BCS Gap Equation on Riemannian Manifolds: A Heat Kernel Analysis
Levent Akant, Emine Ertugrul, O. Teoman Turgut
In this paper, we investigate the Bardeen-Cooper-Schrieffer (BCS) theory of superconductivity formulated on a three dimensional Riemannian manifold. We derive the gap equation in t…
Renormalization of One-Dimensional Semirelativistic Bosons with Contact Interactions
Fatih Erman, O. Teoman Turgut
We study one-dimensional spinless bosons with semirelativistic spinless-Salpeter dispersion and attractive pairwise contact interactions. Because the dispersion becomes linear at l…
Perturbation Theory for Time-Dependent Point Interactions with Discrete Spectrum
Kaya Güven Akbaş, Fatih Erman, O. Teoman Turgut
We develop a perturbative framework for time-dependent point interactions in quantum systems with purely discrete unperturbed spectrum. In two and three dimensions the point intera…
