Non-stabilizerness and U(1) symmetry in chaotic many-body quantum systems
Daniele Iannotti, Angelo Russotto, Barbara Jasser +2
We present exact, closed-form results for the non-stabilizerness of random pure states subject to a U(1) symmetry constraint. Using stabilizer entropy as our non-stabilizerness mon…

Symmetry breaking in chaotic many-body quantum systems at finite temperature
Angelo Russotto, Filiberto Ares, Pasquale Calabrese
Recent work has shown that the entanglement of finite-temperature eigenstates in chaotic quantum many-body local Hamiltonians can be accurately described by an ensemble of random s…

Non-Abelian entanglement asymmetry in random states
Angelo Russotto, Filiberto Ares, Pasquale Calabrese
The entanglement asymmetry measures the extent to which a symmetry is broken within a subsystem of an extended quantum system. Here, we analyse this quantity in Haar random states…
