Abstract We studied the dynamics of surfacea and wake charges induced by a charged particle traversing a dielectric slab. It is shown that after the crossing of the slab first boundary, the induced on the slab surface charge (image charge) is transformed into the wake charge, which overflows to the second boundary when the particle crosses it. It is also shown, that the polarization of the slab...

132 LLE Review, Volume 67 The motion of a charged particle in an electromagnetic field is a well-known paradigm of physics.1,2 Suppose that the field is associated with a laser pulse of finite extent propagating in a vacuum. As the pulse overtakes the particle, the particle gains energy and momentum at the expense of the pulse. At the peak of an intense pulse, the particle has considerable (lon...

We analyse the long-time tails of a charged quantum Brownian particle in harmonic potential presence magnetic field using Quantum Langevin Equation as starting point. position-autocorrelation function, position–velocity correlation function and velocity-autocorrelation function. study these correlations for coupled to Ohmic Drude baths, via position coordinate coupling. At finite temperatures w...

We reconstruct a 3+1 formalism of general relativistic electromagnetism, and derive the equations of motion of charged particles in the pulsar magnetosphere, taking account of the inclination between the rotation axis and the magnetic axis. Apart from the previous works where space charge is evaluated by assuming the flow velocity being the light speed, we analyze particle motion in the polar c...

We discover a fundamental mechanism for the sharp increase in the diffusion rate of the motion of a charged particle in a uniform magnetic field when a time-periodic electricfield propagating orthogonally to the magnetic field is slightly tilted. It is associated with the degeneracies of the underlying motion; in fact, a two-degree of freedom mechanism of instability induces this behaviour. Unf...
