In this Letter we study the impact on cosmological parameter estimation, from present and future surveys, due to lensing corrections on CMB temperature and polarization anisotropies beyond...

Santiago Codesido, Marcos Marino

We show that the all-orders WKB periods of one-dimensional quantum mechanical oscillators are governed by the refined holomorphic anomaly equations of topological string theory. We analyze in...

Jacob van den Berg, Pierre Nolin

We study frozen percolation on the (planar) triangular lattice, where connected components stop growing ("freeze") as soon as their "size" becomes at least N, for some parameter N≥1. The size of...

Giovanni Marozzi, Giuseppe Fanizza, Enea Di Dio, Ruth Durrer

We investigate the weak lensing corrections to the CMB temperature and polarization anisotropies. We consider all the effects beyond the leading order: post-Born corrections, LSS corrections and...

Grigory Mikhalkin, Arthur Renaudineau

The paper describes behavior of log-inflection points of curves in (\mathbb{C}^*)^2 under passing to the tropical limit. We show that such points accumulate by pairs at the midpoints of bounded...

Slava Rychkov, David Simmons-Duffin, Bernardo Zan

We discuss the 4pt function of the critical 3d Ising model, extracted from recent conformal bootstrap results. We focus on the non-gaussianity Q - the ratio of the 4pt function to its gaussian...

Giulia Cusin, Vittorio Tansella, Ruth Durrer

We compute the generation of vorticity from velocity dispersion in the dark matter fluid. For dark matter at zero temperature Helmholtz's theorem dictates that no vorticity is generated and we...

We develop a new approach to deformation quantizations of Lie bialgebras and Poisson structures which goes in two steps.
In the first step one associates to any Poisson (resp. Lie...

Hugo Duminil-Copin, Maxime Gagnebin, Matan Harel, Ioan Manolescu, Vincent Tassion

In this paper, we review a few known facts on the coordinate Bethe ansatz. We present a detailed construction of the Bethe ansatz vector \psi and energy \Lambda, which satisfy V \psi = \Lambda \...

We prove that the q-state Potts model and the random-cluster model with cluster weight q>4 undergo a discontinuous phase transition on the square lattice. More precisely, we show
-...

Alberto S. Cattaneo, Alejandro Perez

We show that the non-Abelian nature of geometric fluxes---the corner-stone in the definition of quantum geometry in the framework of loop quantum gravity (LQG)---follows directly form the...

The problem of reconstructing information on a physical system from data acquired in long sequences of direct (projective) measurements of some simple physical quantities - histories - is...
