Symmetry resolution of the computable cross-norm negativity of two disjoint intervals in the massless Dirac field theory
Andrea Bruno, Filiberto Ares, Sara Murciano +1
We investigate how entanglement in the mixed state of a quantum field theory can be described using the cross-computable norm or realignment (CCNR) criterion, employing a recently…
An entanglement asymmetry study of black hole radiation
Filiberto Ares, Sara Murciano, Lorenzo Piroli +1
Hawking's discovery that black holes can evaporate through radiation emission has posed a number of questions that with time became fundamental hallmarks for a quantum theory of gr…
Symmetry-resolved Entanglement Entropy, Spectra & Boundary Conformal Field Theory
Yuya Kusuki, Sara Murciano, Hirosi Ooguri +1
We perform a comprehensive analysis of the symmetry-resolved (SR) entanglement entropy (EE) for one single interval in the ground state of a D conformal field theory (CFT), th…
Entanglement asymmetry and quantum Mpemba effect in the XY spin chain
Sara Murciano, Filiberto Ares, Israel Klich +1
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…
Finite temperature negativity Hamiltonians of the massless Dirac fermion
Federico Rottoli, Sara Murciano, Pasquale Calabrese
The negativity Hamiltonian, defined as the logarithm of a partially transposed density matrix, provides an operatorial characterisation of mixed-state entanglement. However, so far…
Symmetry-resolved entanglement in fermionic systems with dissipation
Sara Murciano, Pasquale Calabrese, Vincenzo Alba
We investigate symmetry-resolved entanglement in out-of-equilibrium fermionic systems subject to gain and loss dissipation, which preserves the block-diagonal structure of the redu…
Full counting statistics and symmetry resolved entanglement for free conformal theories with interface defects
Luca Capizzi, Sara Murciano, Pasquale Calabrese
We consider the ground state of two species of one-dimensional critical free theories coupled together via a conformal interface. They have an internal global symmetry and w…
Measurement-altered Ising quantum criticality
Sara Murciano, Pablo Sala, Yue Liu +2
Quantum critical systems constitute appealing platforms for the exploration of novel measurement-induced phenomena due to their innate sensitivity to perturbations. We study the im…
Lack of symmetry restoration after a quantum quench: an entanglement asymmetry study
Filiberto Ares, Sara Murciano, Eric Vernier +1
We consider the quantum quench in the XX spin chain starting from a tilted Néel state which explicitly breaks the symmetry of the post-quench Hamiltonian. Very surprisingly,…
