Topological chiral-gain in a Berry dipole material. [PDF]

Nanophotonics
Abstract Recent studies have shown that low‐symmetry conductors under static electric bias offer a pathway to realize chiral gain, where the non‐Hermitian optical response of the material is controlled by the spin angular momentum of the wave. In this work, we uncover the topological nature of chiral gain and demonstrate how a static electric bias ...

Chern-Simons supergravity on supergroup manifolds

Journal of High Energy Physics, 2020
We construct N=1 d=3 AdS supergravity within the group manifold approach and compare it with Achucarro-Townsend Chern-Simons formulation of the same theory.

New phase transitions in Chern–Simons matter theory

Nuclear Physics B, 2016
Applying the machinery of random matrix theory and Toeplitz determinants we study the level k, U(N) Chern–Simons theory coupled with fundamental matter on S2×S1 at finite temperature T. This theory admits a discrete matrix integral representation, i.e. a

Supersymmetric Chern–Simons theory in presence of a boundary in the light-like direction

Nuclear Physics B, 2016
In this paper, we will analyze a three dimensional supersymmetric Chern–Simons theory on a manifold with a boundary. The boundary we will consider in this paper will be defined by n⋅x=0, where n is a light-like vector.

Renormalization group flow of Chern-Simons boundary conditions and generalized Ricci tensor

Journal of High Energy Physics, 2020
We find a Chern-Simons propagator on the ball with the chiral boundary condition. We use it to study perturbatively Chern-Simons boundary conditions related to 2-dim σ-models and to Poisson-Lie T-duality.

The Hilbert space of large N Chern-Simons matter theories

Journal of High Energy Physics, 2022
We demonstrate that the known expressions for the thermal partition function of large N Chern-Simons matter theories admit a simple Hilbert space interpretation as the partition function of an associated ungauged large N matter theory with one additional

Three-dimensional non-relativistic supergravity and torsion

European Physical Journal C: Particles and Fields, 2022
In this paper we present a torsional non-relativi-stic Chern–Simons (super)gravity theory in three spacetime dimensions. We start by developing the non-relativistic limit of the purely bosonic relativistic teleparallel Chern–Simons formulation of gravity.

Teichmüller TQFT vs. Chern-Simons theory

Journal of High Energy Physics, 2018
Teichmüller TQFT is a unitary 3d topological theory whose Hilbert spaces are spanned by Liouville conformal blocks. It is related but not identical to PSL(2, ℝ) Chern-Simons theory.

$T\bar{T}$ in JT Gravity and BF Gauge Theory

SciPost Physics, 2022
JT gravity has a first-order formulation as a two-dimensional BF theory, which can be viewed as the dimensional reduction of the Chern-Simons description of $3d$ gravity. We consider $T\bar{T}$-type deformations of the $(0+1)$-dimensional dual to this
