Smearing of dynamical quantum phase transitions in dissipative free-fermion systems
Gilles Parez, Vincenzo Alba
We investigate the Lindblad dynamics of the reduced Loschmidt echo (RLE) in dissipative quadratic fermion systems. Focusing on the case of gain and loss dissipation, we derive gene…
Reduced fidelities for free fermions out of equilibrium: From dynamical quantum phase transitions to Mpemba effect
Gilles Parez, Vincenzo Alba
We investigate the out-of-equilibrium dynamics after a quantum quench of the reduced fidelities between the states of a subregion at different times. Precisely, we consider the…
Analytical results for the entanglement dynamics of disjoint blocks in the XY spin chain
Gilles Parez, Riccarda Bonsignori
The study of the dynamics of entanglement measures after a quench has become a very active area of research in the last two decades, motivated by the development of experimental te…
Symmetry-resolved Rényi fidelities and quantum phase transitions
Gilles Parez
We introduce a family of quantum Rényi fidelities and discuss their symmetry resolution. We express the symmetry-resolved fidelities as Fourier transforms of charged fidelities, fo…
Dynamics of charge-imbalance-resolved entanglement negativity after a quench in a free-fermion model
Gilles Parez, Riccarda Bonsignori, Pasquale Calabrese
The presence of a global internal symmetry in a quantum many-body system is reflected in the fact that the entanglement between its subparts is endowed with an internal structure,…
Exact quench dynamics of symmetry resolved entanglement in a free fermion chain
Gilles Parez, Riccarda Bonsignori, Pasquale Calabrese
The study of the entanglement dynamics plays a fundamental role in understanding the behaviour of many-body quantum systems out of equilibrium. In the presence of a globally conser…
Quasiparticle dynamics of symmetry resolved entanglement after a quench: the examples of conformal field theories and free fermions
Gilles Parez, Riccarda Bonsignori, Pasquale Calabrese
The time evolution of the entanglement entropy is a key concept to understand the structure of a non-equilibrium quantum state. In a large class of models, such evolution can be un…
