Local Casimir Energy For Solitons
Alfred Scharff Goldhaber, Andrei Litvintsev, Peter van Nieuwenhuizen
Direct calculation of the one-loop contributions to the energy density of bosonic and supersymmetric phi-to-the-fourth kinks exhibits: (1) Local mode regularization. Requiring the…
New results for the quantum supersymmetric kink
Alfred Scharff Goldhaber, Andrei Litvintsev, Peter van Nieuwenhuizen
We review our work on computations of the quantum corrections to the mass and the central charge of the susy kink. For the mass corrections, we find that the widely used momentum c…
Mode regularization of the susy sphaleron and kink: zero modes and discrete gauge symmetry
Alfred Scharff Goldhaber, Andrei Litvintsev, Peter van Nieuwenhuizen
To obtain the one-loop corrections to the mass of a kink by mode regularization, one may take one-half the result for the mass of a widely separated kink-antikink (or sphaleron) sy…
Once more on the BPS bound for the susy kink
Andrei Litvintsev, Peter van Nieuwenhuizen
We consider a new momentum cut-off scheme for sums over zero-point energies, containing an arbitrary function f(k) which interpolates smoothly between the zero-point energies of th…
The Supersymmetric Kink via Higher-Derivative and Momentum Cut-Off Regularization Schemes
Andrei Litvintsev
We study the supersymmetric kink with higher derivative and momentum cut-off regularization schemes. We introduce the new momentum cut-off regularization scheme which we call ``gen…
