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...

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...

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...

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...

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...

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

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 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...

This note describes a quantization of the relational symplectic groupoid (RSG) for a constant Poisson structure using the BV-BFV formalism and shows how this induces the Moyal deformation...

We define a family {\rm KV}^{(g,n)} of Kashiwara-Vergne problems associated with compact connected oriented 2-manifolds of genus g with n+1 boundary components. The problem {\rm KV}^{(0,3)} is...
