Ramsey interferometry of non-Hermitian quantum impurities
F. Tonielli, N. Chakraborty, F. Grusdt +1
We introduce a Ramsey pulse scheme which extracts the non-Hermitian Hamiltonian associated to an arbitrary Lindblad dynamics. We propose a realted protocol to measure via interfero…

Topological Field Theory far from Equilibrium
Federico Tonielli, Jan Carl Budich, Alexander Altland +1
The observable properties of topological quantum matter are often described by topological field theories. We here demonstrate that this principle extends beyond thermal equilibriu…

Orthogonality catastrophe in dissipative quantum many body systems
F. Tonielli, R. Fazio, S. Diehl +1
We present an analog of the phenomenon of orthogonality catastrophe in quantum many body systems subject to a local dissipative impurity. We show that the fidelity , giving a…
