Two-dimensional optical chimera states in an array of coupled waveguide resonators

M. G. Clerc, S. Coulibaly, M. A. Ferré +1

Two-dimensional arrays of coupled waveguides or coupled microcavities allow to confine and manipulate light. Based on a paradigmatic envelope equation, we show that these devices,…

Gapped vegetation patterns: crown/root allometry and snaking bifurcation

Jaime Cisternas, Daniel Escaff, M. Clerc +2

Nonuniform spatial distributions of vegetation in scarce environments consist of either gaps, bands often called tiger bush or patches that can be either self-organized or spatiall…

A note on the Regularity of Center-Outward Distribution and Quantile Functions

Eustasio del Barrio, Alberto González-Sanz, Marc Hallin

We provide sufficient conditions under which the center-outward distribution and quantile functions introduced in Chernozhukov et al.~(2017) and Hallin~(2017) are homeomorphisms, t…

The Hyperspherical Harmonics method: a tool for testing and improving nuclear interaction models

L. E. Marcucci, J. Dohet-Eraly, L. Girlanda +3

The Hyperspherical Harmonics (HH) method is one of the most accurate techniques to solve the quantum mechanical problem for nuclear systems with . In particular, by applyin…

Formation of localized states in dryland vegetation: Bifurcation structure and stability

P. Parra-Rivas, C. Fernandez-Oto

In this paper, we study theoretically the emergence of localized states of vegetation close to the onset of desertification. These states are formed through the locking of vegetati…

The 2019 Motile Active Matter Roadmap

Gerhard Gompper, Roland G. Winkler, Thomas Speck +34

Activity and autonomous motion are fundamental in living and engineering systems. This has stimulated the new field of active matter in recent years, which focuses on the physical…

Crystallization of the outer crust of a non-accreting neutron star

A. F. Fantina, S. De Ridder, N. Chamel +1

The interior of a neutron star (NS) is usually assumed to be made of cold catalyzed matter. However, the outer layers are unlikely to remain in full equilibrium during the formatio…

Nondegenerate Two-Photon Absorption in GaAs/AlGaAs Multiple Quantum Well Waveguides

Nicholas Cox, Junxiong Wei, Himansu Pattanaik +4

We present femtosecond pump-probe measurements of the nondegenerate (1960nm excitation and 1176--1326nm probe) two-photon absorption spectra of 8 nm GaAs/12nm Al$_{…

Crystallization of the inner crust of a neutron star and the influence of shell effects

T. Carreau, F. Gulminelli, N. Chamel +2

Context. In the cooling process of a non-accreting neutron star, the composition and properties of the crust are thought to be fixed at the finite temperature where nuclear reactio…

Floquet-engineering of nodal rings and nodal spheres and their characterization using the quantum metric

Grazia Salerno, Nathan Goldman, Giandomenico Palumbo

Semimetals exhibiting nodal lines or nodal surfaces represent a novel class of topological states of matter. While conventional Weyl semimetals exhibit momentum-space Dirac monopol…

Structure and colour in triangle-free graphs

N. R. Aravind, Stijn Cambie, Wouter Cames van Batenburg +3

Motivated by a recent conjecture of the first author, we prove that every properly coloured triangle-free graph of chromatic number contains a rainbow independent set of size $…

Searches for neutrinos from cosmic-ray interactions in the Sun using seven years of IceCube data

IceCube Collaboration, M. G. Aartsen, M. Ackermann +358

Cosmic-ray interactions with the solar atmosphere are expected to produce particle showers which in turn produce neutrinos from weak decays of mesons. These solar atmospheric neutr…

Minimal self-interacting dark matter models with light mediator

Thomas Hambye, Laurent Vanderheyden

The light mediator scenario of self-interacting dark matter is strongly constrained in many ways. After summarizing the various constraints, we discuss minimal options and models w…

First observation of a tau neutrino charged current interaction with charm production in the Opera experiment

N. Agafonova, A. Alexandrov, A. Anokhina +124

An event topology with two secondary vertices compatible with the decay of short-lived particles was found in the analysis of neutrino interactions in the Opera target. The observe…

Asymptotic dynamics of AdS gravity with two asymptotic regions

Marc Henneaux, Wout Merbis, Arash Ranjbar

The asymptotic dynamics of AdS gravity with two asymptotically anti-de Sitter regions is investigated, paying due attention to the zero modes, i.e., holonomies along non-contra…

Modeling of quasi-phase-matched cavity enhanced second harmonic generation

C. Mas Arabí, P. Parra-Rivas, C. Ciret +2

We propose a mean-field model to describe second harmonic generation in a resonator made of a material with zincblende crystalline structure. The model is obtained through an avera…

Erdős-Pósa from ball packing

Wouter Cames van Batenburg, Gwenaël Joret, Arthur Ulmer

A classic theorem of Erdős and Pósa (1965) states that every graph has either vertex-disjoint cycles or a set of vertices meeting all its cycles. While the standa…
