Central Singularity of Three-Dimensional Kerr-de Sitter Black Holes
For three-dimensional Kerr-de Sitter space-time, we find the singular energy-momentum and spin tensor sources that generate the non-trivial geometry. The energy-momentum tensor is symmetric,…

Complex Saddles of Charged-AdS Gravitational partition function
In this paper, we consider the Euclidean partition function of uncharged and charged AdSd+1 black hole geometries in canonical and grand canonical ensemble for d≥3. It is seen that the…

Group Representations of Lorentz Transformations Extended to Superluminal Observers
We construct an extension of the proper orthochronous Lorentz group that includes space-time transformations for observers moving with superluminal relative velocities in arbitrary direction. This…

Interface line operators in N=4 SYM theories and supersymmetric indices
We study configurations of two N=4 super Yang-Mills theories of unitary gauge groups connected by the BPS interfaces involving line operators. We find strong evidence of S-duality of the…

Constraints on the resolution of spacetime singularities
What happens at spacetime singularities is poorly understood. The Penrose-Wall singularity theorem constrains possible scenarios, but until recently its key assumption--the generalized second law…

Hadamard tails from flat-space perturbation theory
The short-distance singular structure of the two-point function of a free scalar field in curved spacetime has a universal behavior that characterizes well-behaved states (called Hadamard states).…

λϕ4 as an Effective Theory in de Sitter
Effective field theories (EFTs) provide a powerful framework to parametrise unknown aspects of possible ultraviolet (UV) physics. For scalar fields in de Sitter space, however, new emergent phenomena…

The Geometry of BCFW for ABJM Loop Integrands
In this paper we investigate the loop-level geometry of ABJM theory from the perspective of lightcone geometries in dual space. This geometry admits a natural fibration, where one of the loop…

Hodge Structures of Complex Multiplication Type from Rational Conformal Field Theories

Conformal Blocks in 2d Carrollian/Galilean CFTs and Excited State Entanglement Entropy
We advance the study of flat space holography by computing the entanglement entropy of highly excited states in two-dimensional Carrollian/Galilean Conformal Field Theories (C/G CFTs). Our approach…

Matter Sourced Bubble Nucleation in the Asymmetron Scalar-Tensor Theory
We investigate how matter density distributions affect thin-wall bubble formation in the asymmetron mechanism, a scalar-tensor theory with a universal coupling to matter and explicit…

NLIE formulations for the generalized Gibbs ensemble in the sine-Gordon model
In this paper we propose two sets of nonlinear integral equations (NLIE) for describing the thermodynamics in the sine-Gordon model, when higher Lorentz spin conserved charges are also coupled to the…

Non-Commutative Geometry for D-Branes in Large R-R Field Background
We examine the role of non-commutative geometry in Dp-branes within large R-R field backgrounds. In this context, the background of a significant (p-1)-form R-R field can be effectively described…

Covariance of Scattering Amplitudes from Counting Carefully
Invariance of on-shell scattering amplitudes under field redefinitions is a well known property in field theory that corresponds to covariance of on-shell amputated connected functions. In recent…

Large-N Free Energy of Chiral N=2 Chern-Simons-Matter Theories

Gravitational dressing: from the crossed product to more general algebraic and mathematical structure
The crossed product, and consequent transition from von Neumann algebras of type III to II, is recovered from a truncation of more general gravitational dressing constructions, about certain…

Surprising one-loop finiteness of 6D half-maximal supergravities
In four dimensions, it has long been established that gravity coupled to matter exhibits ultraviolet divergences at one loop, irrespective of supersymmetry. Notably, the four-matter one-loop…

From Quantum Relative Entropy to the Semiclassical Einstein Equations
