One-loop results for kink and domain wall profiles at zero and finite temperature
Anton Rebhan, Andreas Schmitt, Peter van Nieuwenhuizen
Using dimensional regularization, we compute the one-loop quantum and thermal corrections to the profile of the bosonic 1+1-dimensional phi^4 kink, the sine-Gordon kink and the CP^…
Lectures on instantons
Stefan Vandoren, Peter van Nieuwenhuizen
This is a self-contained set of lecture notes on instantons in (super) Yang-Mills theory in four dimensions and in quantum mechanics. First the basics are derived from scratch: the…
Tensor calculus for supergravity on a manifold with boundary
Dmitry V. Belyaev, Peter van Nieuwenhuizen
Using the simple setting of 3D N=1 supergravity, we show how the tensor calculus of supergravity can be extended to manifolds with boundary. We present an extension of the standard…
Perturbative Quantum Corrections to the Supersymmetric CP^1 Kink with Twisted Mass
Christoph Mayrhofer, Anton Rebhan, Peter van Nieuwenhuizen +1
We present an explicit calculation of the one-loop quantum corrections to the mass and the two central charges of the kink solution of an N=(2,2) supersymmetric CP^1 model with twi…
Boundary Terms in Supergravity and Supersymmetry
P. van Nieuwenhuizen, A. Rebhan, D. V. Vassilevich +1
We begin with the simplest possible introduction to supergravity. Then we discuss its spin 3/2 stress tensor; these results are new. Next, we discuss boundary conditions on fields…
Quantum Mass and Central Charge of Supersymmetric Monopoles - Anomalies, current renormalization, and surface terms
Anton Rebhan, Peter van Nieuwenhuizen, Robert Wimmer
We calculate the one-loop quantum corrections to the mass and central charge of N=2 and N=4 supersymmetric monopoles in 3+1 dimensions. The corrections to the N=2 central charge ar…
