Low-cost fermions in classical field simulations [PDF]

, 2008
We discuss the possible extension of the bosonic classical field theory simulations to include fermions. This problem has been addressed in terms of the inhomogeneous mean field approximation by Aarts and Smit.

L’éducation aux médias en Allemagne : quelles singularités ?

Revue Française des Sciences de l’Information et de la Communication, 2018
In the course of our research on media literacy, we noted that there are some differences between French and German education policies on how media use of young people should be regulated.

Sphaleron Effects Near the Critical Temperature

, 1994
We discuss one-loop radiative corrections to the sphaleron-induced baryon number-violating transition rate near the electroweak phase transition in the standard model.

Effect of the scalar condensate on the linear gauge field response in the Abelian Higgs model [PDF]

, 2001
The effective equations of motion for low-frequency mean gauge fields in the Abelian Higgs model are investigated in the presence of a scalar condensate, near the high temperature equilibrium.

Self-consistent bounces in two dimensions

, 2004
We compute bounce solutions describing false vacuum decay in a Phi**4 model in two dimensions in the Hartree approximation, thus going beyond the usual one-loop corrections to the decay rate.

Vilem Flusser, the 21st Century and the Interactive Technologies [PDF]

, 2012
When Vilem Flusser developed his idea of the technical \ud images, he could not foresee how far the technical development of producing images would go. The technical image has become an important part of the perception of the public, eventhough it still ...

An application of the renormalization group to the calculation of the vacuum decay rate in flat and curved space-time

, 2007
I show that an application of renormalization group arguments may lead to significant corrections to the vacuum decay rate for phase transitions in flat and curved space-time.

Quantum back-reaction of the superpartners in a large-N supersymmetric hybrid model

, 2007
We study the supersymmetric hybrid model near and after the end of inflation. As usual, we reduce the model to a purely scalar hybrid model on the level of the classical fields. But on the level of quantum fluctuations and their backreaction we take into
