Interaction of a non-relativistic particle with a spin with a pseudoscalar field
A. Shurgaia
A non-relativistic model of a moving fermion in a pseudoscalar field is investigated using N. N. Bogolyubov's method. The invariance properties are rigorously described. The energi…

Two-dimensional model of interaction of a non-relativistic particle with scalar mesons in the strong coupling limit
A. Shurgaia
Bogolyubov transformations are introduced into the nonrelativistic model of particle interaction with scalar mesons. Within the framework of the generalized Hamiltonian formalism d…
