Grassmann time-evolving matrix product operators for fermionic impurities coupled to a superconducting bath
Chu Guo, Wei Wu, Xiansong Xu +4
The Grassmann time-evolving matrix product operator (GTEMPO) method, which represents the Feynman-Vernon influence functional as a temporal matrix product state, has been shown to…
Time-evolving matrix product operators for off-diagonal system-bath coupling
Chu Guo, Wei Wu, Xiansong Xu +3
The time-evolving matrix product operator (TEMPO) method has proven to be a powerful method to study the long-time dynamics of bosonic impurity problems where a small system is lin…
Stark-induced tunable phase transition in the two-photon Dicke-Stark model
Cui-Lu Zhai, Wei Wu, Chun-Wang Wu +1
We theoretically investigate the superradiant phase transition (SPT) in the two-photon Dicke-Stark model, which incorporates both Rabi and Stark coupling. By introducing a Stark co…
Thermometry of Trapped Ions Based on Bichromatic Driving
Xie-Qian Li, Yi Tao, Ting Chen +4
Accurate thermometry of laser-cooled ions is crucial for the performance of the trapped-ions quantum computing platform. However, most existing methods face a computational exponen…
PT-symmetric quantum sensing: advantages and restrictions
Yan-Yi Wang, Chun-Wang Wu, Wei Wu +1
Quantum sensing utilizing unique quantum properties of non-Hermitian systems to realize ultra-precision measurements has been attracting increasing attention. However, the debate o…
Experimental violation of Leggett-Garg inequality in a three-level trapped-ion system
Tianxiang Zhan, Chunwang Wu, Manchao Zhang +9
Leggett-Garg inequality (LGI) studies the temporal correlation in the evolution of physical systems. Classical systems obey the LGI but quantum systems may violate it. The extent o…
