We analyze the thermodynamic behavior of the generalized scalar Yukawa model,
composed of a complex scalar field interacting with scalar and vector fields. Finite-size …

We study the thermodynamic behavior of the generalized scalar Yukawa model, composed
of a complex scalar field interacting with scalar and vector fields. Thermal effects are treated …

The variational method in a reformulated Hamiltonian formalism of quantum
electrodynamics is used to derive relativistic wave equations for a system consisting of n …

The recent observation of a positronium molecule (e− e+ e− e+) by Cassidy and Mills (DB
Cassidy and AP Mills 2007 Nature (London) 449 195) raises interest in other (fermionic) …

A generalization of the scalar Yukawa model to include many'flavors' of scalar particles and
antiparticles is considered. The variational method within the Hamiltonian formalism of …

In this paper, we investigate the thermodynamics of a Yukawa-like model, constituted of a
complex scalar field interacting with real scalar and vector fields, in the presence of an …

In this work, we investigate the thermodynamic behavior of the generalized scalar Yukawa
model, composed of a complex scalar field interacting with real scalar and vector fields. In …

We use the Hamiltonian formalism of quantum field theory and the variational basis-state
method to derive relativistic three-body wave equations for scalar particles interacting via a …

The Hamiltonian formalism of quantum field theory and the variational methods in a
reformulated model have been used to investigate the influence of retardation effects or …

The variational method within the Hamiltonian formalism of quantum field theory has been
used in order to investigate the effect of virtual pairs for four-body scalar systems consisting …
