Kepler Eclipsing Binary Stars. VII. The Catalog of Eclipsing Binaries Found in the Entire Kepler Data-Set

Brian Kirk, Kyle Conroy, Andrej Prša +47

The primary Kepler Mission provided nearly continuous monitoring of ~200,000 objects with unprecedented photometric precision. We present the final catalog of eclipsing binary syst…

On twists of modules over non-commutative Iwasawa algebras

Somnath Jha, Tadashi Ochiai, Gergely Zábrádi

It is well known that, for any finitely generated torsion module M over the Iwasawa algebra Z_p [[Γ ]], where Γ is isomorphic to Z_p, there exists a continuous p-adic character ρ o…

On endomorphisms of the Einstein gyrogroup in arbitrary dimension

Péter E. Frenkel

We determine the automorphisms and the continuous endomorphisms of the Einstein gyrogroup in arbitrary dimension. This generalizes a recent result of Lajos Molnár and Dániel Virosz…

An analytic hydrodynamical model of rotating 3D expansion in heavy-ion collisions

M. I. Nagy, T. Csörgő

A new exact and analytic solution of non-relativistic fireball hydrodynamics is presented. It describes an expanding triaxial ellipsoid that rotates around one of its principal axe…

Truncated Hilbert space approach to the 2d $ϕ^{4}$ theory

Z. Bajnok, M. Lajer

We apply the massive analogue of the truncated conformal space approach to study the two dimensional $ϕ^{4}$ theory in finite volume. We focus on the broken phase and determine the…

Exploring the spectroscopic diversity of type Ia supernovae with DRACULA: a machine learning approach

Michele Sasdelli, E. E. O. Ishida, R. Vilalta +8

The existence of multiple subclasses of type Ia supernovae (SNeIa) has been the subject of great debate in the last decade. One major challenge inevitably met when trying to infer…

Lattice QCD on Non-Orientable Manifolds

Simon Mages, Balint C. Toth, Szabolcs Borsanyi +3

A common problem in lattice QCD simulations on the torus is the extremely long autocorrelation time of the topological charge, when one approaches the continuum limit. The reason i…

Magnetic field oscillations of the critical current in long ballistic graphene Josephson junctions

Péter Rakyta, Andor Kormányos, József Cserti

We study the Josephson current in long ballistic superconductor-monolayer graphene-superconductor junctions. As a first step, we have developed an efficient computational approach…

Shear viscosity over entropy density ratio with extended quasi-particles

M. Horváth, A. Jakovác

We consider an effective field theory description of beyond-quasi-particle excitations aiming to associate the transport properties of the system with the spectral density of state…

Red giant masses and ages derived from carbon and nitrogen abundances

Marie Martig, Morgan Fouesneau, Hans-Walter Rix +7

We show that the masses of red giant stars can be well predicted from their photospheric carbon and nitrogen abundances, in conjunction with their spectroscopic stellar labels log…

Double self-Kerr scheme for optical Schrödinger-cat state preparation

P. Adam, Z. Darázs, T. Kiss +1

We propose a scheme to prepare optical Schrödinger-cat states in a traveling wave setting. Two states are similarly prepared via the self-Kerr effect and after mixing them, one mod…

Clear evidence for the presence of second-generation asymptotic giant branch stars in metal-poor Galactic globular clusters

D. A. Garcia-Hernandez, Sz. Meszaros, M. Monelli +5

Galactic globular clusters (GCs) are known to host multiple stellar populations: a first generation with a chemical pattern typical of halo field stars and a second generation (SG)…

Running coupling of the sextet composite Higgs model

Zoltan Fodor, Kieran Holland, Julius Kuti +3

The scale-dependent renormalized coupling of SU(3) gauge theory coupled to Nf = 2 flavors of massless Dirac flavors in the sextet representation is presented in the range 0 < g^2 <…

Observables and initial conditions for rotating and expanding fireballs with spheroidal symmetry

T. Csorgo, M. I. Nagy, I. F. Barna

Utilizing a recently found class of exact, analytic rotating solutions of non-relativistic fireball hydrodynamics, we calculate analytically the single-particle spectra, the ellipt…

Chromatic roots and limits of dense graphs

Peter Csikvari, Peter E. Frenkel, Jan Hladky +1

In this short note we observe that recent results of Abert and Hubai and of Csikvari and Frenkel about Benjamini--Schramm continuity of the holomorphic moments of the roots of the…

Entanglement negativity in two-dimensional free lattice models

Viktor Eisler, Zoltán Zimborás

We study the scaling properties of the ground-state entanglement between finite subsystems of infinite two-dimensional free lattice models, as measured by the logarithmic negativit…

Chip-firing based methods in the Riemann--Roch theory of directed graphs

Bálint Hujter, Lilla Tóthmérész

Baker and Norine proved a Riemann--Roch theorem for divisors on undirected graphs. The notions of graph divisor theory are in duality with the notions of the chip-firing game of Bj…

Algebraic Bethe Ansatz for O(2N) sigma models with integrable diagonal boundaries

Tamas Gombor, Laszlo Palla

The finite volume problem of O(2N) sigma models with integrable diagonal boundaries on a finite interval is investigated. The double row transfer matrix is diagonalized by Algebrai…

A Comprehensive Study of the Kepler Triples via Eclipse Timing

T. Borkovits, T. Hajdu, J. Sztakovics +4

We produce and analyze eclipse time variation (ETV) curves for some 2600 Kepler binaries. We find good to excellent evidence for a third body in 222 systems via either the light-tr…

Static quark-antiquark pair free energy and screening masses: continuum results at the QCD physical point

Szabolcs Borsanyi, Zoltan Fodor, Sandor D. Katz +3

We study the correlators of Polyakov loops, and the corresponding gauge invariant free energy of a static quark-antiquark pair in 2+1 flavor QCD at finite temperature. Our simulati…
