3d SUSY enhancement and non-semisimple TQFTs from four dimensions

Arash Arabi Ardehali, Dongmin Gang, Neville Joshua Rajappa +1

It has been recently shown that the celebrated SCFT/VOA correspondence can be bridged via three-dimensional field theories arising from a specific R-symmetry twisted circle…

Bridging 4D QFTs and 2D VOAs via 3D high-temperature EFTs

Arash Arabi Ardehali, Mykola Dedushenko, Dongmin Gang +1

The high-temperature limit of the superconformal index, especially on higher sheets, often captures useful universal information about a theory. In 4d superconforma…

Confinement from Distance in Metric Space and its Relation to Cosmological Constant

Amineh Mohseni, Mahdi Torabian

We argue that, in a theory of quantum gravity, the gauge coupling and the confinement scale of a gauge theory are related to distance in the space of metric configurations, and in…

On Torsion Contribution to Chiral Anomaly via Nieh-Yan Term

Ida M. Rasulian, Mahdi Torabian

In this note we present a solution to the question of whether or not, in the presence of torsion, the topological Nieh-Yan term contributes to chiral anomaly. The integral of Nieh-…

Holographic Hydrodynamics of {\it Tilted} Dirac Materials

A. Moradpouri, S. A. Jafari, Mahdi Torabian

We present a gravity dual to a quantum material with tilted Dirac cone in 2+1 dimensional spacetime. In this many-body system the electronics degrees of freedom are strongly-couple…

Higgs in Nilpotent Supergravity: Vacuum Energy and Festina Lente

Amineh Mohseni, Mahdi Torabian

In this note we study supergravity models with constrained superfields. We construct a supergravity framework in which all (super)symmetry breaking dynamics happen in vacuum with n…
