Entanglement Asymmetry in Random Quantum Automata
Olalla A. Castro-Alvaredo, Dávid Szász-Schagrin, Michele Mazzoni
We investigate the subsystem entanglement asymmetry in random quantum automaton ensembles, which are generated by permuting the basis states in the Hilbert space and applying globa…
Generalized hydrodynamics of free fermions under extensive-charge monitoring
Pablo Bayona-Pena, Michele Mazzoni, Lorenzo Piroli
We study transport dynamics of free fermions subject to the external monitoring of a conserved charge over an extensive region. Focusing on bipartition protocols, we consider monit…
An asymmetry lower bound on fermionic non-Gaussianity
Filiberto Ares, Michele Mazzoni, Sara Murciano +3
Fermionic Gaussian states are a fundamental tool in many-body physics, faithfully representing non-interacting quantum systems and allowing for efficient numerical simulations. Giv…
Breaking global symmetries with locality-preserving operations
Michele Mazzoni, Luca Capizzi, Lorenzo Piroli
In the general framework of quantum resource theories, one typically only distinguishes between operations that can or cannot generate the resource of interest. In many-body settin…
Entanglement dynamics and Page curves in random permutation circuits
Dávid Szász-Schagrin, Michele Mazzoni, Bruno Bertini +2
The characterization of ensembles of many-qubit random states and their realization via quantum circuits are crucial tasks in quantum-information theory. In this work, we study the…
Time Evolution of the Symmetry Resolved Entanglement Entropy after a Mass Quench
Federico Rottoli, Michele Mazzoni, Fabio Sailis +1
In this paper we investigate the properties of the symmetry resolved entanglement entropy after a mass quench in the Ising field theory. Since the theory is free and the post-quenc…
Entanglement content of kink excitations
Luca Capizzi, Michele Mazzoni
Quantum one-dimensional systems in their ordered phase admit kinks as elementary excitations above their symmetry-broken vacua. While the scattering properties of the kinks resembl…
Generalised Hydrodynamics of -Deformed Integrable Quantum Field Theories
Riccardo Travaglino, Michele Mazzoni, Olalla A. Castro-Alvaredo
In this paper we evaluate the averages of conserved densities and currents associated to charges of generic spin in (1+1)-dimensional massive integrable Quantum Field Theories pert…
Expectation Values of Conserved Charges in Integrable Quantum Field Theories out of Thermal Equilibrium
Michele Mazzoni, Riccardo Travaglino, Olalla A. Castro-Alvaredo
In this work we present a computation of the averages of conserved charge densities and currents of (1+1)-dimensional Integrable Quantum Field Theories in Generalised Gibbs Ensembl…
Entanglement asymmetry in the ordered phase of many-body systems: the Ising Field Theory
Luca Capizzi, Michele Mazzoni
Global symmetries of quantum many-body systems can be spontaneously broken. Whenever this mechanism happens, the ground state is degenerate and one encounters an ordered phase. In…
Symmetry Resolved Entanglement of Excited States in Quantum Field Theory III: Bosonic and Fermionic Negativity
Luca Capizzi, Michele Mazzoni, Olalla A. Castro-Alvaredo
In two recent works, we studied the symmetry resolved Rényi entropies of quasi-particle excited states in quantum field theory. We found that the entropies display many model-indep…
Two-Point Functions of Composite Twist Fields in the Ising Field Theory
Olalla A. Castro-Alvaredo, Michele Mazzoni
All standard measures of bipartite entanglement in one-dimensional quantum field theories can be expressed in terms of correlators of branch point twist fields, here denoted by $\m…
Symmetry Resolved Entanglement of Excited States in Quantum Field Theory II: Numerics, Interacting Theories and Higher Dimensions
Luca Capizzi, Cecilia De Fazio, Michele Mazzoni +2
In a recent paper we studied the entanglement content of zero-density excited states in complex free quantum field theories, focusing on the symmetry resolved entanglement entropy…
Symmetry Resolved Entanglement of Excited States in Quantum Field Theory I: Free Theories, Twist Fields and Qubits
Luca Capizzi, Olalla A. Castro-Alvaredo, Cecilia De Fazio +2
The excess entanglement resulting from exciting a finite number of quasiparticles above the ground state of a free integrable quantum field theory has been investigated quite exten…
The Staircase Model: Massless Flows and Hydrodynamics
Michele Mazzoni, Octavio Pomponio, Olalla A. Castro-Alvaredo +1
The staircase model is a simple generalization of the sinh-Gordon model, obtained by complexifying the coupling constant. This produces a new theory with many interesting features.…
