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-…
Locality Outside Extremal Black Holes
Hessamaddin Arfaei, Alek Bedroya, Mahdi Torabian
Motivated by string theory, we propose that non-local quantum corrections to large extremal black holes must be suppressed by local higher-derivative terms (classical corrections).…
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…
Swampland de Sitter Conjectures in No-Scale Supergravity Models
Ida M. Rasulian, Mahdi Torabian, Liliana Velasco-Sevilla
It is challenging to construct explicit and controllable models that realize de Sitter solutions in string compactifications. This difficulty is the main motivation for the Refined…
5-Dimensional Chern-Simons Gauge Theory on an Interval: Massive Spin-2 Theory from Symmetry Breaking via Boundary Conditions
Mahdi Torabian
In this note, we revisit the 4-dimensional theory of massive gravity through compactification of an extra dimension and geometric symmetry breaking. We dimensionally reduce the 5-d…
