We apply the large-charge limit to the first known example of a four-dimensional gauge-Yukawa theory featuring an ultraviolet interacting fixed point in all couplings. We determine the energy of...

We prove an adiabatic theorem for the Landau-Pekar equations. This allows us to derive new results on the accuracy of their use as effective equations for the time evolution generated by the...

Rinat Kashaev, Sergey Sergeev

We address the spectral problem of the normal quantum mechanical operator associated to the quantized mirror curve of the toric (almost) del Pezzo Calabi--Yau threefold called local \mathbb{P}^2...

Tomohiro Fujita, Ruth Durrer

We discuss a model which can generate scale-invariant helical magnetic fields on large scales (\lesssim 1Mpc) in the primordial universe. It is also shown that the electric conductivity becomes...

We set up a scattering experiment of matter against an impurity which separates two generic one-dimensional critical quantum systems. We compute the flux of reflected and transmitted energy,...

Kai Jiang, Tudor S. Ratiu, Nguyen Tien Zung

In this paper we prove the existence of a simultaneous local normalization for couples (X,\mathcal{G}), where X is a vector field which vanishes at a point and \mathcal{G} is a singular...

Dmitry Chelkak, Clément Hongler, Rémy Mahfouf

We discuss the magnetization M_m in the m-th column of the zig-zag layered 2D Ising model on a half-plane using Kadanoff-Ceva fermions and orthogonal polynomials techniques. Our main result...

The celebrated result by Biane-Bougerol-O'Connell relates Duistermaat-Heckman (DH) measures for coadjoint orbits of a compact Lie group G with the multi-dimensional Pitman transform of the...

Seung-Joo Lee, Wolfgang Lerche, Timo Weigand

We systematically analyse weak coupling limits for 2-form tensor fields in the presence of gravity. Such limits are significant for testing various versions of the Weak Gravity and Swampland...

Lorenz Eberhardt, Matthias R. Gaberdiel

String theory on {\rm AdS}_3 \times {\rm S}^3 \times {\rm S}^3 \times {\rm S}^1 with pure NS-NS flux and minimal flux through one of the two {\rm S}^3's is studied from a world-sheet perspective...

Anna Beliakova, Hatthew Hogancamp, Krzysztof Karol Putyra, Stephan Martin Wehrli

We construct an explicit equivalence between the (bi)category of gl(2) webs and foams and the Bar-Natan (bi)category of Temperley-Lieb diagrams and cobordisms. With this equivalence we can fix...

Nikolay Gromov, Amit Sever

We present the first-principle derivation of a weak-strong duality between the fishnet theory in four dimensions and a discretised string-like model living in five dimensions. At strong coupling...
