The relation between classical and quantum Lyapunov exponent and the bound on chaos in classically chaotic quantum systems
Fabian Haneder, Gerrit Caspari, Juan Diego Urbina +1
Out-of-Time-Ordered Commutators (OTOCs), representing a key diagnostic for scrambling as a facet of short-time quantum chaos, have attracted wide-ranging interest, from many-body p…

Beyond the ensemble paradigm in low dimensional quantum gravity: Schwarzian density, quantum chaos and wormhole contributions
Fabian Haneder, Juan Diego Urbina, Camilo Moreno +2
Based on periodic orbit theory we address the individual-system versus ensemble interpretation of quantum gravity from a quantum chaos perspective. To this end we show that the spe…

Unorientable topological gravity and orthogonal random matrix universality
Torsten Weber, Jarod Tall, Fabian Haneder +2
The duality of Jackiw-Teitelboim (JT) gravity and a double scaled matrix integral has led to studies of the canonical spectral form factor (SFF) in the so called scaled limit…
