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…
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…
Realizing a spatially correlated lattice interferometer
Peng Peng, Dekai Mao, Yi Liang +4
Atom interferometers provide a powerful tool for measuring physical constants and testifying fundamental physics with unprecedented precision. Conventional atom interferometry focu…
