We consider the membrane model, that is the centered Gaussian field on *Z ^{d}* whose covariance matrix is given by the inverse of the discrete Bilaplacian. We impose a δ- pinning...

The symmetries of string theory on *{\rm AdS}_3 \times {\rm S}^3 \times \mathbb{T}^4* at the dual of the symmetric product orbifold point are described by a so-called Higher Spin Square (...

Recent work has shown that modifications of General Relativity based on the addition of a non-local term R\,\Box^{-2}R produce a dynamical model of dark energy, which is cosmologically viable...

Correlation functions of ferromagnetic spin systems satisfying a Lee-Yang property are studied. It is shown that, for classical systems in a non-vanishing uniform external magnetic field *h...*

Frozen percolation on the binary tree was introduced by Aldous around fifteen years ago, inspired by sol-gel transitions. We investigate a version of the model on the triangular lattice, where...

We compute the homotopy derivations of the properads governing even and odd Lie bialgebras as well as involutive Lie bialgebras. The answer may be expressed in terms of the Kontsevich graph...

Run 2 LHC data show hints of a new resonance in the diphoton distribution at an invariant mass of 750 GeV. We analyse the data in terms of a new boson, extracting information on its properties...

The notion of a quantizable odd Lie bialgebra is introduced. A minimal resolution of the properad governing such Lie bialgebras is constructed.

We revisit the theory of null shells in general relativity, with a particular emphasis on null shells placed at horizons of black holes. We study in detail the considerable freedom that is...

We propose exact quantization conditions for the quantum integrable systems of Goncharov and Kenyon, based on the enumerative geometry of the corresponding toric Calabi-Yau manifolds. Our...

We introduce a new formalism to study perturbations of Hassan-Rosen bigravity theory, around general backgrounds for the two dynamical metrics. In particular, we derive the general expression...
