Refined quantum Lyapunov exponents from replica out-of-time-order correlators
DA Trunin - Physical Review D, 2023 - APS
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 …

Commuting SYK: a pseudo-holographic model
P Gao - Journal of High Energy Physics, 2024 - Springer
A bstract In this work, we study a type of commuting SYK model in which all terms in the
Hamiltonian are commutative to each other. Because of the commutativity, this model has a …

Tuning photon-mediated interactions in a multimode cavity: From supersolid to insulating droplets hosting phononic excitations
Ultracold atoms trapped in laser-generated optical lattices serve as a versatile platform for
quantum simulations. However, as these lattices are infinitely stiff, they do not allow to …

Conductance and thermopower fluctuations in interacting quantum dots
We model an interacting quantum dot of electrons by a Hamiltonian with random and all-to-
all single-particle hopping (of root-mean-square strength t) and two-particle interactions (of …

Quantum simulation of the Sachdev-Ye-Kitaev model using time-dependent disorder in optical cavities
R Baumgartner, P Pelliconi, S Bandyopadhyay… - arXiv preprint arXiv …, 2024 - arxiv.org
The Sachdev-Ye-Kitaev (SYK) model is a paradigm for extreme quantum chaos, non-Fermi-
liquid behavior, and holographic matter. Yet, the dense random all-to-all interactions that …
