A geometrical approach to non-adiabatic transitions in quantum theory: applications to NMR, over-barrier reflection and parametric excitation of quantum oscillator
M. S. Marinov, E. Strahov
This article deals with non-adiabatic processes (i.e. processes excluded by the adiabatic theorem) from the geometrical (group-theoretical) point of view. An approximated formula f…
Spin in a variable magnetic field: the adiabatic approximation
M. S. Marinov, Eugene Strahov
The problem of spin precession in a time-dependent magnetic field is considered in the adiabatic approximation where the field direction or the angular velocity of its rotation is…
Exact Evolution Operator on Non-compact Group Manifolds
Nurit Krausz, M. S. Marinov
Free quantal motion on group manifolds is considered. The Hamiltonian is given by the Laplace -- Beltrami operator on the group manifold, and the purpose is to get the (Feynman's)…
On the concept of the tunneling time
M. S. Marinov, Bilha Segev
Asymptotic time evolution of a wave packet describing a non-relativistic particle incident on a potential barrier is considered, using the Wigner phase-space distribution. The dist…
Quantum Tunneling in the Wigner Representation
M. S. Marinov, Bilha Segev
Time dependence for barrier penetration is considered in the phase space. An asymptotic phase-space propagator for nonrelativistic scattering on a one - dimensional barrier is cons…
Analytical properties of scattering amplitudes in one-dimensional quantum theory
M. S. Marinov, Bilha Segev
One-dimensional quantum scattering from a local potential barrier is considered. Analytical properties of the scattering amplitudes have been investigated by means of the integral…
