Blobbed topological recursion for the quartic melonic tensor model

Valentin Bonzom, Stephane Dartois

Random tensor models are generalizations of random matrix models which admit $1/ N$ expansions. In this article we show that the topological recursion, a modern approach to matrix m…

Sub-diffusive electronic states in octagonal tiling

G. Trambly de Laissardière, C. Oguey, D. Mayou

We study the quantum diffusion of charge carriers in octagonal tilings. Our numerical results show a power law decay of the wave-packet spreading, $L (t) \propto t^{β}$ , characteristi…

Contact angles of a drop pinned on an incline

Joel De Coninck, francois Dunlop, Thierry Huillet

For a drop on an incline with small tilt angle or small Bond number, when the contact line is a circle, we show that the retentive force factor is exactly pi/2 at first order in th…

Death and rebirth of neural activity in sparse inhibitory networks

David Angulo-Garcia, Stefano Luccioli, Simona Olmi +1

In this paper, we clarify the mechanisms underlying a general phenomenon present in pulse-coupled heterogeneous inhibitory networks: inhibition can induce not only suppression of t…

Linearization of quasiperiodically forced circle flow beyond Brjuno condition

Raphael Krikorian, Jing Wang, Jiangong You +1

We prove that an analytic quasiperiodically forced circle flow with a not super-Liouvillean base frequency and which is close enough to some constant rotation is $C^{\infty}$ rotat…

Lattice spin models for non-Abelian Chiral Spin Liquids

P. Lecheminant, A. M. Tsvelik

We suggest a class of two-dimensional lattice spin Hamiltonians describing non-Abelian SU(2) chiral spin liquids - spin-analogues of fractional non-Abelian quantum Hall states- wit…

On the growth of Sobolev norms for NLS on $2 d$ and $3 d$ manifolds

Fabrice Planchon, Nikolay Tzvetkov, Nicola Visciglia

Using suitable modified energies we study higher order Sobolev norms' growth in time for the nonlinear Schrödinger equation (NLS) on a generic $2 d$ or $3 d$ compact manifold. In $2d…

Deformed Virasoro algebras from elliptic quantum algebras

J. Avan, L. Frappat, E. Ragoucy

We revisit the construction of deformed Virasoro algebras from elliptic quantum algebras of vertex type, generalizing the bilinear trace procedure proposed in the 90's. It allows u…

Entropic fluctuations in thermally driven harmonic networks

Vojkan Jaksic, Claude-Alain Pillet, Armen Shirikyan

We consider a general network of harmonic oscillators driven out of thermal equilibrium by coupling to several heat reservoirs at different temperatures. The action of the reservoi…

Matrix models for noncommutative algebraic manifolds

Teodor Banica, Julien Bichon

We discuss the notion of matrix model, $π : C (X) \to M_{K} (C (T))$ , for algebraic submanifolds of the free complex sphere, $X \subset S_{C, +}^{N - 1}$ . When $K \in N$ is fixed…
