- Title: Random Matrix Statistics in Propagating Correlation Fronts of Fermions
- Authors: Kazuya Fujimoto, Tomohiro Sasamoto
- Abstract summary: We study propagating correlation fronts in non-interacting fermions on a one-dimensional lattice starting from an alternating state, where the fermions occupy every other site.
We find that, in the long-time regime, all the moments of dynamical fluctuations around the correlation fronts are described by the universal correlation functions of Gaussian and symplectic random matrices at the soft edge.

- Abstract: We theoretically study propagating correlation fronts in non-interacting
fermions on a one-dimensional lattice starting from an alternating state, where
the fermions occupy every other site. We find that, in the long-time asymptotic
regime, all the moments of dynamical fluctuations around the correlation fronts
are described by the universal correlation functions of Gaussian orthogonal and
symplectic random matrices at the soft edge. Our finding here sheds light on a
hitherto unknown connection between random matrix theory and correlation
propagation in quantum dynamics.

We show that the randomness of chaotic eigenstates in interacting quantum systems hides subtle correlations imposed by their finite energy per particle.
These correlations are revealed when Berrys approach for chaotic eigenfunctions in single-particle systems is lifted into many-body space.
We then identify the universality of both the cross-correlations and the Gaussian distribution of expansion coefficients as the signatures of chaotic eigenstates.

We study phase transitions occurring in the stationary state of the dynamics of integrable many-body non-Hermitian Hamiltonians.
We observe that the entanglement phase transitions occurring in the stationary state have the same nature as that occurring in the vacuum of the non-hermitian Hamiltonian.

We show the presence of a topological phase transition that is of a different universality class than that observed in stroboscopic projective circuits.
We find that this entanglement transition is well identified by a combination of the bipartite entanglement entropy and the topological entanglement entropy.

We work in the framework of the dissipative Dicke model which is archetypal of symmetry-breaking phase transitions in open quantum systems.
We establish that the Liouvillian describing the quantum dynamics exhibits distinct spectral features of integrable and chaotic character.
Our approach can be readily adapted for classifying the nature of quantum dynamics across dissipative critical points in other open quantum systems.
