Fidelity susceptibility as a diagnostic of the commensurate-incommensurate transition: A revisit of the programmable Rydberg chain
Xue-Jia Yu, Sheng Yang, Jinbo Xu +1
In recent years, programmable Rydberg-atom arrays have been widely used to simulate new quantum phases and phase transitions, generating great interest among theorists and experime…
Quantum evolution speed in the finite-temperature bosonic environment
Jun-Qing Cheng, Guo-Qing Zhang, Jing-Bo Xu
We investigate the quantum evolution speed of a qubit in two kinds of finite-temperature environments. The first environment is a bosonic bath with Ohmic-like spectrum. It is found…
Multipartite entanglement, quantum coherence, and quantum criticality in triangular and Sierpiński fractal lattices
Jun-Qing Cheng, Jing-Bo Xu
We investigate the quantum phase transitions of the transverse-field quantum Ising model on the triangular lattice and Sierpiński fractal lattices by employing multipartite entangl…
Renormalization of trace distance and multipartite entanglement close to the quantum phase transitions of one- and two-dimensional spin-chain systems
Wei Wu, Jing-Bo Xu
We investigate the quantum phase transitions of spin systems in one and two dimensions by employing trace distance and multipartite entanglement along with real-space quantum renor…
Quantum phase transition by employing trace distance along with the density matrix renormalization group
Da-Wei Luo, Jing-Bo Xu
We use an alternative method to investigate the quantum criticality at zero and finite temperature using trace distance along with the density matrix renormalization group. It is s…
Trace distance and scaling behavior of coupled cavity lattice at finite temperature
Da-Wei Luo, Jing-Bo Xu
We use an alternative approach to study the quantum phase transition in a coupled cavity lattice at finite temperature. As an illustrative example, we investigate the behaviors of…
