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…

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…

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…
