Many-Body Dephasing in a Trapped-Ion Quantum Simulator
Many-Body Dephasing in a Trapped-Ion Quantum Simulator
How a closed interacting quantum many-body system relaxes and dephases as a function of time is a fundamental question in thermodynamic and statistical physics. In this Letter, we analyze and observe the persistent temporal fluctuations after a quantum quench of a tunable long-range interacting transverse-field Ising Hamiltonian realized with a …
