A Study of the SYK Model with Twisted Boundary Conditions
Jeff Murugan, Ruach Pillay Slayen, Hendrik J. R. Van Zyl
We study a version of the 2-body Sachdev-Ye-Kitaev (SYK) model whose complex fermions exhibit twisted boundary conditions on the thermal circle. As we show, this is physicall…
Notes on the Squashed Sphere Lowest Landau Level
Jeff Murugan, Jonathan P. Shock, Ruach Pillay Slayen
In a recent article, we were motivated by the question of whether any of the remarkable condensed matter phenomena, such as the quantum Hall effect (QHE), the Integer quantum Hall…
Chaos and Scrambling in Quantum Small Worlds
Jean-Gabriel Hartmann, Jeff Murugan, Jonathan P. Shock
Quantum small-worlds are quantum many-body systems that interpolate between completely ordered (nearest-neighbour, next-to-nearest-neighbour etc.) and completely random interaction…
The Information Metric on the moduli space of instantons with global symmetries
Emanuel Malek, Jeff Murugan, Jonathan P Shock
In this note we revisit Hitchin's prescription \cite{Hitchin} of the Fisher metric as a natural measure on the moduli space of instantons that encodes the space-time symmetries of…
Entanglement entropy of -vacua in de Sitter space
Sugumi Kanno, Jeff Murugan, Jonathan P. Shock +1
We consider the entanglement entropy of a free massive scalar field in the one parameter family of -vacua in de Sitter space by using a method developed by Maldacena and Pimente…
