Comment on "Supersymmetry in the half-oscillator - revisited"
Ashok Das, S. Pernice
We point out the flaw in the analysis of Gangopadhyaya and Mallow, hep-th/0206133, where it is claimed that supersymmetry is broken in the SUSY half-oscillator, even with a regular…
Supersymmetry and Singular Potentials
Ashok Das, Sergio A. Pernice
The breaking of supersymmetry due to singular potentials in supersymmetric quantum mechanics is critically analyzed. It is shown that, when properly regularized, these potentials r…
Higher Dimensional SUSY Quantum Mechanics
Ashok Das, Sergio. A. Pernice
Higher dimensional supersymmetric quantum mechanics is studied. General properties of the two dimensional case are presented. For three spatial dimesions or higher, a spin structur…
``Induced'' Super-Symmetry Breaking with a Vanishing Vacuum Energy
Ashok Das, Sergio A. Pernice
A new mechanism for symmetry breaking is proposed which naturally avoids the constraints following from the usual theorems of symmetry breaking. In the context of super-symmetry, f…
On the Divergence of Perturbation Theory. Steps Towards a Convergent Series
S. A. Pernice, G. Oleaga
The mechanism underlying the divergence of perturbation theory is exposed. This is done through a detailed study of the violation of the hypothesis of the Dominated Convergence The…
Nonperturbative Renormalon Structure of Infrared Unstable Theories
A. Duncan, S. Pernice
The properties of a generalized version of the Borel Transform in infrared unstable theories with dynamical mass generation are studied. The reconstruction of the nonperturbative s…
