Modular theory and symmetry resolution in hyperfinite von Neumann algebras

Giuseppe Di Giulio, Moritz Dorband, Johanna Erdmenger +1

We study modular theory in hyperfinite von Neumann algebras, i.e. in those of type II or type III, from the viewpoint of a subregion charge sector decomposition. We address this sy…

Subsystem complexity after a local quantum quench

Giuseppe Di Giulio, Erik Tonni

We study the temporal evolution of the circuit complexity after the local quench where two harmonic chains are suddenly joined, choosing the initial state as the reference state. W…

Subsystem complexity after a global quantum quench

Giuseppe Di Giulio, Erik Tonni

We study the temporal evolution of the circuit complexity for a subsystem in harmonic lattices after a global quantum quench of the mass parameter, choosing the initial reduced den…

Entanglement Hamiltonians for non-critical quantum chains

Viktor Eisler, Giuseppe Di Giulio, Erik Tonni +1

We study the entanglement Hamiltonian for finite intervals in infinite quantum chains for two different free-particle systems: coupled harmonic oscillators and fermionic hopping mo…

Entanglement and symmetry resolution in two dimensional free quantum field theories

Sara Murciano, Giuseppe Di Giulio, Pasquale Calabrese

We present a thorough analysis of the entanglement entropies related to different symmetry sectors of free quantum field theories (QFT) with an internal U(1) symmetry. We provide e…

Complexity of mixed Gaussian states from Fisher information geometry

Giuseppe Di Giulio, Erik Tonni

We study the circuit complexity for mixed bosonic Gaussian states in harmonic lattices in any number of dimensions. By employing the Fisher information geometry for the covariance…

Full counting statistics in the gapped XXZ spin chain

Pasquale Calabrese, Mario Collura, Giuseppe Di Giulio +1

We exploit the knowledge of the entanglement spectrum in the ground state of the gapped XXZ spin chain to derive asymptotic exact results for the full counting statistics of the tr…

Entanglement hamiltonians in 1D free lattice models after a global quantum quench

Giuseppe Di Giulio, Raul Arias, Erik Tonni

We study the temporal evolution of the entanglement hamiltonian of an interval after a global quantum quenchin free lattice models in one spatial dimension. In a harmonic chain we…
