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 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…
