Nonsingular Black Hole
Ali H. Chamseddine, Viatcheslav Mukhanov
We consider the Schwarzschild black hole and show how, in a theory with limiting curvature, the physical singularity "inside it" is removed. The resulting spacetime is geodesically…
Resolving Cosmological Singularities
Ali H. Chamseddine, Viatcheslav Mukhanov
We find a simple modification of the longitudinal mode in General Relativity which incorporates the idea of limiting curvature. In this case the singularities in contracting Friedm…
Finite temperature quantum field theory in the heat kernel method
Yuri V. Gusev
The trace of the heat kernel in a (D+1)-dimensional Euclidean spacetime (integer D > 1) is used to derive the free energy in finite temperature field theory. The spacetime presents…
On the integral law of thermal radiation
Yuri V. Gusev
The integral law of thermal radiation by finite size emitters is studied. Two geometrical characteristics of a radiating body or a cavity, its volume and its boundary area, define…
The most powerful astrophysical events: Gravitational-wave peak luminosity of binary black holes as predicted by numerical relativity
David Keitel, Xisco Jiménez Forteza, Sascha Husa +9
For a brief moment, a binary black hole (BBH) merger can be the most powerful astrophysical event in the visible universe. Here we present a model fit for this gravitational-wave p…
Ghost classes in -rank two orthogonal Shimura varieties
Jitendra Bajpai, Matias Victor Moya Giusti
In this article, the existence of ghost classes for the Shimura varieties associated to algebraic groups of orthogonal similitudes of signature (2, n) is investigated. We make use…
The boundary length and point spectrum enumeration of partial chord diagrams using cut and join recursion
Jørgen Ellegaard Andersen, Hiroyuki Fuji, Robert C. Penner +1
We introduce the boundary length and point spectrum, as a joint generalization of the boundary length spectrum and boundary point spectrum in arXiv:1307.0967. We establish by cut-a…
Partial chord diagrams and matrix models
Jørgen Ellegaard Andersen, Hiroyuki Fuji, Masahide Manabe +2
In this article, the enumeration of partial chord diagrams is discussed via matrix model techniques. In addition to the basic data such as the number of backbones and chords, we al…
Enumeration of chord diagrams via topological recursion and quantum curve techniques
Jørgen Ellegaard Andersen, Hiroyuki Fuji, Masahide Manabe +2
In this paper we consider the enumeration of orientable and non-orientable chord diagrams. We show that this enumeration is encoded in appropriate expectation values of the -def…
Jacobi-Maupertuis-Eisenhart metric and geodesic flows
Sumanto Chanda, G. W. Gibbons, Partha Guha
The Jacobi metric derived from the line element by one of the authors is shown to reduce to the standard formulation in the non-relativistic approximation. We obtain the Jacobi met…
The Bethe ansatz for the six-vertex and XXZ models: an exposition
Hugo Duminil-Copin, Maxime Gagnebin, Matan Harel +2
In this paper, we review a few known facts on the coordinate Bethe ansatz. We present a detailed construction of the Bethe ansatz vector and energy , which satisfy …
Hyperlogarithms and periods in Feynman amplitudes
Ivan Todorov
The role of hyperlogarithms and multiple zeta values (and their generalizations) in Feynman amplitudes is being gradually recognized since the mid 1990's. The present lecture provi…
Discontinuity of the phase transition for the planar random-cluster and Potts models with
Hugo Duminil-Copin, Maxime Gagnebin, Matan Harel +2
We prove that the -state Potts model and the random-cluster model with cluster weight undergo a discontinuous phase transition on the square lattice. More precisely, we sh…
Three-body problem in 3D space: ground state, (quasi)-exact-solvability
Alexander V Turbiner, Willard Miller, Adrian M Escobar-Ruiz
We study aspects of the quantum and classical dynamics of a -body system in 3D space with interaction depending only on mutual distances. The study is restricted to solutions in…
Note on Nonlinear Schrödinger Equation, KdV Equation and 2D Topological Yang-Mills-Higgs Theory
Jun Nian
In this paper we discuss the relation between the (1+1)D nonlinear Schrödinger equation and the KdV equation. By applying the boson/vortex duality, we can map the classical nonline…
Return probability and recurrence for the random walk driven by two-dimensional Gaussian free field
Marek Biskup, Jian Ding, Subhajit Goswami
Given any and for denoting a sample of the two-dimensional discrete Gaussian free field on pinned at the origin, we consider the…
On the integrable gravity coupled to fermions
Vladimir A. Belinski
In the present letter we indicate an extension of the pure gravity inverse scattering integration technique to the case when fermions (introduced on the base of supersymmetry) are…
Upper bounds on Liouville first passage percolation and Watabiki's prediction
Jian Ding, Subhajit Goswami
Given a planar continuum Gaussian free field in a domain with Dirichlet boundary condition and any , we let $\{h_δ^{\mathcal U}(v): v\in \mathcal…
Schottky groups and maximal representations
Jean-Philippe Burelle, Nicolaus Treib
We describe a construction of Schottky type subgroups of automorphism groups of partially cyclically ordered sets. We apply this construction to the Shilov boundary of a Hermitian…
Lower bounds for Lyapunov exponents of flat bundles on curves
Alex Eskin, Maxim Kontsevich, Martin Moeller +1
Consider a flat bundle over a complex curve. We prove a conjecture of Fei Yu that the sum of the top k Lyapunov exponents of the flat bundle is always greater or equal to the degre…
Spinning test-body orbiting around Schwarzschild black hole: circular dynamics and gravitational-wave fluxes
Enno Harms, Georgios Lukes-Gerakopoulos, Sebastiano Bernuzzi +1
We consider a spinning test-body in circular motion around a nonrotating black hole and analyze different prescriptions for the body's dynamics. We compare, for the first time, the…
Gravitational scattering, post-Minkowskian approximation and Effective One-Body theory
Thibault Damour
A novel approach to the Effective One-Body description of gravitationally interacting two-body systems is introduced. This approach is based on the post-Minkowskian approximation s…

High-order tail in Kerr spacetime
Marc Casals, Chris Kavanagh, Adrian C. Ottewill
We investigate the late-time tail of the retarded Green function for the dynamics of a linear field perturbation of Kerr spacetime. We develop an analytical formalism for obtaining…
