Quantum states of electromagnetic field interacting with a classical current and their applications to radiation problems
V. G. Bagrov, D. M. Gitman, A. A. Shishmarev +1
In the beginning, the synchrotron radiation (SR) was studied by classical methods using the Liénard-Wiechert potentials of electric currents. Subsequently, quantum corrections to t…
Quantization of charged fields in the presence of critical potential steps
S. P. Gavrilov, D. M. Gitman
QFT approaches elaborated for treating quantum effects in time-dependent external electric fields are not directly applicable to time-independent nonuniform electric fields that ar…
Coherent and semiclassical states of a free particle
V. G. Bagrov, D. M. Gitman, A. S. Pereira
Coherent states (CS) were first introduced and studied in detail for bound motion and discrete-spectrum systems like harmonic oscillators and similar systems with a quadratic Hamil…
Coherent states of systems with quadratic Hamiltonians
V. G. Bagrov, D. M. Gitman, A. S. Pereira
Different families of generalized CS for one-dimensional systems with general time dependent quadratic Hamiltonian are constructed. In principle, all known CS of systems with quadr…
Photon propagation in noncommutative QED with constant external field
R. Fresneda, D. M. Gitman, A. E. Shabad
We find dispersion laws for the photon propagating in the presence of mutually orthogonal constant external electric and magnetic fields in the context of the -expanded noncommu…
Statistical properties of states in QED with unstable vacuum
S. P. Gavrilov, D. M. Gitman, A. A. Shishmarev
We study statistical properties of states of massive quantized charged Dirac and Klein-Gordon fields interacting with a background that violates the vacuum stability, first in gene…
