Macroscopic limit cycle via pure noise-induced phase transition
R. Kawai, X. Sailer, L. Schimansky-Geier +1
Bistability generated via a pure noise-induced phase transition is reexamined from the view of bifurcations in macroscopic cumulant dynamics. It allows an analytical study of the p…
D=4, N=2 Gauged Supergravity in the Presence of Tensor Multiplets
Riccardo D'Auria, Gianguido Dall'Agata, Luca Sommovigo +1
Using superspace techniques we construct the general theory describing D=4, N=2 supergravity coupled to an arbitrary number of vector and scalar--tensor multiplets. The scalar mani…
A Gravity Dual of Chiral Symmetry Breaking
J. Babington, J. Erdmenger, N. Evans +2
We establish a holographic description of chiral symmetry breaking for a particular confining large N non-supersymmetric gauge theory with matter in the fundamental representation.…
Proper weak-coupling approach to the periodic s-d(f) exchange model
T. Hickel, W. Nolting
The periodic s-d(f) exchange model is characterized by a wide variety of interesting applications, a simple mathematical structure and a limited number of reliable approximations w…
Dephasing in Quantum Dots: Quadratic Coupling to Acoustic Phonons
E. A. Muljarov, R. Zimmermann
A microscopic theory of optical transitions in quantum dots with carrier-phonon interaction is developed. Virtual transitions into higher confined states with acoustic phonon assis…
Purely infinite C*-algebras: ideal-preserving zero homotopies
Eberhard Kirchberg, Mikael Rordam
We show that if A is a separable, nuclear, O_infty-absorbing (or strongly purely infinite) C*-algebra, which is homotopic to zero in an ideal-system preserving way, then A is the i…
General chiral gauge theories
Werner Kerler
Only requiring that Dirac operators decribing massless fermions on the lattice decompose into Weyl operators we arrive at a large class of them. After deriving general relations fr…
Estimating Driving Forces of Nonstationary Time Series with Slow Feature Analysis
Laurenz Wiskott
Slow feature analysis (SFA) is a new technique for extracting slowly varying features from a quickly varying signal. It is shown here that SFA can be applied to nonstationary time…
Loop Equation in Two-dimensional Noncommutative Yang-Mills Theory
Harald Dorn, Alessandro Torrielli
The classical analysis of Kazakov and Kostov of the Makeenko-Migdal loop equation in two-dimensional gauge theory leads to usual partial differential equations with respect to the…
N=1 geometries for M-theory and type IIA strings with fluxes
Gianguido Dall'Agata, Nikolaos Prezas
We derive a set of necessary and sufficient conditions for obtaining N=1 backgrounds of M-theory and type IIA strings in the presence of fluxes. Our metrics are warped products of…
On details of the thermodynamical derivation of the Ginsburg--Landau equations
A. V. Dmitriev, W. Nolting
We examine the procedure of thermodynamical derivation of the Ginsburg--Landau equation for current, which is given unclear and contradictory interpretations in existing textbooks.…
E11 and Spheric Vacuum Solutions of Eleven- and Ten dimensional Supergravity Theories
Igor Schnakenburg, Andre Miemiec
In view of the newly conjectured Kac-Moody symmetries of supergravity theories placed in eleven and ten dimensions, the relation between these symmetry groups and possible compacti…
The nucleon mass in N_f=2 lattice QCD: finite size effects from chiral perturbation theory
A. Ali Khan, T. Bakeyev, M. Göckeler +8
In the framework of relativistic SU(2)_f baryon chiral perturbation theory we calculate the volume dependence of the nucleon mass up to and including O(p^4). Since the parameters i…
Lattice simulations of 2-colour QCD with Wilson fermions
Jon-Ivar Skullerud, Shinji Ejiri, Simon Hands +1
We report on the status of our simulations of two-colour QCD with two flavours of Wilson quarks, at nonzero chemical potential and diquark source. Preliminary results are presented…
SO(3) vs. SU(2) Yang-Mills theory on the lattice: an investigation at non-zero temperature
A. Barresi, G. Burgio, M. Muller-Preussker
The adjoint SU(2) lattice gauge theory in 3+1 dimensions with the Wilson plaquette action modified by a Z(2) monopole suppression term is reinvestigated with special emphasis on th…
Correlation Functions and Vertex Operators of Liouville Theory
George Jorjadze, Gerhard Weigt
We calculate correlation functions for vertex operators with negative integer exponentials of a periodic Liouville field, and derive the general case by continuing them as distribu…
The photon propagator in compact QED_{2+1}: the effect of wrapping Dirac strings
M. N. Chernodub, E. -M. Ilgenfritz, A. Schiller
We discuss the influence of closed Dirac strings on the photon propagator in the Landau gauge emerging from a study of the compact U(1) gauge model in 2+1 dimensions. This gauge al…
Kinetic Integrals in the Kinetic Theory of dissipative gases
Thorsten Poeschel, Nikolai V. Brilliantov
The kinetic theory of gases, including Granular Gases, is based on the Boltzmann equation. Many properties of the gas, from the characteristics of the velocity distribution functio…
Stochastic resonance in a non Markovian discrete state model for excitable systems
T. Prager, L. Schimansky-Geier
We study a non Markovian three state model, subjected to an external periodic signal. This model is intended to describe an excitable systems with periodical driving. In the limit…
Higher order loop equations for A_r and D_r quiver matrix models
Stefano Chiantese, Albrecht Klemm, Ingo Runkel
We use free boson techniques to investigate A-D-E-quiver matrix models. Certain higher spin fields in the free boson formulation give rise to higher order loop equations valid at f…
