A method for solving gyroscopic equations with operators
Claude Aslangul
The dynamics of a set of identical spins interacting with another one through a time-dependent coupling gives rise to a gyroscopic equation with a variable Larmor frequency and, mo…
Surprises in the suddenly-expanded infinite well
Claude Aslangul
I study the time-evolution of a particle prepared in the ground state of an infinite well after the latter is suddenly expanded. It turns out that the probability density $|Ψ(x, t)…
Quantum Dynamics of a Particle with a Spin-dependent Velocity
Claude Aslangul
We study the dynamics of a particle in continuous time and space, the displacement of which is governed by an internal degree of freedom (spin). In one definite limit, the so-calle…
Effect of a forbidden site on a d-dimensional lattice random walk
Nicolas Martzel, Claude Aslangul
We study the effect of a single excluded site on the diffusion of a particle undergoing random walk in a d-dimensional lattice. The determination of the characteristic function all…
Diffusion of two repulsive particles in a one-dimensional lattice
Claude Aslangul
The problem of the lattice diffusion of two particles coupled by a contact repulsive interaction is solved by finding analytical expressions of the two-body probability characteris…
Single-file Diffusion with Random Diffusion Constants
Claude Aslangul
The single-file problem of N particles in one spatial dimension is analyzed, when each particle has a randomly distributed diffusion constant D sampled in a density . The ave…
