More on OTOCs and Chaos in Quantum Mechanics -- Magnetic Fields
Cameron Beetar, Jeff Murugan
We revisit thermal out-of-time-order correlators (OTOCs) in single-particle quantum systems, focusing on magnetic billiards. Using the stadium billiard as a testbed, we compute the…
The SYK charging advantage as a random walk on graphs
Francisco Divi, Jeff Murugan, Dario Rosa
We investigate the charging dynamics of Sachdev-Ye-Kitaev (SYK) models as quantum batteries, highlighting their capacity to achieve quantum charging advantages. By analytically der…
From Dyson Models to Many-Body Quantum Chaos
Alexei Andreanov, Matteo Carrega, Jeff Murugan +3
A deep understanding of the mechanisms underlying many-body quantum chaos is one of the big challenges in contemporary theoretical physics. We tackle this problem in the context of…
Operator Delocalization in Quantum Networks
Joonho Kim, Jeff Murugan, Jan Olle +1
We investigate the delocalization of operators in non-chaotic quantum systems whose interactions are encoded in an underlying graph or network. In particular, we study how fast ope…
Neural Networks as Universal Probes of Many-Body Localization in Quantum Graphs
Cameron Beetar, Jeff Murugan, Dario Rosa
We show that a neural network, trained on the entanglement spectra of a nearest neighbor Heisenberg chain in a random transverse magnetic field, can be used to efficiently study th…
