Third-order relativistic dynamics: classical spinning particle travelling in a plane

Matsyuk, R. (Condensed Matter Physics, 1998)

Mathisson’s ‘new mechanics’ of a relativistic spinning particle is shown to follow, in the case of planar motion, from only general requirements of relativistic invariance and of the dependence on third order derivatives ...
Isotropic forms of dynamics in the relativistic direct interaction theory

Duviryak, A.; Shpytko, V.; Tretyak, V. (Condensed Matter Physics, 1998)

The Lagrangian relativistic direct interaction theory in the various forms of dynamics is formulated and its connections with the Fokker-type action theory and with the constrained Hamiltonian mechanics are established. The ...
Connecting the potential theory to the quantum field theory

Sazdjian, H. (Condensed Matter Physics, 1998)

A constraint theory is applied to two-particle systems to construct Poincare´ invariant wave equations with interaction potentials. The latter can be determined in the quantum field theory from Feynman diagrams. ...
Squared Weyl and Dirac fields with the Sommers-Sen connection associated with V³₄ distributions

Pelykh, V. (Condensed Matter Physics, 1998)

Generalization of the Sommers–Sen spinor connection for spinor fields, associated with the distribution V³₄ is made and on its basis the equations for Weyl and Dirac null vector fields on complexificated V³₄ are ...
Gravitational spin-orbit interaction: criteria of increase

Plyatsko, R. (Condensed Matter Physics, 1998)

The gravitational spin-orbit interaction in the region of the ultrarelativistic orbital velocity of a spinning test particle in the Schwarzschild field is investigated on the basis of the Mathisson-Papapetrou equations. ...
Quasi-relativistic center-of-mass variables in applications

Gaida, R.; Tretyak, V.; Yaremko, Yu. (Condensed Matter Physics, 1998)

Collective center-of-mass variables are introduced in the Lagrangian formalism of the relativistic classical mechanics of directly interacting particles. It is shown that the transition to the Hamiltonian formalism leads ...
Classical relativistic spin particles

Llosa, J. (Condensed Matter Physics, 1998)

Relativistic spin particles are approached from the stand point of Hamiltonian actions of Poincare group on itself. The several possible solutions are classified and realizations are given in terms of Dirac’s constraints ...
On single-time methods in relativistic gravity dynamics

Opanasyuk, Yu.A. (Condensed Matter Physics, 1998)

A short outline of revived methods of an action-at-a-distance description of interacting particles is given. A new approach to the problem of motion in relativistic gravity is discussed. The approach makes an essential ...
On relativistic models in the equilibrium statistical mechanics

Tretyak, V. (Condensed Matter Physics, 1998)

Relativistic effects in the thermodynamical properties of interacting particle systems are investigated within the framework of the relativistic direct interaction theory in various forms of dynamics. In the front form ...
The canonical u-v Bogolubov transformation in a weakly relativistic statistical theory of a charged particle system

Blazhyjevskii, L.F.; Krynytskyi, Yu.S. (Condensed Matter Physics, 1998)

A weakly relativistic statistical system of charged particles and an electromagnetic field is considered. The effective Hamiltonian of the system is obtained by the canonical Bogolubov transformation. The screening of ...
The role of relativistic kinematics in describing two-quark systems

Lengyel, V.; Rubish, V.; Fekete, Yu.; Chalupka, S.; Salak, M. (Condensed Matter Physics, 1998)

An attempt to incorporate relativistic kinematics in the description of light quark systems is made. It seems that the way of such an incorporation suggested by R.Gaida and his collaborators is very promising. Comparison ...
On the structure of the supplementary series of unitary irreducible representations of the proper, ortochronous Lorentz group

Staruszkiewicz, A. (Condensed Matter Physics, 1998)

Representations from the supplementary series of unitary irreducible representations of the proper, ortochronous Lorentz group are labelled by the parameter z , 0 < z < 1 . There are qualitative differences between ...
Few-particle eigenstates in the Yukawa model

Darewych, J. (Condensed Matter Physics, 1998)

Розглядається переформулювання моделі Юкави, у якій ферміони взаємодіють через посередництво (масивного або безмасового) скалярного поля. За допомогою коваріянтних функцій Ґріна поле, що переносить взаємодію, виражено ...
Thermo field hydrodynamic and kinetic equations of dense quantum nuclear systems

Tokarchuk, M.V.; Arimitsu, T.; Kobryn, A.E. (Condensed Matter Physics, 1998)

Basic equations of nonequilibrium thermo field dynamics of dense quantum systems are presented. A formulation of nonequilibrium thermo field dynamics has been performed using the nonequilibrium statistical operator method ...
The existence and stability of relativistic shock waves: general criteria and numerical simulations for a non-convex equation of state

Tytarenko, P.V.; Zhdanov, V.I. (Condensed Matter Physics, 1998)

A small viscosity approach to discontinuous flows is discussed in relativistic hydrodynamics with a general (possibly, non-convex) equation of state that typically occurs in the domains of phase transitions. Different ...
Supernova remnants as cosmic ray accelerators. SNR IC 443

Hnatyk, B.; Petruk, O. (Condensed Matter Physics, 1998)

We examine the hypothesis that some supernova remnants (SNRs) may be responsible for some unidentified y-ray sources detected by EGRET instrument aboard the Compton Gamma Ray Observatory. If this is the case, y-rays are ...
