On the similarity of boundary triples of symmetric operators in Krein spaces

Rytis Jursenas

It is a classical result that the Weyl function of a simple symmetric operator in a Hilbert space determines a boundary triple uniquely up to unitary equivalence. We generalize thi…

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…

A note on the spectrum of a two-particle Rashba Hamiltonian

Rytis Jursenas

In a series of recent papers it was shown that, when the attractive s-wave interaction is dominant, the spin-orbit coupled fermions form a bound state. Attributed to a convenient m…

Application of symbolic programming for atomic many-body theory

Rytis Jursenas, Gintaras Merkelis

In the present paper by using Mathematica system a symbolic programming method for generation of the expressions of the expansion terms of atomic stationary perturbation theory (PT…
