Quantum corrections to solitons and BPS saturation
A. Rebhan, P. van Nieuwenhuizen, R. Wimmer
We review our work of the past decade on one-loop quantum corrections to the mass M and central charge Z of solitons in supersymmetric field theories: the kink, the vortex, and the…
Nonvanishing quantum corrections to the mass and central charge of the N=2 vortex and BPS saturation
A. Rebhan, P. van Nieuwenhuizen, R. Wimmer
The one-loop quantum corrections to the mass and central charge of the N=2 vortex in 2+1 dimensions are determined using supersymmetry-preserving dimensional regularization by dime…
Comment on `One Loop Renormalization of Soliton Quantum Mass Corrections in 1+1 Dimensional Scalar Field Theory Models' (Phys. Lett. B542 (2002) 282 [hep-th/0206047])
A. Rebhan, P. van Nieuwenhuizen, R. Wimmer
We refute the claim that previous works on the one-loop quantum mass of solitons had incorrectly dropped a surface term from a partial integration. Rather, the paper quoted in the…
One-loop surface tensions of (supersymmetric) kink domain walls from dimensional regularization
A. Rebhan, P. van Nieuwenhuizen, R. Wimmer
We consider domain walls obtained by embedding the 1+1-dimensional -kink in higher dimensions. We show that a suitably adapted dimensional regularization method avoids the int…
No saturation of the quantum Bogomolnyi bound by two-dimensional supersymmetric solitons
A. Rebhan, P. van Nieuwenhuizen
We reanalyse the question whether the quantum Bogomolnyi bound is saturated in the two-dimensional supersymmetric kink and sine-Gordon models. Our starting point is the usual expre…
