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…
