Crystalline Spectral Form Factors
Dmitrii A. Trunin, David A. Huse
We investigate crystalline-like behavior of the spectral form factor in unitary quantum systems with extremely strong eigenvalue repulsion. Using a low-temperature Coulomb gas as a…
Streamlined Krylov construction and classification of ergodic Floquet systems
Nikita Kolganov, Dmitrii A. Trunin
We generalize Krylov construction to periodically driven (Floquet) quantum systems using the theory of orthogonal polynomials on the unit circle. Compared to other approaches, our…
Quantum chaos without false positives
Dmitrii A. Trunin
Out-of-time-order correlators are widely used as an indicator of quantum chaos, but give false-positive quantum Lyapunov exponents for integrable systems with isolated saddle point…
Refined quantum Lyapunov exponents from replica out-of-time-order correlators
Dmitrii A. Trunin
We suggest a new indicator of quantum chaos based on the logarithmic out-of-time-order correlator. On the one hand, this indicator correctly reproduces the average classical Lyapun…
Enhancement of particle creation in nonlinear resonant cavities
Dmitrii A. Trunin
The rate of particle creation in a resonantly oscillating cavity is known to be approximately constant at large evolution times. Employing the Schwinger-Keldysh diagrammatic techni…
Classical and quantum butterfly effect in nonlinear vector mechanics
Nikita Kolganov, Dmitrii A. Trunin
We establish the correspondence between the classical and quantum butterfly effects in nonlinear vector mechanics with the broken symmetry. On one hand, we analytically calc…
