Exact Methods for Self Interacting Neutrinos
Y. Pehlivan, A. B. Balantekin, Toshitaka Kajino
The effective many-body Hamiltonian which describes vacuum oscillations and self interactions of neutrinos in a two flavor mixing scheme under the single angle approximation has th…
Symmetry and Supersymmetry in Nuclear Pairing: Exact Solutions
A. B. Balantekin, Y. Pehlivan
Pairing plays a crucial role in nuclear spectra and attempts to describe it has a long history in nuclear physics. The limiting case in which all single particle states are degener…
An Exactly Solvable Supersymmetric Model of Semimagic Nuclei
A. B. Balantekin, N. Guven, Y. Pehlivan
A simple model of nucleons coupled to angular momentum zero (s-pairs) occupying the valance shell of a semi-magic nuclei is considered. The model has a separable, orbit dependent p…
Solutions of Nuclear Pairing
A. B. Balantekin, Y. Pehlivan
We give the exact solution of orbit dependent nuclear pairing problem between two non-degenerate energy levels using the Bethe ansatz technique. Our solution reduces to previously…
Supersymmetry and Nuclear Pairing
A. B. Balantekin, Y. Pehlivan
We show that nuclear pairing Hamiltonian exhibits supersymmetry in the strong-coupling limit. The underlying supersymmetric quantum mechanical structure explains the degeneracies b…
Spectra and Symmetry in Nuclear Pairing
A. B. Balantekin, J. H. de Jesus, Y. Pehlivan
We apply the algebraic Bethe ansatz technique to the nuclear pairing problem with orbit dependent coupling constants and degenerate single particle energy levels. We find the exact…
