Quantum corrections to mass and central charge of supersymmetric solitons
Alfred Scharff Goldhaber, Anton Rebhan, Peter van Nieuwenhuizen +1
We review some recent developments in the subject of quantum corrections to soliton mass and central charge. We consider in particular approaches which use local densities for thes…
Quantum corrections to the mass and central charge of solitons in 1+1 dimensions
A. S. Goldhaber, A. Rebhan, P. van Nieuwenhuizen +1
We first discuss how the longstanding confusion in the literature concerning one-loop quantum corrections to 1+1 dimensional solitons has finally been resolved. Then we use 't Hoof…
Clash of discrete symmetries for the supersymmetric kink on a circle
Alfred Scharff Goldhaber, Anton Rebhan, Peter van Nieuwenhuizen +1
We consider the N=1 supersymmetric kink on a circle, i.e., on a finite interval with boundary or transition conditions which are locally invisible. For Majorana fermions, the singl…
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…
Dual Confinement of Grand Unified Monopoles?
Alfred Scharff Goldhaber
A simple formal computation, and a variation on an old thought experiment, both indicate that QCD with light quarks may confine fundamental color magnetic charges, giving an explic…
First Are Last Fractional-Charge Solitons
Alfred S. Goldhaber
Jackiw and Rebbi found two types of intrinsically stable or `fundamental' soliton (kinks in 1+1 D and magnetic monopoles in 3+1 D) which can carry pieces of elementary-particle cha…
Hairs on the Unicorn: Fine Structure of Monopoles and Other Solitons
Alfred S. Goldhaber
Intrinsically stable or `fundamental' solitons may be decorated with conserved charges which are pieces of those carried by elementary particles in the same medium. These `hairs' a…
Aharonov-Bohm Problem for Spin-One
M. L. Horner, Alfred S. Goldhaber
The basic AB problem is to determine how an unshielded tube of magnetic flux affects arbitrarily long-wavelength charged particles impinging on it. For spin-1 at almost all …
AB and Berry phases for a quantum cloud of charge
Y. Aharonov, S. Coleman, A. S. Goldhaber +5
We investigate the phase accumulated by a charged particle in an extended quantum state as it encircles one or more magnetic fluxons, each carrying half a flux unit. A simple, esse…
Solitons with integer fermion number
Alfred S. Goldhaber
Necessary and sufficient conditions are found for any object in dimensions to have integer rather than fractional fermion number. Nontrivial examples include the Jackiw-Rebbi…
