Casimir Problem in Spherical Dielectrics: A Quantum Statistical Mechanical Approach
I. Brevik, J. B. Aarseth, J. S. Høye
The Casimir mutual free energy F for a system of two dielectric concentric nonmagnetic spherical bodies is calculated, at arbitrary temperatures. Whereas F has recently been evalua…
Complexes of modules over exceptional Lie superalgebras and
Victor G. Kac, Alexei Rudakov
In this paper complexes of generalized Verma modules over the infinite-dimensional exceptional Lie superalgebras and are constructed and studied.
Thermodynamic Properties of the 2N-Piece Relativistic String
Iver Brevik, Andrei A. Bytsenko, Roger Sollie
The thermodynamic free energy F(β) is calculated for a gas consisting of the transverse oscillations of a piecewise uniform bosonic string. The string consists of 2N parts of equal…
Quasi-Metric Relativity
Dag Østvang
This is a survey of a new type of relativistic space-time framework; the so-called quasi-metric framework. The basic geometric structure underlying quasi-metric relativity is quasi…
Fermion-pairing on a square lattice in extreme magnetic fields
S. Mo, A. Sudbo
We consider the Cooper-problem on a two-dimensional, square lattice with a uniform, perpendicular magnetic field. Only rational flux fractions are considered. An extended (real-spa…
Radiation forces on an absorbing micrometer-sized sphere in an evanescent field
I. Brevik, T. A. Sivertsen, E. Almaas
The vertical radiation force on an absorbing micrometer-sized dielectric sphere situated in an evanescent field is calculated, using electromagnetic wave theory. The present work i…
On the Cardy-Verlinde Entropy Formula in Viscous Cosmology
I. Brevik, S. D. Odintsov
The results of the paper of Verlinde [hep-th/0008140], discussing the holographic principle in a radiation dominated universe, are extended when allowing the cosmic fluid to posses…
Self-consistent Ornstein-Zernike approximation for three-dimensional spins
D. Pini, J. S. Hoye, G. Stell
An Ornstein-Zernike approximation for the two-body correlation function embodying thermodynamic consistency is applied to a system of classical Heisenberg spins on a three-dimensio…
The order of the metal to superconductor transition
S. Mo, J. Hove, A. Sudbo
We present results from large-scale Monte Carlo simulations on the full Ginzburg-Landau (GL) model, including fluctuations in the amplitude and the phase of the matter-field, as we…
Specific Heat upon Aqueous Unfolding of the Protein Interior: A Theoretical Approach
Audun Bakk, Johan S. Hoye, Alex Hansen
We study theoretically the thermodynamics, over a broad temperature range (5 C to 125 C), related to hydrated water upon protein unfolding. The hydration effect is modeled as inter…
Light Rays at Optical Black Holes in Moving Media
I. Brevik, G. Halnes
Light experiences a non-uniformly moving medium as an effective gravitational field, endowed with an effective metric tensor , being the re…
Design of one-dimensional Lambertian diffusers of light
A. A. Maradudin, I. Simonsen, T. A. Leskova +1
We describe a method for designing a one-dimensional random surface that acts as a Lambertian diffuser. The method is tested by means of rigorous computer simulations and is shown…
Profit Profiles in Correlated Markets
Ingve Simonsen, Kim Sneppen
We consider a financial market where the asset price follows a fractional Brownian motion. We introduce a family of investment strategies, and quantify profit possibilities for bot…
Noise and Order in Cavity Quantum Electrodynamics
Per Rekdal, Bo-Sture Skagerstam
In this paper we investigate the various aspects of noise and order in the micromaser system. In particular, we study the effect of adding fluctuations to the atom cavity transit t…
Heat Capacity of Protein Folding
Audun Bakk, Johan S. Hoye, Alex Hansen
We construct a Hamiltonian for a single domain protein where the contact enthalpy and the chain entropy decrease linearly with the number of native contacts. The hydration effect u…
A new relation between pressure and fractional flow in two-phase flow in porous media
Henning Arendt Knudsen, Alex Hansen
We study average flow properties in porous media using a two-dimensional network simulator. It models the dynamics of two-phase immiscible bulk flow where film flow can be neglecte…
Modellization of hydraulic fracturing of porous materials
F. Tzschichholz, M. Wangen
We review microstructural fracture growth models suitable for the study of hydraulic fracture processes in disordered porous materials and present some basic results. It is shown t…
Casimir Effect for a Dielectric Wedge
I. Brevik, K. Pettersen
The Casimir effect is considered for a wedge with opening angle , with perfectly conducting walls, when the interior region is filled with an isotropic and nondispersive medium…
