Universal scaling of many-body effects in quantum tunneling
Hongmian Shui, Chi-Kin Lai, Chengyang Wu +6
Quantum tunneling is fundamental to diverse phenomena and underpins a wide range of modern technologies. In the study of superconducting quantum computation and high-temperature su…
Two-mode collapse and revival of quantum coherent state in a tilted optical lattice
Chi-Kin Lai, Shengjie Jin, Yuanzhe Hu +6
Collective dynamics is an important out-of-equilibrium feature of quantum coherent states and usually reflects the intrinsic properties of the state. Collapse and revival (CR) dyna…
Probing universal phase diagram of dimensional crossover with an atomic quantum simulator
Jinyuan Tian, Zhongcheng Yu, Jing Liu +7
Dimensionality is a fundamental concept in physics, which plays a hidden but crucial role in various domains, including condensed matter physics, relativity and string theory, stat…
Scattering halos in strongly interacting Feshbach molecular Bose-Einstein condensates
Yuying Chen, Zhengxi Zhang, Chi-Kin Lai +5
We investigate the scattering halos resulting from collisions between discrete momentum components in the time-of-flight expansion of interaction-tunable molecular Bos…
Collisional scattering of strongly interacting D-band Feshbach molecules in optical lattices
Fansu Wei, Chi-Kin Lai, Yuying Chen +5
The excited bands in optical lattices manifest an important tool for studying quantum simulation and many-body physics, making it crucial to measure high-band scattering dynamics u…
