Hydrodynamics of fundamental matter
Francesco Bigazzi, Aldo L. Cotrone, Javier Tarrio
First and second order transport coefficients are calculated for the strongly coupled N=4 SYM plasma coupled to massless fundamental matter in the Veneziano limit. The results, inc…
Bohr Hamiltonian with deformation-dependent mass term
Dennis Bonatsos, P. Georgoudis, D. Lenis +2
The Bohr Hamiltonian describing the collective motion of atomic nuclei is modified by allowing the mass to depend on the nuclear deformation. Exact analytical expressions are deriv…
Sugawara-type constraints in hyperbolic coset models
Thibault Damour, Axel Kleinschmidt, Hermann Nicolai
In the conjectured correspondence between supergravity and geodesic models on infinite-dimensional hyperbolic coset spaces, and E10/K(E10) in particular, the constraints play a cen…
Integrability of Five Dimensional Minimal Supergravity and Charged Rotating Black Holes
Pau Figueras, Ella Jamsin, Jorge V. Rocha +1
We explore the integrability of five-dimensional minimal supergravity in the presence of three commuting Killing vectors. We argue that to see the integrability structure of the th…
Weak Chaos and the "Melting Transition" in a Confined Microplasma System
Chris Antonopoulos, Vasileios Basios, Tassos Bountis
We present results demonstrating the occurrence of changes in the collective dynamics of a Hamiltonian system which describes a confined microplasma characterized by long--range Co…
A dynamical inconsistency of Horava gravity
Marc Henneaux, Axel Kleinschmidt, Gustavo Lucena Gómez
The dynamical consistency of the non-projectable version of Horava gravity is investigated by focusing on the asymptotically flat case. It is argued that for generic solutions of t…
Impact of nonlocal interactions in dissipative systems: towards minimal-sized localized structures
L. Gelens, G. Van der Sande, P. Tassin +5
In order to investigate the size limit on spatial localized structures in a nonlinear system, we explore the impact of linear nonlocality on their domains of existence and stabilit…
One-electron atomic-molecular ions containing Lithium in a strong magnetic field
H. Olivares Pilón, D. Baye, A. V. Turbiner +1
The one-electron Li-containing Coulomb systems of atomic type and molecular type , and are studied in the presence of a strong magn…
XML Multidimensional Modelling and Querying
Serge Boucher, Boris Verhaegen, Esteban Zimányi
As XML becomes ubiquitous and XML storage and processing becomes more efficient, the range of use cases for these technologies widens daily. One promising area is the integration o…
The k-in-a-path problem for claw-free graphs
Jiri Fiala, Marcin Kaminski, Bernard Lidicky +1
Testing whether there is an induced path in a graph spanning k given vertices is already NP-complete in general graphs when k=3. We show how to solve this problem in polynomial tim…
Intense Gamma-Ray Lines from Hidden Vector Dark Matter Decay
Chiara Arina, Thomas Hambye, Alejandro Ibarra +1
Scenarios with hidden, spontaneously broken, non-abelian gauge groups contain a natural dark matter candidate, the hidden vector, whose longevity is due to an accidental custodial…
Tight Lower Bounds on the Sizes of Symmetric Extensions of Permutahedra and Similar Results
Kanstantsin Pashkovich
It is well known that the permutahedron Pi_n has 2^n-2 facets. The Birkhoff polytope provides a symmetric extended formulation of Pi_n of size Theta(n^2). Recently, Goemans describ…
Reconciling leptogenesis with observable mu --> e gamma rates
Steve Blanchet, Thomas Hambye, Francois-Xavier Josse-Michaux
We perform a detailed analysis of thermal leptogenesis in the framework of seesaw models which approximately conserve lepton number. These models are known to allow for large Yukaw…
Green's function method for strength function in three-body continuum
Y. Suzuki, W. Horiuchi, D. Baye
Practical methods to compute dipole strengths for a three-body system by using a discretized continuum are analyzed. New techniques involving Green's function are developed, either…
Dark matter stability and unification without supersymmetry
Michele Frigerio, Thomas Hambye
In the absence of low energy supersymmetry, we show that (a) the dark matter particle alone at the TeV scale can improve gauge coupling unification, raising the unification scale u…
Patterns of Soft Masses from General Semi-Direct Gauge Mediation
Riccardo Argurio, Matteo Bertolini, Gabriele Ferretti +1
We give a general formulation of semi-direct gauge mediation of supersymmetry breaking where the messengers interact with the hidden sector only through a weakly gauged group. Usin…
Some Algebraic Aspects of Half-BPS Bound States in M-Theory
Laurent Houart, Axel Kleinschmidt, Josef Lindman Hörnlund
We revisit non-marginal half-BPS solutions of M-theory in the framework of the possible existence of an underlying E11 Kac-Moody symmetry. In this context, non-marginal BPS solutio…
Generalized BIons in M-theory
Chethan Krishnan
In string theory, stacks of D1-branes can expand into intersecting D3-branes. These configurations are called (generalized) BIons. We show how the analogous constructions in M-theo…
Current data on the globular cluster Palomar 14 are not inconsistent with MOND
Gianfranco Gentile, Benoit Famaey, Garry W. Angus +1
Certain types of globular clusters have the very important property that the predictions for their kinematics in the Newtonian and modified Newtonian dynamics (MOND) contexts are d…
Extending the search for neutrino point sources with IceCube above the horizon
The IceCube Collaboration, R. Abbasi
Point source searches with the IceCube neutrino telescope have been restricted to one hemisphere, due to the exclusive selection of upward going events as a way of rejecting the at…
Further explorations of Skyrme-Hartree-Fock-Bogoliubov mass formulas. XI: Stabilizing neutron stars against a ferromagnetic collapse
N. Chamel, S. Goriely, J. M. Pearson
We construct a new Hartree-Fock-Bogoliubov (HFB) mass model, labeled HFB-18, with a generalized Skyrme force. The additional terms that we have introduced into the force are densit…
Phase behavior of a confined nano-droplet in the grand-canonical ensemble: the reverse liquid-vapor transition
James F. Lutsko, Julien Laidet, Patrick Grosfils
The equilibrium density distribution and thermodynamic properties of a Lennard-Jones fluid confined to nano-sized spherical cavities at constant chemical potential was determined u…
Effects of the variation of fundamental constants on Pop III stellar evolution
Sylvia Ekstrom, Alain Coc, Pierre Descouvemont +4
A variation of the fundamental constants is expected to affect the thermonuclear rates important for stellar nucleosynthesis. In particular, because of the very small resonant ener…
Isometries and Construction of Permutation Arrays
Mathieu Bogaerts
An (n,d)-permutation code is a subset C of Sym(n) such that the Hamming distance d_H between any two distinct elements of C is at least equal to d. In this paper, we use the charac…
