Dynamics of relativistic particle with Lagrangian dependent on acceleration [PDF]
, 1994 Models of relativistic particle with Lagrangian ${\cal L}(k_1)$, depending on the curvature of the worldline $k_1$, are considered. By making use of the Frenet basis, the equations of motion are reformulated in terms of the principal curvatures of the ...

Relativistic particle acceleration in developing Alfv\'{e}n turbulence
, 2009 A new particle acceleration process in a developing Alfv\'{e}n turbulence in the course of successive parametric instabilities of a relativistic pair plasma is investigated by utilyzing one-dimensional electromagnetic full particle code.

Kinematics of a relativistic particle with de Sitter momentum space
, 2010 We discuss kinematical properties of a free relativistic particle with deformed phase space in which momentum space is given by (a submanifold of) de Sitter space.

Quantum Otto engines at relativistic energies
New Journal of Physics, 2021 Relativistic quantum systems exhibit unique features not present at lower energies, such as the existence of both particles and antiparticles, and restrictions placed on the system dynamics due to the light cone.

Flux-Across-Surfaces Theorem for a Dirac Particle
, 2002 We consider the asymptotic evolution of a relativistic spin-1/2-particle. i.e. a particle whose wavefunction satisfies the Dirac equation with external static potential.

Classical relativistic particles [PDF]
Communications in Mathematical Physics, 1971 The concept of Lorentz-invariant classical elementary particle is made precise and it is found that there are exactly two families: (0) the well-known free point-particles distinguished only by their masses and (+) a family with eight-dimensional phase space whose members are distinguished either by their mass or their positive spin.

Relativistic three-particle scattering equations [PDF]
Physical Review C, 1993 We derive a set of relativistic three-particle scattering equations in the three-particle c.m. frame employing a relativistic three-particle propagator suggested long ago by Ahmadzadeh and Tjon in the c.m. frame of a two-particle subsystem. We make the coordinate transformation of this propagator from the c.m. frame of the two-particle subsystem to the

Particle Acceleration and Magnetic Field Amplification by Relativistic Shocks in Inhomogeneous Media
The Astrophysical Journal LettersParticle acceleration and magnetic field amplification in relativistic shocks propagating in inhomogeneous media are investigated by three-dimensional magnetohydrodynamical (MHD) simulations and test-particle simulations.

Dirac Cat States in Relativistic Landau Levels
, 2007 We show that a relativistic version of Schrodinger cat states, here called Dirac cat states, can be built in relativistic Landau levels when an external magnetic field couples to a relativistic spin 1/2 charged particle. Under suitable initial conditions,

Equations of Motion of Spinning Relativistic Particle in External Fields [PDF]
, 1997 We consider the motion of a spinning relativistic particle in external electromagnetic and gravitational fields, to first order in the external field, but to an arbitrary order in spin.
