Spin Densities in Pseudo - Classical Kinetic Theory
It is shown that classical many-particle systems based on N=1 supersymmetry allow for observable consequences of the spin degrees of freedom. In contrast to the one-particle system, where a consistent formulation of spinspace density is impossible, the many-particle system allows for spin to enter into the equations of motion in a non-trivial way. This density can then be directly compared to t...
متن کاملPseudoclassical Mechanics for the Spin 0 and 1 Particles
We give an action for the massless spinning particle in pseudoclassical mechanics by using grassmann variables. The constructed action is invariant under τ-reparametrizations, local SUSY and O(N) transformations. After quantization, for the special case N = 2, we get an action which describes the spin 0, 1 particles and topological sectors of the massless DKP theory. A SUSY formulation of the g...
متن کاملPseudoclassical theory for fidelity of nearly resonant quantum rotors.
Using a semiclassical ansatz we analytically predict for the fidelity of delta-kicked rotors the occurrence of revivals and the disappearance of intermediate revival peaks arising from the breaking of a symmetry in the initial conditions. A numerical verification of the predicted effects is given and experimental ramifications are discussed.

متن کاملSpin susceptibilities, spin densities, and their connection to spin currents
We calculate the frequency-dependent spin susceptibilities for a two-dimensional electron gas with both Rashba and Dresselhaus spin-orbit interactions. The resonances of the susceptibilities depend on the relative values of the Rashba and Dresselhaus spin-orbit constants, which could be manipulated by gate voltages. We derive exact continuity equations, with source terms, for the spin density a...
