Observation of quantum multi-Mpemba effect in a trapped-ion system
Gang Xia, Yu-Jie Zheng, Jing Huang +9
The quantum Mpemba effect (ME) in Markovian systems is conventionally explained by a smaller overlap between the initial state and the slowest decay mode (SDM). Such state, initial…
Confined non-Hermitian skin effect in a semi-infinite Fock-state lattice
Zhi Jiao Deng, Xing Yao Mi, Ruo Kun Cai +2
In this paper, we investigate the non-Hermitian skin effect in a semi-infinite Fock-state lattice, where the inherent coupling scales as \sqrt{n}. By analytically solving a non-uni…
A Solvable Semi-infinite Fock-state-lattice SSH Model: the Stable Topological Zero Mode and the Non-Hermitian Bound Effect
Xing Yao Mi, Yong-Chun Liu, Zhi Jiao Deng +2
Fock-state lattice (FSL) offers a powerful quantum simulator for topological phenomena due to the unbounded scalability and ease of implementation. Nevertheless, the unique topolog…
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…
Estimation of the Laser Frequency Nosie Spectrum by Continuous Dynamical Decoupling
Manchao Zhang, Yi Xie, Jie Zhang +5
Decoherence induced by the laser frequency noise is one of the most important obstacles in the quantum information processing. In order to suppress this decoherence, the noise powe…
Weak-to-strong transition of quantum measurement in a trapped-ion system
Yiming Pan, Jie Zhang, Eliahu Cohen +3
Quantum measurement remains a puzzle through its stormy history from the birth of quantum mechanics to state-of-the-art quantum technologies. Two complementary measurement schemes…
