Semiclassical catastrophes and accumulative angular squeezing of a kicked quantum rotor
M. Leibscher, I. Sh. Averbukh, P. Rozmej +1
We present a detailed theory of spectacular semiclassical catastrophes happening during the time evolution of a kicked quantum rotor (Phys.Rev. Lett. {\bf 87}, 163601 (2001)). Both…
Controlling Quantum Rotation With Light
I. Sh. Averbukh, R. Arvieu, M. Leibscher
Semiclassical catastrophes in the dynamics of a quantum rotor (molecule) driven by a strong time-varying field are considered. We show that for strong enough fields, a sharp peak i…
Relativistic precession and spin dynamics of an elliptic Rydberg wave packet
P. Rozmej, M. Turek, R. Arvieu +1
Time evolution of wave packets built from the eigenstates of the Dirac equation for a hydrogenic system is considered. We investigate the space and spin motion of wave packets whic…
Spin-orbit pendulum - Relativistic extension
M. Turek, P. Rozmej, R. Arvieu
We discuss an extension of the theory of {\em spin-orbit pendulum} phenomenon given in [1] to relativistic approach. It is done within the so called Dirac Oscillator. Our first res…
The Dirac Oscillator. A relativistic version of the Jaynes--Cummings model
P. Rozmej, R. Arvieu
The dynamics of wave packets in a relativistic Dirac oscillator is compared to that of the Jaynes-Cummings model. The strong spin-orbit coupling of the Dirac oscillator produces th…
Geometrical properties of intelligent spin states and time evolution of coherent states
R. Arvieu, P. Rozmej
We remind the properties of the intelligent (and quasi-intelligent) spin states introduced by Aragone et al. We use these states to construct families of coherent wave packets on t…
