We compute the angular power spectra of the E-type and B-type lensing potentials for gravitational waves from inflation and for tensor perturbations induced by scalar perturbations. We derive...

Antti Kemppainen, Stanislav Smirnov

In this article we show the convergence of a loop ensemble of interfaces in the FK Ising model at criticality, as the lattice mesh tends to zero, to a unique conformally invariant scaling limit...

Tudor S. Ratiu, Daisuke Tarama

A natural extension of the free rigid body dynamics to the unitary group U(n) is considered. The dynamics is described by the Euler equation on the Lie algebra u(n), which has a bi-Hamiltonian...

Holomorphic fields play an important role in 2d conformal field theory. We generalize them to d>2 by introducing the notion of Cauchy conformal fields, which satisfy a first order...

Alberto S. Cattaneo, Michele Schiavina

The present paper shows that General Relativity in the ADM formalism admits a BV-BFV formulation in the sense of Cattaneo, Mnev and Reshetikhin. More precisely, for any d+1≠2 (pseudo-)Riemannian...

Ilia Itenberg, Grigory Mikhalkin, Johannes Rau

From a topological viewpoint, a rational curve in the real projective plane is generically a smoothly immersed circle and a finite collection of isolated points. We give an isotopy...

Niklas Beisert, Dennis Muller, Jan Plefka, Cristian Vergu

We perform a detailed study of the Yangian symmetry of smooth supersymmetric Maldacena-Wilson loops in planar N=4 super Yang-Mills theory. This hidden symmetry extends the global superconformal...

Chiara Boccato, Serena Cenatiempo, Benjamin Schlein

We consider the many body quantum dynamics of systems of bosons interacting through a two-body potential N3β−1V(Nβx), scaling with the number of particles N. For 0<β<...

Alain-Sol Sznitman

We consider a general enough set-up and obtain a refinement of the coupling between the Gaussian free field and random interlacements recently constructed by Titus Lupu in arXiv:1402.0298. We...

Antti Knowles, Ron Rosenthal

We consider the adjacency operator of the Linial-Meshulam model for random simplicial complexes on n vertices, where each d-cell is added independently with probability p to the...

Julian Adamek, David Daverio, Ruth Durrer, Martin Kunz

Numerical simulations are a versatile tool providing insight into the complicated process of structure formation in cosmology. This process is mainly governed by gravity, which is the dominant...

Wei Qian, Wendelin Werner

We study the structure of Brownian loop-soup clusters in two dimensions. Among other things, we obtain the following decomposition of the clusters with critical intensity: When one conditions a...
