Delta shock wave formation in the case of triangular hyperbolic system of conservation laws
V. G. Danilov, D. Mitrovic
We describe shock wave arising from continuous initial data in the case of triangular conservation law system arising from "generalized pressureless gas dynamics model". We use…
Elementary Charge Transfer Processes in a Superconductor-Ferromagnet Entangler
Jan Petter Morten, Daniel Huertas-Hernando, Wolfgang Belzig +1
We study the production of spatially separated entangled electrons in ferromagnetic leads from Cooper pairs in a superconducting lead. We give a complete description of the element…
Low regularity well-posedness of the Dirac-Klein-Gordon equations in one space dimension
Sigmund Selberg, Achenef Tesfahun
We extend recent results of S. Machihara and H. Pecher on low regularity well-posedness of the Dirac-Klein-Gordon (DKG) system in one dimension. Our proof, like that of Pecher, rel…
Stability properties of the collective stationary motion of self-propelling particles with conservative kinematic constraints
V. I. Ratushnaya, D. Bedeaux, V. L. Kulinskii +1
In our previous papers we proposed a continuum model for the dynamics of the systems of self-propelling particles with conservative kinematic constraints on the velocities. We have…
Magnetization damping in a local-density approximation
Hans Joakim Skadsem, Yaroslav Tserkovnyak, Arne Brataas +1
The linear response of itinerant transition metal ferromagnets to transverse magnetic fields is studied in a self-consistent adiabatic local-density approximation. The susceptibili…
Conductance spectra of ferromagnetic superconductors: Quantum transport in a ferromagnetic metal/non-unitary ferromagnetic superconductor junction
J. Linder, M. Grønsleth, A. Sudbø
Recent findings of superconductors that simultaneously exhibit multiple spontaneously broken symmetries, such as ferromagnetic order or lack of an inversion center and even combina…
Casimir Force on Real Materials - the Slab and Cavity Geometry
Simen A. Ellingsen, Iver Brevik
We analyse the potential of the geometry of a slab in a planar cavity for the purpose of Casimir force experiments. The force and its dependence on temperature, material properties…
Algebro-Geometric Finite-Gap Solutions of the Ablowitz-Ladik Hierarchy
Fritz Gesztesy, Helge Holden, Johanna Michor +1
We provide a detailed derivation of all complex-valued algebro-geometric finite-band solutions of the Ablowitz-Ladik hierarchy. In addition, we survey a recursive construction of t…
Uncertainty Principles and Vector Quantization
Yurii Lyubarskii, Roman Vershynin
Given a frame in C^n which satisfies a form of the uncertainty principle (as introduced by Candes and Tao), it is shown how to quickly convert the frame representation of every vec…
Spin transport in mesoscopic rings with inhomogeneous spin-orbit coupling
Yaroslav Tserkovnyak, Arne Brataas
We revisit the problem of electron transport through mesoscopic rings with spin-orbit (SO) interaction. In the well-known path-integral approach, the scattering states for a quasi-…
Fear and its implications for stock markets
Ingve Simonsen, Peter Toke Heden Ahlgren, Mogens H. Jensen +2
The value of stocks, indices and other assets, are examples of stochastic processes with unpredictable dynamics. In this paper, we discuss asymmetries in short term price movements…
Analytical Approach to Continuous and Intermittent Bottleneck Flows
Dirk Helbing, Anders Johansson, Joachim Mathiesen +2
We propose a many-particle-inspired theory for granular outflows from a hopper and for the escape dynamics through a bottleneck based on a continuity equation in polar coordinates.…
Vanishing Cosmological Constant in Modified Gauss-Bonnet Gravity with Conformal Anomaly
Iver Brevik, John Quiroga Hurtado
We consider dark energy cosmology in a de Sitter universe filled with quantum conformal matter. Our model represents a Gauss-Bonnet model of gravity with contributions from quantum…
A kernel for time series based on global alignments
Marco Cuturi, Jean-Philippe Vert, Oystein Birkenes +1
We propose in this paper a new family of kernels to handle times series, notably speech data, within the framework of kernel methods which includes popular algorithms such as the S…
Interplay between ferromagnetism and superconductivity in tunneling currents
M. S. Gronsleth, J. Linder, J. -M. Borven +1
We study tunneling currents in a model consisting of two non-unitary ferromagnetic spin-triplet superconductors separated by a thin insulating layer. We find a novel interplay betw…
Acyclic Calabi-Yau categories
Bernhard Keller, Idun Reiten
We show that an algebraic 2-Calabi-Yau triangulated category over an algebraically closed field is a cluster category if it contains a cluster tilting subcategory whose quiver has…
A New Approach to Nonrenormalizable Models
John R. Klauder
Nonrenormalizable quantum field theories require counterterms; and based on the hard-core interpretation of such interactions, it is initially argued, contrary to the standard view…
Towards a unification of HRT and SCOZA. Analysis of exactly solvable mean-spherical and generalized mean-spherical models
J. S. Hoye, A. Reiner
The hierarchical reference theory (HRT) and the self-consistent Ornstein-Zernike approximation (SCOZA) are two liquid state theories that both furnish a largely satisfactory descri…
Global geometry of planary 3-body motions
Wu-Yi Hsiang, Eldar Straume
In a recent paper (arXiv:math-ph/0609076) the authors investigated the basic global geometry of congruence moduli curves and shape curves of 3-body motions with vanishing angular m…
Infinite Horizon Noncooperative Differential Games with Non-Smooth Costs
Fabio S. Priuli
In the present paper, we consider a class of two players infinite horizon differential games, with piecewise smooth costs exponentially discounted in time. Through the analysis of…
Decay Processes in the Presence of Thin Superconducting Films
Per K. Rekdal, Bo-Sture K. Skagerstam
In a recent paper [Phys. Rev. Lett. 97, 070401 (2006)] the transition rate of magnetic spin-flip of a neutral two-level atom trapped in the vicinity of a thick superconducting body…
Derivation of the Ginzburg-Landau equations of a ferromagnetic p-wave superconductor
E. K. Dahl, A. Sudbo
We derive a Ginzburg-Landau free energy for a p-wave ferromagnetic superconductor. The starting point is a microscopic Hamiltonian including a spin generalised BCS term and a Heise…
Entropy of the Nordic electricity market: anomalous scaling, spikes, and mean-reversion
Josep Perello, Miquel Montero, Luigi Palatella +2
The electricity market is a very peculiar market due to the large variety of phenomena that can affect the spot price. However, this market still shows many typical features of oth…
Parametric resonance for antineutrino conversions using LSND best-fit results with a 3+1 flavor scheme
J. Linder
An analytical solution to a parametric resonance effect for antineutrinos in a 3+1 flavor (active+sterile) scheme using multiple non-adiabatic density shifts is presented. We deriv…
