Flows in the space of interacting chiral boson theories Open
We study interacting theories of N left-moving and N¯ right-moving Floreanini-Jackiw bosons in two dimensions. A parametrized family of such theories is shown to enjoy (nonmanifest) Lorentz invariance if and only if its Lagrangian obeys a …

The holographic duality conjectures a relation between strongly coupled quantum systems and quantum gravity in higher-dimensional spacetimes. Gravitational theories in two and three dimensions are meaningful examples for classical and quan…

We study interacting theories of $N$ left-moving and $\overline{N}$ right-moving Floreanini-Jackiw bosons in two dimensions. A parameterized family of such theories is shown to enjoy (non-manifest) Lorentz invariance if and only if its Lag…

Anisotropic compactification of nonrelativistic M-theory Open
A bstract We study a decoupling limit of M-theory where the three-form gauge potential becomes critical. This limit leads to nonrelativistic M-theory coupled to a non-Lorentzian spacetime geometry. Nonrelativistic M-theory is U-dual to M-t…

We calculate the \\( \\mathcal{S} \\)-multiplets for two-dimensional Euclidean \\( \\mathcal{N} \\) = (0, 2) and \\( \\mathcal{N} \\) = (2, 2) superconformal field theories under the T\\( \\overline{T} \\) deformation at leading order of p…

Probing holography in -adic CFT Open
We holographically calculate the partition functions of certain types of isotropic sectors of the CFTs dual to Bruhat-Tits trees and $p$-adic BTZ black holes. Along the way, we propose new spectral decompositions of the Laplacian operator …

Root-$T \overline{T}$ Deformed Boundary Conditions in Holography Open
We develop the holographic dictionary for pure $\mathrm{AdS}_3$ gravity where the Lagrangian of the dual $2d$ conformal field theory has been deformed by an arbitrary function of the energy-momentum tensor. In addition to the $T \overline{…

$T\bar{T}$ in JT Gravity and BF Gauge Theory Open
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\overbar{T}} -type deformations of the (0+1) …

Pure three-dimensional gravity is a renormalizable theory with two free parameters labelled by G and \Lambda . As a consequence, correlation functions of the boundary stress tensor in AdS _3 are uniquely fixed in terms of one dimens…

Sharpening the holographic correspondence of Jackiw-Teitelboim (JT) gravity and its dual matrix model description at a finite radial cutoff $λ$ through the $T\overline{T}$ deformation is of interest. To proceed, we simplify the problem by …
