Brownian Particles far from Equilibrium
Udo Erdmann, Werner Ebeling, Lutz Schimansky-Geier +1
We study a model of Brownian particles which are pumped with energy by means of a non-linear friction function, for which different types are discussed. A suitable expression for a…
Relativistic photoelectron spectra in the ionization of atoms by elliptically polarized light
J. Ortner
Relativistic tunnel ionization of atoms by intense, elliptically polarized light is considered. The relativistic version of the Landau-Dykhne formula is employed. The general analy…
BPS Amplitudes, Helicity Supertraces and Membranes in M-Theory
Bernard de Wit, Dieter Lust
We study BPS dominated loop amplitudes in M-theory on T^2. For this purpose we generalize the concept of helicity supertraces to nine spacetime dimensions. These traces distinguish…
Dynamic structure factor and collective excitations of neutral and Coulomb fluids
J. Ortner
The dynamic sructure factor as the basic quantity describing the collective excitations in a fluid is considered. We consider the cases of neutral and Coulombic fluids. The classic…
Semiclassical dynamics and time correlations in two-component plasmas
J. Ortner, I. Valuev, W. Ebeling
The semiclassical dynamics of a charged particle moving in a two-component plasma is considered using a corrected Kelbg pseudopotential. We employ the classical Nevanlinna-type the…
Relativistic semiclassical approach in strong-field nonlinear photoionization
J. Ortner, V. M. Rylyuk
Nonlinear relativistic ionization phenomena induced by a strong laser radiation with elliptically polarization are considered. The starting point is the classical relativistic acti…
Discrete Deformations in Type I Vacua
Carlo Angelantonj, Ralph Blumenhagen
We study supersymmetric orientifolds where the world-sheet parity transformation is combined with a conjugation of some compact complex coordinates. We investigate their T-duality…
Uphill Motion of Active Brownian Particles in Piecewise Linear Potentials
Frank Schweitzer, Benno Tilch, Werner Ebeling
We consider Brownian particles with the ability to take up energy from the environment, to store it in an internal depot, and to convert internal energy into kinetic energy of moti…
The topology of the Fermi surface of Bi2212 from angle resolved photoemission
M. S. Golden, S. V. Borisenko, S. Legner +9
We present a study of the topology of the normal state Fermi surface (FS) of the high Tc superconductor Bi2212 using angle-resolved photoemission. We present FS mapping experiments…
Directed motion of Brownian particles with internal energy depot
Benno Tilch, Frank Schweitzer, Werner Ebeling
A model of Brownian particles with the ability to take up energy from the environment, to store it in an internal depot, and to convert internal energy into kinetic energy of motio…
Supersymmetric M5-branes with H-field
D. Lust, A. Miemiec
In this paper we investigate the form of calibrated M5-branes in the presence of a nonvanishing 3-form field H. We discuss the influence of the H-field on the deformation of supers…
Exclusive semileptonic B decays to radially excited D mesons
D. Ebert, R. N. Faustov, V. O. Galkin
Exclusive semileptonic B decays to radially excited charmed mesons are investigated at the first order of the heavy quark expansion. The arising leading and subleading Isgur-Wise f…
Rigidity and Vanishing Theorems in K-Theory I
Kefeng Liu, Xiaonan Ma, Weiping Zhang
In this paper, we first establish a K-theory version of the equivariant family index theorem for a circle action, then use it to prove several rigidity and vanishing theorems on th…
On Open String Sigma-Model and Noncommutative Gauge Fields
Oleg Andreev, Harald Dorn
We consider the ordinary and noncommutative Dirac-Born-Infeld theories within the open string sigma-model. First, we propose a renormalization scheme, hybrid point splitting regula…
Fermionic correlators and zero-momentum modes in quenched lattice QED
I. L. Bogolubsky, V. K. Mitrjushkin, M. Müller-Preussker +2
For the Lorentz gauge the influence of various Gribov gauge copies on the fermion propagator is investigated in quenched compact lattice QED. Within the Coulomb phase besides doubl…
Electric microfield distribution in two-component plasmas. Theory and Simulations
J. Ortner, I. Valuev, W. Ebeling
The distribution of the electric microfield at a charged particle moving in a two-component plasma is calculated. The theoretical approximations are obtained via the parameter inte…
Horizontal and Vertical Five-Branes in Heterotic/F-Theory Duality
Bjorn Andreas, Gottfried Curio
We consider the heterotic string on an elliptic Calabi-Yau three-fold with five-branes wrapping curves in the base ('horizontal' curves) of the Calabi-Yau as well as some elliptic…
Symmetry breaking and other phenomena in the optimization of eigenvalues for composite membranes
S. Chanillo, D. Grieser, M. Imai +2
We consider the following eigenvalue optimization problem: Given a bounded domain and numbers , , find a subset of area for wh…
Modelling Migration and Economic Agglomeration with Active Brownian Particles
Frank Schweitzer
We propose a stochastic dynamic model of migration and economic aggregation in a system of employed (immobile) and unemployed (mobile) agents which respond to local wage gradients.…
