Quench dynamics of entanglement from crosscap states
Konstantinos Chalas, Pasquale Calabrese, Colin Rylands
The linear growth of entanglement after a quench from a state with short-range correlations is a universal feature of many body dynamics. It has been shown to occur in integrable a…
On symmetry-resolved generalized entropies
Fei Yan, Sara Murciano, Pasquale Calabrese +1
Symmetry-resolved entanglement, capturing the refined structure of quantum entanglement in systems with global symmetries, has attracted a lot of attention recently. In this manusc…
Quasiparticle Picture for Entanglement Hamiltonians in Higher Dimensions
Riccardo Travaglino, Colin Rylands, Pasquale Calabrese
We employ the quasiparticle picture of entanglement evolution to obtain an effective description for the out-of-equilibrium Entanglement Hamiltonian at the hydrodynamical scale fol…
Entanglement asymmetry in CFT with boundary symmetry breaking
Michele Fossati, Colin Rylands, Pasquale Calabrese
We examine the behavior of the entanglement asymmetry in the ground state of a (1+1)-dimensional conformal field theory with a boundary condition that explicitly breaks a bulk symm…
Non-Abelian entanglement asymmetry in random states
Angelo Russotto, Filiberto Ares, Pasquale Calabrese
The entanglement asymmetry measures the extent to which a symmetry is broken within a subsystem of an extended quantum system. Here, we analyse this quantity in Haar random states…
Quenching from superfluid to free bosons in two dimensions: entanglement, symmetries, and quantum Mpemba effect
Shion Yamashika, Pasquale Calabrese, Filiberto Ares
We study the non-equilibrium dynamics of bosons in a two-dimensional optical lattice after a sudden quench from the superfluid phase to the free-boson regime. The initial superflui…
Dynamical symmetry restoration in the Heisenberg spin chain
Colin Rylands, Eric Vernier, Pasquale Calabrese
The entanglement asymmetry is an observable independent tool to investigate the relaxation of quantum many body systems through the restoration of an initially broken symmetry of t…
Entanglement asymmetry in the critical XXZ spin chain
Marco Lastres, Sara Murciano, Filiberto Ares +1
We study the explicit breaking of a symmetry to a subgroup employing the entanglement asymmetry, a recently introduced observable that measures how much symmetries a…
Non-equilibrium dynamics of charged dual-unitary circuits
Alessandro Foligno, Pasquale Calabrese, Bruno Bertini
The interplay between symmetries and entanglement in out-of-equilibrium quantum systems is currently at the centre of an intense multidisciplinary research effort. Here we introduc…
Entanglement Hamiltonians and the quasiparticle picture
Federico Rottoli, Colin Rylands, Pasquale Calabrese
The entanglement Hamiltonian (EH) provides the most comprehensive characterization of bipartite entanglement in many-body quantum systems. Ground states of local Hamiltonians inher…
Multiple crossing during dynamical symmetry restoration and implications for the quantum Mpemba effect
Konstantinos Chalas, Filiberto Ares, Colin Rylands +1
Local relaxation after a quench in 1-D quantum many-body systems is a well known and very active problem with rich phenomenology. Except for pathological cases, the local relaxatio…
Quantum Mpemba Effect in Random Circuits
Xhek Turkeshi, Pasquale Calabrese, Andrea De Luca
The essence of the Mpemba effect is that non-equilibrium systems may relax faster the further they are from their equilibrium configuration. In the quantum realm, this phenomenon a…
Entanglement asymmetry and quantum Mpemba effect in two-dimensional free-fermion systems
Shion Yamashika, Filiberto Ares, Pasquale Calabrese
The quantum Mpemba effect is the counter-intuitive non-equilibrium phenomenon wherein the dynamic restoration of a broken symmetry occurs more rapidly when the initial state exhibi…
Entanglement Hamiltonian in the non-Hermitian SSH model
Federico Rottoli, Michele Fossati, Pasquale Calabrese
Entanglement Hamiltonians provide the most comprehensive characterisation of entanglement in extended quantum systems. A key result in unitary quantum field theories is the Bisogna…
Entanglement asymmetry in CFT and its relation to non-topological defects
Michele Fossati, Filiberto Ares, Jerome Dubail +1
The entanglement asymmetry is an information based observable that quantifies the degree of symmetry breaking in a region of an extended quantum system. We investigate this measure…
Observing the quantum Mpemba effect in quantum simulations
Lata Kh Joshi, Johannes Franke, Aniket Rath +9
The non-equilibrium physics of many-body quantum systems harbors various unconventional phenomena. In this study, we experimentally investigate one of the most puzzling of these ph…
