ANIMATIONS

We present here some of the animations of the temporal evolution of the One-Dimensional Gaussian Wave Packet (1DGWP) with different configurations of the initial pseudospinor.

CODENAME: 500.0_200.0_0.14_20.0_0.0_0.0_0.0_0J

Temporal Evolution of the Probability Density of a 1DGWP, showing the sum of the square of the pseudospinor components (purple), the A component (red) and the B component (blue).


The initial pseudospinor component is:

A = 1

B = 0

The length of the infinite quantum well is 500 Angstroms.


It evolves through 200 steps in time (around 50 femtoseconds).


Initial wave number = 0.14 Angstroms^(-1).

Initial WP dispersion sigma = 20 Angstroms.

The height of the potential barrier is equal to zero.

The lineal parameter of Rashba Spin-Orbit Interaction alfa = 0.

The cubic parameter of Rashba Spin-Orbit Interaction beta = 0.
