Exact two-particle eigenstates in partially reduced QED
Jurij W. Darewych, Askold Duviryak
We consider a reformulation of QED in which covariant Green functions are used to solve for the electromagnetic field in terms of the fermion fields. It is shown that exact few-fer…
Exact spinor-scalar bound states in a QFT with scalar interactions
Volodymyr Shpytko, Jurij Darewych
We study two-particle systems in a model quantum field theory, in which scalar particles and spinor particles interact via a mediating scalar field. The Lagrangian of the model is…
A variational calculation of particle-antiparticle bound states in the scalar Yukawa model
Bingfeng Ding, Jurij Darewych
We consider particle-antiparticle bound states in the scalar Yukawa (Wick-Cutkosky) model. The variational method in the Hamiltonian formalism of quantum field theory is employed.…
Some exact solutions of reduced scalar Yukawa theory
Jurij W. Darewych
The scalar Yukawa model, in which a complex scalar field interact via a real scalar field, is reduced by using covariant Green functions. It is shown that exact few-particle eigens…
