Strictly isospectral supersymmetry and Schroedinger general zero modes
L. J. Boya, H. Rosu, A. J. Segui-Santonja +1
The connection between the strictly isospectral construction in supersymmetric quantum mechanics and the general zero mode solutions of the Schroedinger equation is explained by in…
Supersymmetric one-parameter strict isospectrality for the attractive delta potentials
L. J. Boya, H. C. Rosu, A. J. Segui-Santonja +2
The Schrödinger equation with attractive delta potential has been previously studied in the supersymmetric quantum mechanical approach by a number of authors, but they all used onl…
Topological charges and the genus of surfaces
Luis J. Boya, Antonio J. Segui-Santonja
We show that the topological charge of the n-soliton solution of the sine-Gordon equation n is related to the genus g > 1 of a constant negative curvature compact surface described…
A modified Schwinger's formula for the Casimir effect
M. V. Cougo-Pinto, C. Farina, Antonio J. Segui-Santonja
After briefly reviewing how the (proper-time) Schwinger's formula works for computing the Casimir energy in the case of "scalar electrodynamics" where the boundary conditions are d…
Motion and Trajectories of Particles Around Three-Dimensional Black Holes
C. Farina, J. Gamboa, A. J. Segui-Santonja
The motion of relativistic particles around three dimensional black holes following the Hamilton-Jacobi formalism is studied. It follows that the Hamilton-Jacobi equation can be se…
