Fragmentation in Frustrated Magnets -- A review
E. Lhotel, L. D. C. Jaubert, P. C. W. Holdsworth
Spin liquids are exotic phases of matter that often support emergent gauge fields and quasi-particle excitations. While spin liquids are commonly known for remaining disordered, th…
Three-dimensional ferrimagnetic ground state of triangular-lattice system Ca3Co2O6
Santanu De, V. R. Reddy, A. Banerjee
High temperature one-dimensional (1D) ferromagnetic (FM) chains in Ca3Co2O6 spin system are subjected to a magnetic field and temperature induced first order phase transition (FOPT…
Coarse geometry of Hecke pairs and the Baum-Connes conjecture
Clément Dell'Aiera
We study Hecke pairs using the coarse geometry of their coset space and their Schlichting completion. We prove new stability results for the Baum-Connes and the Novikov conjectures…
The MUSE-Faint survey. III. No large dark-matter cores and no significant tidal stripping in ultra-faint dwarf galaxies
Sebastiaan L. Zoutendijk, Mariana P. Júlio, Jarle Brinchmann +8
[Abridged] Aims. The lowest-mass galaxies, ultra-faint dwarf galaxies, promise unparalleled constraints on how feedback regulates galaxy formation, and on the small-scale matter po…
Eager Functions as Processes
Adrien Durier, Daniel Hirschkoff, Davide Sangiorgi
We study Milner's encoding of the call-by-value -calculus into the -calculus. We show that, by tuning the encoding to two subcalculi of the -calculus (Internal and Asy…
Second generation star formation in globular clusters of different masses
A. Yaghoobi, F. Calura, J. Rosdahl +1
By means of three-dimensional hydrodynamical simulations, we investigate the formation of second generation (SG) stars in young globular clusters of different masses. We consider c…
Eccentric debris disc morphologies I: exploring the origin of apocentre and pericentre glows in face-on debris discs
Elliot M. Lynch, Joshua B. Lovell
The location of surface brightness maxima (e.g. apocentre and pericentre glow) in eccentric debris discs are often used to infer the underlying orbits of the dust and planetesimals…
A systematic study of the escape of LyC and Ly photons from star-forming, magnetized turbulent clouds
Taysun Kimm, Rebekka Bieri, Sam Geen +4
Understanding the escape of Lyman continuum (LyC) and Lyman (Ly) photons from giant molecular clouds (GMCs) is crucial if we are to study the reionization of the Universe an…
Does relativistic cosmology software handle emergent volume evolution?
Justyna Borkowska, Boudewijn F. Roukema
Several software packages for relativistic cosmological simulations that do not fully implement the Einstein equation have recently been developed. Two of the free-licensed ones ar…
Holographic Evidence for Non-Supersymmetric Conformal Manifolds
Alfredo Giambrone, Adolfo Guarino, Emanuel Malek +3
We provide the first holographic evidence for the existence of a non-supersymmetric conformal manifold arising from exactly marginal but supersymmetry-breaking deformations of a su…
List types for resource aware languages: an implicit name approach
Silvia Ghilezan, Jelena Ivetić, Pierre Lescanne +1
A novel formalisation of variable control in languages with implicit names based on de Bruijn indices is presented. We design and implement three languages: first, a restricted lan…
How do CPT-like symmetries shape the stability of geophysical flows?
Tomos W. David, Pierre Delplace, Antoine Venaille
We examine the role discrete symmetries, time-reversal and mirror symmetries, play in the context of geophysical waves and instabilities. By looking at three special cases from the…
On Up-to Context Techniques in the -calculus
Enguerrand Prebet
We present a variant of the theory of compatible functions on relations, due to Sangiorgi and Pous. We show that the up-to context proof technique for bisimulation is compatible in…
Measurable fractional spin for quantum Hall quasiparticles on the disk
Tommaso Comparin, Alvin Opler, Elia Macaluso +3
We study the spin of the localised quasiparticle excitations of lowest-Landau-level quantum Hall states defined on a disk. The spin that we propose satisfies the spin-statistics re…
Controlling Wasserstein Distances by Kernel Norms with Application to Compressive Statistical Learning
Titouan Vayer, Rémi Gribonval
Comparing probability distributions is at the crux of many machine learning algorithms. Maximum Mean Discrepancies (MMD) and Wasserstein distances are two classes of distances betw…
Quantifying Non-Stationarity with Information Theory
Carlos Granero-Belinchon, Stéphane G. Roux, Nicolas B. Garnier
We introduce an index based on information theory to quantify the stationarity of a stochastic process.The index compares on the one hand the information contained in the increment…
Anomalies in the topology of the temperature fluctuations in the cosmic microwave background: An analysis of the and data releases
Pratyush Pranav
We present a multi-scale topological analysis of the temperature fluctuation maps from the NPIPE and FFP10 datasets, invoking relative homology to account for the analysis in the p…
HI observations of the MATLAS dwarf and ultra-diffuse galaxies
Melina Poulain, Francine R. Marleau, Rebecca Habas +8
The presence of HI gas in galaxies is inextricably linked to their morphology and evolution. This paper aims to understand the HI content of the already identified 2210 dwarfs loca…
A prediction for anisotropies in the nearby Hubble flow
Asta Heinesen, Hayley J. Macpherson
We assess the dominant low-redshift anisotropic signatures in the distance-redshift relation and redshift drift signals. We adopt general-relativistic irrotational dust models allo…
Non-orientable order and non-Abelian response in frustrated metamaterials
Xiaofei Guo, Marcelo Guzman, David Carpentier +2
From atomic crystals to bird flocks, most forms of order are captured by the concept of spontaneous symmetry breaking. This paradigm was challenged by the discovery of topological…
Algebraic infection of charge correlations of a classical electrolyte at the critical point of the liquid-gas transition
Angel Alastuey, Subir Das
We consider a classical Two-Component Plasma analog of the Restricted Primitive Model of electrolyte, where the hard-core interaction is replaced by a soft differentiable potential…
Quantized Berry winding from an emergent symmetry
Thibaud Louvet, Pierre Delplace, Mark Oliver Goerbig +1
Linear crossing of energy bands occur in a wide variety of materials. In this paper we address the question of the quantization of the Berry winding characterizing the topology of…
Effects of radiative losses on the relativistic jets of high-mass microquasars
A. Charlet, R. Walder, A. Marcowith +3
Context. Relativistic jets are ubiquitous in astrophysics. High Mass Microquasars (HMMQs) are useful labs to study such jets, as they are relatively close and evolve over observabl…
PHANGS-MUSE: the HII region luminosity function of local star-forming galaxies
Francesco Santoro, Kathryn Kreckel, Francesco Belfiore +30
We use an unprecedented sample of about 23,000 HII regions detected at an average physical resolution of 67pc in the PHANGS-MUSE sample to study the extragalactic HII region Ha lum…
