Chaos and moduli space volumes in unorientable JT gravity
Jarod Tall, Torsten Weber, Juan Diego Urbina +1
We show the late time, or scaled, limit of the canonical spectral form factor (SFF) in unorientable JT gravity agrees with universal random matrix theory (RMT) up to genus one…
Quasiclassical theory of out-of-time-ordered correlators
Thomas R. Michel, Juan Diego Urbina, Peter Schlagheck
Out-of-time-ordered correlators (OTOCs), defined via the squared commutator of a time-evolving and a stationary operator, represent observables that provide useful indicators for c…
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…
Many-body density of states of bosonic and fermionic gases: a combinatorial approach
Carolyn Echter, Georg Maier, Juan-Diego Urbina +2
We use a combinatorial approach to obtain exact expressions for the many-body density of states of fermionic and bosonic gases with equally spaced single-particle spectra. We ident…
On a Matrix Ensemble for Arbitrary Complex Quantum Systems
William E. Salazar, Juan Diego Urbina, Javier Madroñero
We present a comprehensive analytical study of a variation of the eigenvector ensemble initially proposed by Deutsch for the foundations of the Eigenstate Thermalization Hypothesis…
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 o…
