have developed an efficient tensor network algorithm for spin ladders, which generates ground-state wave functions for infinite-size quantum spin ladders. The algorithm is able…
Is the Fano Antiresonance a Necessary Requirement for Circulating Currents in Mesoscopic Interferometers?
Yao Heng Su, Sam Young Cho, Ai Min Chen
Coherent quantum tunneling effects on quantum interference are investigated in electron transport through a mesoscopic interferometer. An evanescent wave tunneling through a potent…
