Random matrix theory signatures in free field theory
Dmitry S. Ageev, Vasilii V. Pushkarev
We show that, within a finite window of parameter space, random matrix theory (RMT) statistics emerge in observables of a finite-volume massive free scalar field theory after a loc…
Spectral form factors for curved spacetimes with horizon
Dmitry S. Ageev, Vasilii V. Pushkarev, Anastasia N. Zueva
The spectral form factor is believed to exhibit a special type of behavior called ``dip-ramp-plateau'' in chaotic quantum systems that originates from random matrix theory. This su…
Local quenches in fracton field theory: Lieb-Robinson bound, non-causal dynamics and fractal excitation patterns
Dmitry S. Ageev, Andrey A. Bagrov, Aleksandr I. Belokon +3
We study the out-of-equilibrium dynamics induced by a local perturbation in fracton field theory. For the and -symmetric free fractonic theories, we…
Quantum quenches in fractonic field theories
Dmitry S. Ageev, Vasilii V. Pushkarev
We study out-of-equilibrium dynamics caused by global quantum quenches in fractonic scalar field theories. We consider several types of quenches, in particular, the mass quench in…
Entanglement entropy in de Sitter: no pure states for conformal matter
D. S. Ageev, I. Ya. Aref'eva, A. I. Belokon +2
In this paper, we consider the entanglement entropy of conformal matter for finite and semi-infinite entangling regions, as well as the formation of entanglement islands in four-di…
Infrared Regularization and Finite Size Dynamics of Entanglement Entropy in Schwarzschild Black Hole
D. S. Ageev, I. Ya. Aref'eva, A. I. Belokon +3
In this paper, infrared regularization of semi-infinite entangling regions and island formation for regions of finite size in the eternal Schwarzschild black hole are considered. W…
From locality to irregularity: Introducing local quenches in massive scalar field theory
Dmitry S. Ageev, Aleksandr I. Belokon, Vasilii V. Pushkarev
In this paper, we initiate the study of operator local quenches in non-conformal field theories. We consider the dynamics of excited local states in massive scalar field theory in…
