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…
Asymmetry dynamics and nonequilibrium symmetry-breaking phase transitions
Liv Hammer, Colin Rylands, Federico Carollo
In classical settings, the Mpemba effect occurs when a hotter system cools faster than an initially colder one. In quantum systems, this effect can be reinterpreted exploiting the…
Initial State Memory in Finite Random Brickwork Circuits
Jakob Bannister, Katja Klobas, Colin Rylands +1
We ask under what conditions a finite brickwork circuit of random gates retains local information about the initial state. To answer this question we measure the averaged Frobenius…
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…
Quench dynamics of entanglement entropy under projective charge measurements: the free fermion case
Riccardo Travaglino, Colin Rylands, Pasquale Calabrese
We consider the effect of projective measurements on the quench dynamics of the bipartite entanglement entropy in one dimensional free fermionic systems. In our protocol, we consid…
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…
Quench dynamics of negativity Hamiltonians
Riccardo Travaglino, Colin Rylands, Pasquale Calabrese
In this paper, we investigate the quench dynamics of the negativity and fermionic negativity Hamiltonians in free fermionic systems. We do this by generalizing a recently developed…
Emergent boundary supersymmetry in a one dimensional superconductor
Parameshwar R. Pasnoori, Patrick Azaria, Colin Rylands +1
The interplay between bulk properties and boundary conditions in one-dimensional quantum systems, gives rise to many intriguing phenomena. These include the emergence of zero energ…
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…
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…
Entanglement in dual unitary quantum circuits with impurities
Shachar Fraenkel, Colin Rylands
Bipartite entanglement entropy is one of the most useful characterizations of universal properties in a many-body quantum system. Far from equilibrium, there exist two highly effec…
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 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…
Translation symmetry restoration under random unitary dynamics
Katja Klobas, Colin Rylands, Bruno Bertini
The finite parts of a large, locally interacting many-body system prepared out-of-equilibrium eventually equilibrate. Characterising the underlying mechanisms of this process and i…
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…
Full Counting Statistics of Charge in Quenched Quantum Gases
David X. Horvath, Colin Rylands
Unless constrained by symmetry, measurement of an observable on an ensemble of identical quantum systems returns a distribution of values which are encoded in the full counting sta…
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…
