Parton distributions in the chiral quark model: a continuum computation [PDF]

, 2000
We compute the parton distributions for the chiral quark model. We present a new technique for performing such computations based on Green functions. This approach avoids a discretization of the spectrum.

Gauge Fields Out-Of-Equilibrium: A Gauge Invariant Formulation and the Coulomb Gauge

, 2001
We study the abelian Higgs model out-of-equilibrium in two different approaches, a gauge invariant formulation, proposed by Boyanovsky et al. \cite{Boyanovsky:1996dc} and in the Coulomb gauge.

Effective action for bubble nucleation rates [PDF]

, 2001
We develop a method to calculate the prefactor in the expression for the bubble nucleation rate. A fermion with Yukawa coupling is considered where a step potential can be used as a good approximation in the thin wall limit.

One-Loop Corrections to Bubble Nucleation Rate at Finite Temperature

, 1993
We present an evaluation of the 1-loop prefactor in the lifetime of a metastable state which decays at finite temperature by bubble nucleation. Such a state is considered in one-component phi^4 model in three space dimensions. The calculation serves as a

Editorial: Medienpädagogik und Erwachsenenbildung

MedienPädagogik: Zeitschrift für Theorie und Praxis der Medienbildung, 2018
Anliegen des vorliegenden Themenheftes ist es, das Verhältnis von Medienpädagogik und Erwachsenenbildung zu diskutieren, als auch die Aufmerksamkeit beider Bereiche im Sinne möglicher gegenseitiger Impulse aufeinander zu lenken. Medienpädagogik kann «als

Nonequilibrium evolution and symmetry structure of the large-N $\Phi^4$ model at finite temperature

, 2000
We consider the large-N $\Phi^4$ theory with spontaneously broken symmetry at finite temperature. We study, in the large-N limit, quantum states which are characterized by a time dependent, spatially homogenous expectation value of one of the field ...

One-loop corrections to the Nielsen-Olesen vortex: collective oscillations

, 2010
We connect the translation modes of the instanton in the two-dimensional Abelian Higgs model with local translations of the vortex of the related model in (3+1) dimensions, the Nielsen-Olesen vortex.
