The quantum Mpemba effect in symmetric random Clifford circuits
Shion Yamashika, Filiberto Ares, Pasquale Calabrese
The quantum Mpemba effect is the counterintuitive phenomenon whereby a quantum state initially farther from equilibrium relaxes faster than one initially closer to it. We demonstra…
Entanglement asymmetry and quantum Mpemba effect for Kramers-Wannier duality
Milo Vescovo, Pasquale Calabrese, Filiberto Ares
The Kramers-Wannier duality is the prototypical example of a non-invertible symmetry, yet little is known about its fate away from criticality and out of equilibrium. We introduce…
Universality of Measurement-Induced Criticality under Symmetry-Breaking Measurements
Angelo Russotto, Filiberto Ares, Pasquale Calabrese
We study the critical properties of random quantum circuits with a symmetry subject to local projective measurements that explicitly break this symmetry. We find that, at th…
Boundary quenches in (1+1)-dimensional conformal field theory
Michele Fossati, Colin Rylands, Eytan Grosfeld +2
We investigate a class of local quantum quenches in which the conformal boundary condition of a (1+1)-dimensional conformal field theory is abruptly changed. We derive a remarkably…
Entanglement Hamiltonians in dissipative free fermions and the time-dependent GGE
Riccardo Travaglino, Federico Rottoli, Pasquale Calabrese
We investigate the dynamics of Entanglement Hamiltonians (EHs) in dissipative free-fermionic systems using a recent operator-based formulation of the quasiparticle picture. Focusin…
Inhomogeneous quenches and GHD in the QSSEP model
Angelo Russotto, Filiberto Ares, Pasquale Calabrese +1
We investigate the dynamics of the Quantum Symmetric Simple Exclusion Process starting from spatially inhomogeneous initial states. This one-dimensional system of free fermio…
Entanglement evolution from entangled multipodal states
Konstantinos Chalas, Pasquale Calabrese, Colin Rylands
In a periodic lattice system an entangled antipodal pair state, otherwise known as a crosscap state, is a simple two site product state in which spins at antipodal sites are prepar…
Dynamics of entanglement fluctuations and quantum Mpemba effect in the QSSEP model
Angelo Russotto, Filiberto Ares, Pasquale Calabrese +1
We study the out-of-equilibrium dynamics of entanglement fluctuations in the Quantum Symmetric Simple Exclusion Process, a free-fermion chain with hopping amplitudes that are…
A simpler probe of the quantum Mpemba effect in closed systems
Filiberto Ares, Colin Rylands, Pasquale Calabrese
We study the local relaxation of closed quantum systems through the relative entropy between the reduced density matrix and its long time limit. We show, using analytic arguments c…
The quantum Mpemba effects
Filiberto Ares, Pasquale Calabrese, Sara Murciano
The Mpemba effect, where a hotter system can equilibrate faster than a cooler one, has long been a subject of fascination in classical physics. In the past few years, significant t…
Entanglement asymmetry dynamics in random quantum circuits
Filiberto Ares, Sara Murciano, Pasquale Calabrese +1
We study the dynamics of entanglement asymmetry in random unitary circuits (RUCs). Focusing on a local charge, we consider symmetric initial states evolved by both local one…
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…
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…
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…

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…

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…
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…
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…

Shion Yamashika, Filiberto Ares, Pasquale Calabrese
We study the time evolution of the Rényi entanglement entropies following a quantum quench in a two-dimensional (2D) free-fermion system. By employing dimensional reduction, we eff…
Entanglement asymmetry and quantum Mpemba effect in the XY spin chain

Entanglement asymmetry is a quantity recently introduced to measure how much a symmetry is broken in a part of an extended quantum system. It has been employed to analyze the non-e…
Microscopic origin of the quantum Mpemba effect in integrable systems
Colin Rylands, Katja Klobas, Filiberto Ares +3
The highly complicated nature of far from equilibrium systems can lead to a complete breakdown of the physical intuition developed in equilibrium. A famous example of this is the M…
More on symmetry resolved operator entanglement
Sara Murciano, Jérôme Dubail, Pasquale Calabrese
The `operator entanglement' of a quantum operator is a useful indicator of its complexity, and, in one-dimension, of its approximability by matrix product operators. Here we fo…
