Ramsey interferometry of non-Hermitian quantum impurities

Year: 2020

Type: article

Abstract: The authors introduce a Ramsey pulse scheme which allows to probe the Loschmidt echo of non-Hermitian Hamiltonians. They study a model of an impurity atom which is dissipatively coupled to a surrounding Bose gas and identify a many-body quantum Zeno effect in the corresponding non-Hermitian Loschmidt echo.
