Scattering in the static patch of de Sitter space
Emil Albrychiewicz, Yasha Neiman
We study the scattering problem in the static patch of de Sitter space, i.e. the problem of field evolution between the past and future horizons of a de Sitter observer. We calcula…
Remarks on a melonic field theory with cubic interaction
Dario Benedetti, Nicolas Delporte
We revisit the Amit-Roginsky (AR) model in the light of recent studies on Sachdev-Ye-Kitaev (SYK) and tensor models, with which it shares some important features. It is a model of…
MHV Gluon Scattering Amplitudes from Celestial Current Algebras
Shamik Banerjee, Sudip Ghosh
We show that the Mellin transform of an -point tree level MHV gluon scattering amplitude, also known as the celestial amplitude in pure Yang-Mills theory, satisfies a system of…
Islands and Uhlmann phase: Explicit recovery of classical information from evaporating black holes
Josh Kirklin
Recent work has established a route towards the semiclassical validity of the Page curve, and so provided evidence that information escapes an evaporating black hole. However, a pr…
Punctures and p-spin curves from matrix models II
S. Hikami, E. Brezin
We report here an extension of a previous work in which we have shown that matrix models provide a tool to compute the intersection numbers of p-spin curves. We discuss further an…
MHV Graviton Scattering Amplitudes and Current Algebra on the Celestial Sphere
Shamik Banerjee, Sudip Ghosh, Partha Paul
The Cachazo-Strominger subleading soft graviton theorem for a positive helicity soft graviton is equivalent to the Ward identities for currents. This n…
A Stringy theory in three dimensions and Massive Higher Spins
Evgeny Skvortsov, Tung Tran, Mirian Tsulaia
An example of a consistent theory with massive higher spin fields is constructed in flat space-time of dimension three. The action is written in the light-cone gauge. The theory ha…
Higher-spin symmetry vs. boundary locality, and a rehabilitation of dS/CFT
Adrian David, Yasha Neiman
We consider the holographic duality between 4d type-A higher-spin gravity and a 3d free vector model. It is known that the Feynman diagrams for boundary correlators can be encapsul…
On the quantization of folded strings in non-critical dimensions
Jacob Sonnenschein, Dorin Weissman
Classical rotating closed string are folded strings. At the folding points the scalar curvature associated with the induced metric diverges. As a consequence one cannot properly qu…
Spectral Form Factor for Time-dependent Matrix model
Arkaprava Mukherjee, Shinobu Hikami
The quantum chaos is related to a Gaussian random matrix model, which shows a dip-ramp-plateau behavior in the spectral form factor for the large size . The spectral form factor…
Virasoro hair and entropy for axisymmetric Killing horizons
Lin-Qing Chen, Wan Zhen Chua, Shuwei Liu +2
We show that the gravitational phase space for the near-horizon region of a bifurcate, axisymmetric Killing horizon in any dimension admits a 2D conformal symmetry algebra with cen…
Partial Deconfinement at Strong Coupling on the Lattice
Hiromasa Watanabe, Georg Bergner, Norbert Bodendorfer +5
We provide evidence for partial deconfinement -- the deconfinement of a SU() subgroup of the SU() gauge group -- by using lattice Monte Carlo simulations. We take matrix mode…
Current Algebra Formulation of Quantum Gravity and Its Application to Cosmology
Shotaro Shiba Funai, Hirotaka Sugawara
Gravity theory based on current algebra is formulated. The gauge principle rather than the general covariance combined with the equivalence principle plays the pivotal role in the…
More on Quantum Chiral Higher Spin Gravity
Evgeny Skvortsov, Tung Tran, Mirian Tsulaia
Chiral Higher Spin Gravity is unique in being the smallest higher spin extension of gravity and in having a simple local action both in flat and (anti)-de Sitter spaces. It must be…
BMS Symmetry of Celestial OPE
Shamik Banerjee, Sudip Ghosh, Riccardo Gonzo
In this paper we study the BMS symmetry of the celestial OPE of two positive helicity gravitons in Einstein theory in four dimensions. The celestial OPE is obtained by Mellin trans…
Color Confinement and Bose-Einstein Condensation
Masanori Hanada, Hidehiko Shimada, Nico Wintergerst
We propose a unified description of two important phenomena: color confinement in large- gauge theory, and Bose-Einstein condensation (BEC). We focus on the confinement/deconfin…
