Does the Transverse Electric Zero Mode Contribute to the Casimir Effect for a Metal?
J. S. Hoye, I. Brevik, J. B. Aarseth +1
The finite temperature Casimir free energy, entropy, and internal energy are considered anew for a conventional parallel-plate configuration, in the light of current discussions in…
Asymmetric Optical Radiation Pressure Effects on Liquid Interfaces Under Intense Illumination
Alexis Casner, Jean-Pierre Delville, Iver Brevik
Deformations of horizontal liquid interfaces by optical radiation pressure are generally expected to display similar behaviors whatever the direction of propagation of the exciting…
Dynamic stiffness of spin valves
Yaroslav Tserkovnyak, Arne Brataas, Gerrit E. W. Bauer
The dynamics of the magnetic order parameters of ferromagnet/normal-metal/ferromagnet spin valves and isolated ferromagnets may be very different. We investigate the role of the no…
Modularity and Extreme Edges of the Internet
Kasper Astrup Eriksen, Ingve Simonsen, Sergei Maslov +1
We study the spectral properties of a diffusion process taking place on the Internet network focusing on the slowest decaying modes. These modes allow us to identify an underlying…
Microflares in accretion disks
V. Krishan, S. Ramadurai, P. J. Wiita
We have investigated the phenomenon of explosive chromospheric evaporation from an accretion disk as a mechanism for fast variability in accreting sources such as low mass X-ray bi…
Andreev-Bashkin effect and knot solitons in interacting mixture of a charged and a neutral superfuids with possible releveance for neutron stars
Egor Babaev
We discuss a mixture of interacting a neutral and a charged Bose condensates, which is supposed being realized in interior of neutron stars in form of coexistent neutron superfluid…
Spectral Analysis of Darboux Transformations for the Focusing NLS Hierarchy
Radu C. Cascaval, Fritz Gesztesy, Helge Holden +1
We study Darboux transformations associated with the focusing nonlinear Schrödinger equation (NLS_-) and their effect on spectral properties of the underlying Lax operator. The lat…
Dynamic exchange coupling in magnetic bilayers
Bret Heinrich, Yaroslav Tserkovnyak, Georg Woltersdorf +3
A long-ranged dynamic interaction between ferromagnetic films separated by normal-metal spacers is reported, which is communicated by nonequilibrium spin currents. It is measured b…
Kosterlitz-Thouless-like deconfinement mechanism in the 2+1 dimensional Abelian Higgs model
Hagen Kleinert, Flavio S. Nogueira, Asle Sudbo
We point out that the permanent confinement in a compact 2+1-dimensional U(1) Abelian Higgs model is destroyed by matter fields in the fundamental representation. The deconfinement…
Real-Valued Algebro-Geometric Solutions of the Camassa--Holm hierarchy
Fritz Gesztesy, Helge Holden
We provide a treatment of real-valued, smooth, and bounded algebro-geometric solutions of the Camassa--Holm (CH) hierarchy and describe the associated isospectral torus. We also di…
Cosmic Evolution and Primordial Black Hole Evaporation
I. Brevik, G. Halnes
A cosmological model in which primordial black holes (PBHs) are present in the cosmic fluid at some instant t=t_0 is investigated. The time t_0 is naturally identified with the end…
Dynamic Rearrangements and Packing Regimes in Randomly Deposited Two-Dimensional Granular Beds
I. Bratberg, F. Radjai, A. Hansen
We study the structural properties of two-dimensional granular packings prepared by random deposition from a source line. We consider a class of random ballistic deposition models…
Knots in Charged Polymers
Paul G. Dommersnes, Yacov Kantor, Mehran Kardar
The interplay of topological constraints and Coulomb interactions in static and dynamic properties of charged polymers is investigated by numerical simulations and scaling argument…
Time delay as a key to Apoptosis Induction in the p53 Network
G. Tiana, M. H. Jensen, K. Sneppen
A feedback mechanism that involves the proteins p53 and mdm2, induces cell death as a controled response to severe DNA damage. A minimal model for this mechanism demonstrates that…
Criticality in the 2+1-dimensional compact Higgs model and fractionalized insulators
A. Sudbø, E. Smørgrav, J. Smiseth +2
We use a novel method of computing the third moment M_3 of the action of the 2+1-dimensional compact Higgs model in the adjoint representation with q=2 to extract correlation lengt…
Infinite dimensional representations of canonical algebras
Idun Reiten, Claus Michael Ringel
The aim of this paper is to extend the structure theory for infinitely generated modules over tame hereditary algebras to the more general case of modules over concealed canonical…
Generic differential equation for fractional flow of steady two-phase flow in porous media
Henning Arendt Knudsen, Alex Hansen
We report on generic relations between fractional flow and pressure in steady two-phase flow in porous media. The main result is a differential equation for fractional flow as a fu…
Specificity and stability in topology of protein networks
Sergei Maslov, Kim Sneppen
Molecular networks guide the biochemistry of a living cell on multiple levels: its metabolic and signalling pathways are shaped by the network of interacting proteins, whose produc…
Pattern Detection in Complex Networks: Correlation Profile of the Internet
Sergei Maslov, Kim Sneppen, Alexei Zaliznyak
A general scheme for detecting and analyzing topological patterns in large complex networks is presented. In this scheme the network in question is compared with its properly rando…
Cardy-Verlinde Entropy Formula in the Presence of a General Cosmological State Equation
I. Brevik
As recently found by Youm [hep-th/0201268], the entropy of the universe will no longer be expressible in the conventional Cardy-Verlinde form if one relaxes the radiation dominance…
Localization of Gravity on Brane Embedded in and
Iver Brevik, Kazuo Ghoroku, Sergei D. Odintsov +1
We address the localization of gravity on the Friedmann-Robertson-Walker type brane embedded in either or bulk space,and derive two definite limits between which…
Domain wall creep in epitaxial ferroelectric Pb(Zr0.2Ti0.8)O3 thin films
T. Tybell, P. Paruch, T. Giamarchi +1
Ferroelectric switching and nanoscale domain dynamics were investigated using atomic force microscopy on monocrystalline Pb(Zr0.2Ti0.8)O3 thin films. Measurements of domain size ve…
Tightness of slip-linked polymer chains
Ralf Metzler, Andreas Hanke, Paul G. Dommersnes +2
We study the interplay between entropy and topological constraints for a polymer chain in which sliding rings (slip-links) enforce pair contacts between monomers. These slip-links…
Entropy Bounds in Geometries
Iver Brevik, Kimball A. Milton, Sergei D. Odintsov
Exact calculations are given for the Casimir energy for various fields in geometry. The Green's function method naturally gives a result in a form convenient in the h…
