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…
On Schrödinger Operators Modified by Interactions
Kaya Güven Akbaş, Fatih Erman, O. Teoman Turgut
We study the spectral properties of a Schrödinger operator modified by interactions and show explicitly how the poles of the new Green's function are rearranged relative…
Rank One Perturbations Supported by Hybrid Geometries and Their Deformations
Fatih Erman, Sema Seymen, Osman Teoman Turgut
We study the hybrid type of rank one perturbations in and , where the perturbation supported by a circle/sphere is considered together with the delta p…
Relativistic Lee Model and its Resolvent Analysis
Yesukhei Jagvaral, O. Teoman Turgut, Meltem Ünel
We reexamine the relativistic 2+1 dimensional Lee model in light-front coordinates on flat space and on a space-time with a spatial section given by a compact manifold in the usual…
Born-Oppenheimer Approximation for a Simple Renormalizable System
Haci Akbas, O. Teoman Turgut
We discuss a simple singular system in two dimension, two heavy particles interacting with a light particle via an attractive contact interaction. Although intuitively clear the ac…
Born-Oppenheimer Approximation for a Singular System
Haci Akbas, O. Teoman Turgut
We discuss a simple singular system in one dimension, two heavy particles interacting with a light particle via an attractive contact interaction. It is natural to apply Born-Oppen…
