Memory effect for interaction driven quantum gas

Phys. Rev. A 96, 033628 (2017), also in arXiv:1706.00441
Quantifying memory effect in a quantum system is not trivial. Although most of the quantum system exhibit memory effect, it does not emerge in every physical observable. Here, in 1D interacting Fermi and Bose gas, the steady state current show memory effect under an interaction quench on half of the system.
