Neutron specific heat in the crust of neutron stars from the nuclear band theory

Nicolas Chamel, Jérôme Margueron, Elias Khan

The inner crust of neutron stars, formed of a crystal lattice of uclear clusters immersed in a sea of unbound neutrons, may be the nique example of periodic nuclear systems. We hav…

The Plane-Width of Graphs

Marcin Kaminski, Paul Medvedev, Martin Milanic

Map vertices of a graph to (not necessarily distinct) points of the plane so that two adjacent vertices are mapped at least a unit distance apart. The plane-width of a graph is the…

Statistical properties of time-reversible triangular maps of the square

Vasileios Basios, Gian Luigi Forti, Thomas Gilbert

Time reversal symmetric triangular maps of the unit square are introduced with the property that the time evolution of one of their two variables is determined by a piecewise expan…

Duality and integrability: Electromagnetism, linearized gravity and massless higher spin gauge fields as bi-Hamiltonian systems

Glenn Barnich, Cedric Troessaert

In the reduced phase space of electromagnetism, the generator of duality rotations in the usual Poisson bracket is shown to generate Maxwell's equations in a second, much simpler P…

The Klebanov-Strassler model with massive dynamical flavors

Francesco Bigazzi, Aldo L. Cotrone, Angel Paredes +1

We present a fully backreacted D3-D7 supergravity solution dual to the Klebanov-Strassler cascading gauge theory coupled to a large number of massive dynamical flavors in the Venez…

Isospectrality of conventional and new extended potentials, second-order supersymmetry and role of PT symmetry

B. Bagchi, C. Quesne, R. Roychoudhury

We develop a systematic approach to construct novel completely solvable rational potentials. Second-order supersymmetric quantum mechanics dictates the latter to be isospectral to…

Testing large-scale (an)isotropy of ultra-high energy cosmic rays

Hylke B. J. Koers, Peter Tinyakov

We present a simple yet powerful method to test models of cosmic-ray (CR) origin using the distribution of CR arrival directions. The method is statistically unambiguous in the sen…

Diagnoses to unravel secular hydrodynamical processes in rotating main sequence stars

T. Decressin, S. Mathis, A. Palacios +4

(Abridged) We present a detailed analysis of the main physical processes responsible for the transport of angular momentum and chemical species in the radiative regions of rotating…

Stackelberg Network Pricing is Hard to Approximate

Gwenaël Joret

In the Stackelberg Network Pricing problem, one has to assign tariffs to a certain subset of the arcs of a given transportation network. The aim is to maximize the amount paid by t…

The core helium flash revisited: II. Two and three-dimensional hydrodynamic simulations

M. Mocak, E. Mueller, A. Weiss +1

We study turbulent convection during the core helium flash close to its peak by comparing the results of two and three-dimensional hydrodynamic simulations. We use a multidimension…

Large-amplitude Love waves

Elizabete Rodrigues Ferreira, Philippe Boulanger, Michel Destrade

In the context of the finite elasticity theory, we consider a model for compressible solids called 'compressible neo-Hookean material'. We show how finite-amplitude inhomogeneous p…

Fluctuation theorem for currents in open quantum systems

David Andrieux, Pierre Gaspard, Takaaki Monnai +1

A quantum-mechanical framework is set up to describe the full counting statistics of particles flowing between reservoirs in an open system under time-dependent driving. A symmetry…

Reconciling MOND and dark matter?

Jean-Philippe Bruneton, Stefano Liberati, Lorenzo Sindoni +1

Observations of galaxies suggest a one-to-one analytic relation between the inferred gravity of dark matter at any radius and the enclosed baryonic mass, a relation summarized by M…

A No-Go Theorem for Gaussian Quantum Error Correction

Julien Niset, Jaromir Fiurasek, Nicolas J. Cerf

It is proven that Gaussian operations are of no use for protecting Gaussian states against Gaussian errors in quantum communication protocols. Specifically, we introduce a new quan…

Boosting Taub-NUT to a BPS NUT-wave

Riccardo Argurio, François Dehouck, Laurent Houart

The boosted Taub-NUT metric with zero ADM mass is shown to possess a dual momentum in the direction of the boost giving credit to the existence of another 4-vector K_μin linearized…
