Thermodynamics and DC conductivity of 2D anisotropic fluids from axion holography
Alfonso Ballon-Bayona, Jonathan P. Shock, Dimitrios Zoakos
We investigate a strongly coupled finite-density anisotropic fluid in dimensions dual to an asymptotically AdS black brane that is a solution of Einstein-Maxwell-Axion theory…
Magnetising the Super Yang-Mills plasma
Alfonso Ballon-Bayona, Jonathan P. Shock, Dimitrios Zoakos
We investigate the thermodynamics of the anisotropic magnetic black brane solution found by D'Hoker and Kraus arXiv:0908.3875. This solution is the gravity dual of a st…
Remarks on Fermions in a Dipole Magnetic Field
Jeff Murugan, Jonathan P. Shock, Ruach Pillay Slayen
This work is a continuation of our recent study of non-relativistic charged particles, confined to a sphere enclosing a magnetic dipole at its center. In this sequel, we extend our…
Magnetic catalysis and the chiral condensate in holographic QCD
Alfonso Ballon-Bayona, Jonathan P. Shock, Dimitrios Zoakos
We investigate the effect of a non-zero magnetic field on the chiral condensate using a holographic QCD approach. We extend the model proposed by Iatrakis, Kiritsis and Paredes in…
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…
Astrophysical Quantum Matter: Spinless charged particles on a magnetic dipole sphere
Jeff Murugan, Jonathan P. Shock, Ruach Pillay Slayen
We consider the quantum mechanics of a spinless charged particle on a 2-dimensional sphere. When threaded with a magnetic monopole field, this is the well-known Haldane sphere that…
A universal order parameter for Inverse Magnetic Catalysis
Alfonso Ballon-Bayona, Matthias Ihl, Jonathan P. Shock +1
We revisit the chiral transition in the finite density Sakai-Sugimoto model and find that, at fixed temperature , the magnetisation near the critical line acts as an or…
Quantum discord in de Sitter space
Sugumi Kanno, Jonathan P. Shock, Jiro Soda
We study quantum discord between two free modes of a massive scalar field in a maximally entangled state in de Sitter space. We introduce two observers, one in a global chart and t…
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 negativity in the multiverse
Sugumi Kanno, Jonathan P. Shock, Jiro Soda
We explore quantum entanglement between two causally disconnected regions in the multiverse. We first consider a free massive scalar field, and compute the entanglement negativity…
Particle-vortex and Maxwell duality in the /ABJM correspondence
Jeff Murugan, Horatiu Nastase, Nitin Rughoonauth +1
We revisit the notion of particle-vortex duality in abelian theories of complex scalar fields coupled to gauge fields, formulating the duality as a transformation at the level of t…

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…
