Computation of unitary group for the Rashba spin-orbit coupled operator, with application to point-interactions
Rytis Jursenas
We compute an explicit formula for the one-parameter unitary group of the single-particle Rashba spin-orbit coupled operator in dimension three. As an application, we derive the fo…
Direct integral description of angulon
Rytis Jursenas
We propose a representation of angulon in which the angulon operator is decomposable relative to the field of Hilbert spaces over the probability measure space, and the probability…
A model for reducing the angulon operator
Rytis Jursenas, Mikhail Lemeshko
We propose a mathematical model for the recently introduced angulon. In our formulation, the angulon operator is decomposable relative to the field of Hilbert spaces over the proba…
Series expansion for the Fourier transform of a rational function in three dimensions
Rytis Jursenas
In Rashba-Dresselhaus spin-orbit coupled systems, the calculation of Green's function requires the knowledge of the inverse Fourier transform of rational function , wher…
Bound states of the spin-orbit coupled ultracold atom in a one-dimensional short-range potential
Rytis Jursenas, Julius Ruseckas
We solve the bound state problem for the Hamiltonian with the spin-orbit and the Raman coupling included. The Hamiltonian is perturbed by a one-dimensional short-range potential V…
The transformation of irreducible tensor operators under spherical functions
R. Jursenas, G. Merkelis
The irreducible tensor operators and their tensor products employing Racah algebra are studied. Transformation procedure of the coordinate system operators act on are introduced. T…
