Oscillations arising when switching on/off a discontinuous magnetic field
Petro Romanets
In the present paper, we theoretically study the effect of density of state variation on the phenomena in the discontinuous magnetic field. Special attention is paid to the transie…
Non-linear additives to the Brooks-Herring screened potential
P. N. Romanets
In the present work we calculate the non-linear additives to the Brooks-Herring electrostatic screened potential. We also calculate the corresponding additives to the ionized impur…
Electron gas under the discontinuous magnetic field of cylindrical symmetry
P. N. Romanets
We study the states of 3D-electron gas in non-homogeneous magnetic field. It is supposed that the step of magnetic field, at which field changes its sign, lies on the cylindrical s…
Depletion of carriers and negative differential conductivity in an intrinsic graphene under a dc electric field
P. N. Romanets, F. T. Vasko
The heating of carriers in an intrinsic graphene under an abrupt switching off a dc electric field is examined taking into account both the energy relaxation via acoustic and optic…
Rabi oscillations under ultrafast excitation of graphene
P. N. Romanets, F. T. Vasko
We study coherent nonlinear dynamics of carriers under ultrafast interband excitation of an intrinsic graphene. The Rabi oscillations of response appear with increasing of pumping…
Transient response under ultrafast interband excitation of an intrinsic graphene
P. N. Romanets, F. T. Vasko
The transient evolution of carriers in an intrinsic graphene under ultrafast excitation, which is caused by the collisionless interband transitions, is studied theoretically. The e…
