Scalar charged particle in Weyl--Wigner--Moyal phase space. Constant magnetic field
B. I. Lev, A. A. Semenov, C. V. Usenko
A relativistic phase-space representation for a class of observables with matrix-valued Weyl symbols proportional to the identity matrix (charge-invariant observables)is proposed.…
Squeezed states and quantum chaos
Kirill N. Alekseev, Dima S. Primak
We examine the dynamics of a wave packet that initially corresponds to a coherent state in the model of quantum kicked rotator. This main model of quantum chaos, which allows for a…
Motion of vortex lines in nonlinear wave mechanics
Iwo Bialynicki-Birula, Zofia Bialynicka-Birula
We extend our previous analysis of the motion of vortex lines [I. Bialynicki-Birula, Z. Bialynicka-Birula and C. Sliwa, Phys. Rev. A 61, 032110 (2000)] from linear to a nonlinear S…
Spatial evolution of short pulses under coherent population trapping
V. G. Arkhipkin, I. V. Timofeev
Spatial and temporal evolution is studied of two powerful short laser pulses having different wavelengths and interacting with a dense three-level Lambda-type optical medium under…
Peculiarities of the Weyl - Wigner - Moyal formalism for scalar charged particles
B. I. Lev, A. A. Semenov, C. V. Usenko
A description of scalar charged particles, based on the Feshbach-Villars formalism, is proposed. Particles are described by an object that is a Wigner function in usual coordinates…
