Quantum Chaos and Diffusive Transport from Geometric Randomness
Bibek Saha, Abhishek Dhar, Sthitadhi Roy
The paper shows that quantum chaos and diffusive transport can emerge solely from geometric randomness in non‑interacting particles on random tree‑like layered graphs, with the gra…
Out-of-time-ordered Correlators in de Sitter Revisited
Alexey Milekhin, Vladimir Narovlansky, Jiuci Xu
The paper computes four‑point out‑of‑time‑ordered correlators of scalar fields in de Sitter space using the eikonal approximation to gravity, identifies an infrared issue at loop l…
Fast Scrambling in the Hyperbolic Ising Model
Goksu Can Toga, Abhishek Samlodia, Alexander F. Kemper
The paper studies how curvature in a hyperbolic (AdS2) Ising spin chain speeds up quantum information scrambling, using out-of-time-ordered correlators, Krylov complexity, and spec…
Dissipative phase transitions and chaos in two-photon driven quantum optomechanics
Giovanni Bragadin, Filippo Ferrari, Lorenzo Fioroni +4
The paper studies a two‑photon‑driven optomechanical system, showing it can exhibit both first‑ and second‑order dissipative phase transitions, symmetry breaking, and chaotic dynam…
Emergent quantum chaos from correlations on a random graph
Mrinal Sarkar, Valerio Pagni, Tilman Enss +1
The paper shows that a one‑dimensional lattice with sparse, long‑range random bonds can produce quantum‑chaotic spectral correlations and a localization transition, even without on…
