Quantum Phases and Correlations Drive the Dynamics of Macroscopic Quantum Tunneling Escape in Quantum Simulators
Diego A. Alcala, Marie A. McLain, Lincoln D. Carr
Quantum tunneling remains unexplored in many regimes of many-body quantum physics, including the effect of quantum phase transitions on tunneling dynamics. In general, the quantum…
Quantum phase transition modulation in an atomtronic Mott switch
Marie A. McLain, Lincoln D. Carr
Mott insulators provide stable quantum states and long coherence times to due to small number fluctuations, making them good candidates for quantum memory and atomic circuits. We p…
For high-precision bosonic Josephson junctions, many-body effects matter
Marie A. McLain, Diego A. Alcala, Lincoln D. Carr
Typical treatments of superconducting or superfluid Josephson junctions rely on mean-field or two-mode models; we explore many-body dynamics of an isolated, ultracold, Bose-gas lon…
Macroscopic Quantum Tunneling Escape of Bose-Einstein Condensates
Xinxin Zhao, Diego A. Alcala, Marie A. McLain +5
Recent experiments on macroscopic quantum tunneling reveal a non-exponential decay of the number of atoms trapped in a quasibound state behind a potential barrier. Through both exp…
Nonequilibrium quantum dynamics of partial symmetry breaking for ultracold bosons in an optical lattice ring trap
Xinxin Zhao, Marie A. McLain, J. Vijande +3
A vortex in a Bose-Einstein condensate on a ring undergoes quantum dynamics in response to a quantum quench in terms of partial symmetry breaking from a uniform lattice to a biperi…
