Spinning Billiards and Chaos
Jacob S. Lund, Jeff Murugan, Jonathan P. Shock
We investigate the impact of internal spin on chaos in billiard systems. Extending the standard point-particle billiard by coupling translational and rotational degrees of freedom…
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…
Probability Density Functions from the Fisher Information Metric
T. Clingman, Jeff Murugan, Jonathan P. Shock
We show a general relation between the spatially disjoint product of probability density functions and the sum of their Fisher information metric tensors. We then utilise this resu…
