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…
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…
Observation of quantum temporal correlations well beyond Luders bound
Chun-Wang Wu, Man-Chao Zhang, Yan-Li Zhou +10
Quantum correlations, both spatial and temporal, are the central pillars of quantum mechanics. Over the last two decades, a big breakthrough in quantum physics is its complex exten…
Phonon Number Measurement Using Optimal Composite Pulses
Xie-Qian Li, Chun-Wang Wu, Ping-Xing Chen
Measuring the phonon number of the laser-cooled ions is an indispensable step in evaluating whether an ion is in ground state. At present, commonly used methods in the experiments…
Observation of quantum strong Mpemba effect
Jie Zhang, Gang Xia, Chun-Wang Wu +10
An ancient and counterintuitive phenomenon know as the Mpemba effect (water can cool faster when initially heated up) showcases the critical role of initial conditions in relaxatio…
