Many-body multi-valuedness of particle-current variance in closed and open cold-atom systems
Mekena Metcalf, Chen-Yen Lai, Massimiliano Di Ventra +1
The quantum variance of an observable is a fundamental quantity in quantum mechanics, and the variance provides additional information other than the average itself. By examining t…
Quantification of the memory effect of steady-state currents from interaction-induced transport in quantum systems
Chen-Yen Lai, Chih-Chun Chien
Dynamics of a system in general depends on its initial state and how the system is driven, but in many-body systems the memory is usually averaged out during evolution. Here, inter…
Protocols for dynamically probing topological edge states and dimerization with fermionic atoms in optical potentials
Mekena Metcalf, Chen-Yen Lai, Kevin Wright +1
Topological behavior has been observed in quantum systems including ultracold atoms. However, background harmonic traps for cold-atoms hinder direct detection of topological edge s…
Challenges and constraints of dynamically emerged source and sink in atomtronic circuits: From closed-system to open-system approaches
Chen-Yen Lai, Chih-Chun Chien
While batteries offer electronic source and sink in electronic devices, atomic analogues of source and sink and their theoretical descriptions have been a challenge in cold-atom sy…
Hysteresis of noninteracting and spin-orbit coupled atomic Fermi gases with relaxation
Mekena Metcalf, Chen-Yen Lai, Chih-Chun Chien
Hysteresis can be found in driven many-body systems such as magnets and superfluids. Rate-dependent hysteresis arises when a system is driven periodically while relaxing towards eq…
Geometry-induced memory effects in isolated quantum systems: Observations and applications
Chen-Yen Lai, Chih-Chun Chien
Memory effects can lead to history-dependent behavior of a system, and they are ubiquitous in our daily life and have broad applications. Here we explore possibilities of generatin…
