Description of all complex geodesics in the symmetrized bidisc
P. Pflug, W. Zwonek
In the paper we find effective formulas for the complex geodesics in the symmetrized bidisc.
Entire curves avoiding given sets in C^n
Nikolai Nikolov, Peter Pflug
Let be a proper closed subset of and at most countable (). We give conditions of and , under which there…
On automorphisms of the symmetrized bidisc
Marek Jarnicki, Peter Pflug
We characterize the group for the symmetrized bidisc .
Complete Weight Enumerators of Generalized Doubly-Even Self-Dual Codes
Gabriele Nebe, H. -G. Quebbemann, E. M. Rains +1
For any q which is a power of 2 we describe a finite subgroup of the group of invertible complex q by q matrices under which the complete weight enumerators of generalized doubly-e…
On large deviation properties of Erdos-Renyi random graphs
Andreas Engel, Rémi Monasson, Alexander K. Hartmann
We show that large deviation properties of Erdös-Rényi random graphs can be derived from the free energy of the -state Potts model of statistical mechanics. More precisely the L…
Platonic Sphalerons
B. Kleihaus, J. Kunz, K. Myklevoll
We construct sphaleron solutions in Weinberg-Salam theory, which possess only discrete symmetries. Related to rational maps of degree N, these sphalerons carry baryon number Q_B=N/…
Stochastic analysis of surface roughness
M. Waechter, F. Riess, H. Kantz +1
For the characterization of surface height profiles we present a new stochastic approach which is based on the theory of Markov processes. With this analysis we achieve a character…
On different cascade-speeds for longitudinal and transverse velocity increments
M. Siefert, J. Peinke
We address the problem of differences between longitudinal and transverse velocity increments in isotropic small scale turbulence. The relationship of these two quantities is analy…
On the upper semicontinuity of the Wu metric
Marek Jarnicki, Peter Pflug
We discuss continuity and upper semicontinuity of the Wu pseudometric.
The non-Markovian quantum behavior of open systems: An exact Monte Carlo method employing stochastic product states
Heinz-Peter Breuer
It is shown that the exact dynamics of a composite quantum system can be represented through a pair of product states which evolve according to a Markovian random jump process. Thi…
Enhancement of Noise-induced Escape through the Existence of a Chaotic Saddle
Suso Kraut, Ulrike Feudel
We study the noise-induced escape process in a prototype dissipative nonequilibrium system, the Ikeda map. In the presence of a chaotic saddle embedded in the basin of attraction o…
Multistability, noise and attractor-hopping: The crucial role of chaotic saddles
Suso Kraut, Ulrike Feudel
We investigate the hopping dynamics between different attractors in a multistable system under the influence of noise. Using symbolic dynamics we find a sudden increase of dynamica…
Properties of non-BPS SU(3) monopoles
Yasha Shnir
This paper is concerned with magnetic monopole solutions of SU(3) Yang-Mills-Higgs system beyond the Bogomol'nyi-Prasad-Sommerfield limit. The different SU(2) embeddings, which cor…
Exact quantum jump approach to open systems in Bosonic and spin baths
Heinz-Peter Breuer
A general method is developed which enables the exact treatment of the non-Markovian quantum dynamics of open systems through a Monte Carlo simulation technique. The method is base…
Collective coordinates of the Skyrme model coupled with fermions
Ya. Shnir
The problem of construction of fiber bundle over the moduli space of the Skyrme model is considered. We analyse an extension of the original Skyrme model which includes the minimal…
Monopole--Antimonopole Chains
B. Kleihaus, J. Kunz, Ya. Shnir
We present new static axially symmetric solutions of SU(2) Yang-Mills-Higgs theory, representing chains of monopoles and antimonopoles in static equilibrium. They correspond to sad…
Rotating Dilaton Black Holes with Hair
B. Kleihaus, J. Kunz, F. Navarro-Lerida
We consider stationary rotating black holes in SU(2) Einstein-Yang-Mills theory, coupled to a dilaton. The black holes possess non-trivial non-Abelian electric and magnetic fields…
Quantum jumps and entropy production
Heinz-Peter Breuer
The irreversible motion of an open quantum system can be represented through an ensemble of state vectors following a stochastic dynamics with piecewise deterministic paths. It is…
Non-Fickian diffusion and tau approximation from numerical turbulence
Axel Brandenburg, Petri Käpylä, Amjed Mohammed
Evidence for non-Fickian diffusion of a passive scalar is presented using direct simulations of homogeneous isotropic turbulence. The results compare favorably with an explicitly t…
Distance bounds for convolutional codes and some optimal codes
Heide Gluesing-Luerssen, Wiland Schmale
After a discussion of the Griesmer and Heller bound for the distance of a convolutional code we present several codes with various parameters, over various fields, and meeting the…
Concepts and methods in the theory of open quantum systems
Heinz-Peter Breuer, Francesco Petruccione
The central physical concepts and mathematical techniques used in the theory of open quantum systems are reviewed. Particular emphasis is laid on the interrelations of apparently d…
On the involutions fixing the class of a lattice
Heinz-Georg Quebbemann, Eric M. Rains
With any integral lattice Λin n-dimensional euclidean space we associate an elementary abelian 2-group I(λ) whose elements represent parts of the dual lattice that are similar to Λ…
