Casimir Force on a Micrometer Sphere in a Dip: Proposal of an Experiment
I. Brevik, E. K. Dahl, G. O. Myhr
The attractive Casimir force acting on a micrometer-sphere suspended in a spherical dip, close to the wall, is discussed. This setup is in principle directly accessible to experime…
The problem of small and large scale fields in the solar dynamo
A. Brandenburg, N. E. L. Haugen, P. J. Käpylä +1
Three closely related stumbling blocks of solar mean field dynamo theory are discussed: how dominant are the small scale fields, how is the alpha effect quenched, and whether magne…
Instanton correlators and phase transitions in two- and three-dimensional logarithmic plasmas
K. Borkje, S. Kragset, A. Sudbo
The existence of a discontinuity in the inverse dielectric constant of the two-dimensional Coulomb gas is demonstrated on purely numerical grounds. This is done by expanding the fr…
Hydrodynamic and hydromagnetic energy spectra from large eddy simulations
N. E. L. Haugen, A. Brandenburg
Direct and large eddy simulations of hydrodynamic and hydromagnetic turbulence have been performed in an attempt to isolate artifacts from real and possibly asymptotic features in…
The onset of a small-scale turbulent dynamo at low magnetic Prandtl numbers
A. A. Schekochihin, N. E. L. Haugen, A. Brandenburg +3
We study numerically the dependence of the critical magnetic Reynolds number Rmc for the turbulent small-scale dynamo on the hydrodynamic Reynolds number Re. The turbulence is stat…
Field- and temperature induced topological phase transitions in the three-dimensional -component London superconductor
J. Smiseth, E. Smorgrav, E. Babaev +1
The phase diagram and critical properties of the -component London superconductor are studied both analytically and through large-scale Monte-Carlo simulations in dimens…
Semi-Meissner state and neither type-I nor type-II superconductivity in multicomponent systems
Egor Babaev, J. Martin Speight
Traditionally, superconductors are categorized as type-I or type-II. Type-I superconductors support only Meissner and normal states, while type-II superconductors form magnetic vor…
Vortex sub-lattice melting in a two-component superconductor
Eivind Smorgrav, Jo Smiseth, Egor Babaev +1
We consider the vortex matter in a three-dimensional two-component superconductor with individually conserved condensates with different bare phase stiffnesses in a finite magnetic…
A superconductor to superfluid phase transition in liquid metallic hydrogen
Egor Babaev, Asle Sudbo, N. W. Ashcroft
Although hydrogen is the simplest of atoms, it does not form the simplest of solids or liquids. Quantum effects in these phases are considerable (a consequence of the light proton…
On the Temperature Dependence of the Casimir Effect
I. Brevik, J. B. Aarseth, J. S. Høye +1
The temperature dependence of the Casimir force between a real metallic plate and a metallic sphere is analyzed on the basis of optical data concerning the dispersion relation of m…
Non-Linear Deformations of Liquid-Liquid Interfaces Induced by Electromagnetic Radiation Pressure
Aslak Hallanger, Iver Brevik, Skjalg Haaland +1
The idea of working with a near-critical phase-separated liquid mixture whereby the surface tension becomes weak, has recently made the field of laser manipulation of liquid interf…
Nano-mechanical magnetization reversal
Alexey A. Kovalev, Gerrit E. W. Bauer, Arne Brataas
The dynamics of the ferromagnetic order parameter in thin magnetic films is strongly affected by the magnetomechanical coupling at certain resonance frequencies. By solving the equ…
Models for the irreducible representation of a Heisenberg group
T. Digernes, V. S. Varadarajan
In its most general formulation a quantum kinematical system is described by a Heisenberg group; the "configuration space" in this case corresponds to a maximal isotropic subgroup.…
On error bounds for monotone approximation schemes for multi-dimensional Isaacs equations
Espen R. Jakobsen
Recently, Krylov, Barles, and Jakobsen developed the theory for estimating errors of monotone approximation schemes for the Bellman equation (a convex Isaacs equation). In this pap…
Spin Hall effects in diffusive normal metals
R. V. Shchelushkin, Arne Brataas
We consider spin and charge flow in normal metals. We employ the Keldysh formalism to find transport equations in the presence of spin-orbit interaction, interaction with magnetic…
Electromagnetic wave scattering from conducting self-affine surfaces : An analytic and numerical study
Ingve Simonsen, Damien Vandembroucq, Stephane Roux
We derive an analytical expression for the scattering of a scalar wave from a perfectly conducting self-affine one dimensional surface in the framework of the Kirchhoff approximati…
Nonlocal magnetization dynamics in ferromagnetic heterostructures
Yaroslav Tserkovnyak, Arne Brataas, Gerrit E. W. Bauer +1
Two complementary effects modify the GHz magnetization dynamics of nanoscale heterostructures of ferromagnetic and normal materials relative to those of the isolated magnetic const…
Quantum Mechanics of a Particle with Two Magnetic Impurities
Stefan Mashkevich, Jan Myrheim, Stéphane Ouvry
A two-dimensional quantum mechanical system consisting of a particle coupled to two magnetic impurities of different strengths, in a harmonic potential, is considered. Topological…
An associative network with spatially organized connectivity
Yasser Roudi, Alessandro Treves
We investigate the properties of an autoassociative network of threshold-linear units whose synaptic connectivity is spatially structured and asymmetric. Since the methods of equil…
Finite Hochschild cohomology without finite global dimension
R. -O. Buchweitz, E. L. Green, D. Madsen +1
Dieter Happel asked the following question: If the -th Hochschild cohomology group of a finite dimensional algebra over a field vanishes for all sufficiently large , is t…
Spontaneous-Symmetry-Breaking Mechanism of Adiabatic Pumping
Yaroslav Tserkovnyak, Arne Brataas
We consider heterostructures consisting of regions with a continuous symmetry in contact with regions wherein the symmetry is spontaneously broken. The low-frequency dynamics of th…
Virial Coefficients of Multispecies Anyons
Stefan Mashkevich, Jan Myrheim, Kaare Olaussen
A path integral formalism for multispecies anyons is introduced, whereby partition functions are expressed in terms of generating functions of winding number probability distributi…
Metastable states in the planar 2d XY model and dissipation in superfluid flow
G. G. Batrouni
We use the Metropolis algorithm to study the stability of superfluid flow in a model system, namely the two-dimensional planar XY model. Flow properties are examined by studying th…

Ivan Saika-Voivod, Francesco Sciortino, Tor Grande +1
We evaluate the phase diagram of the ``BKS'' potential [Van Beest, Kramer and van Santen, Phys. Rev. Lett. 64, 1955 (1990)], a model of silica widely used in molecular dynamics (MD…
