Three-site quantum lattice with thermal bath
An algorithm to simulate the dynamics of a quantum state over a three-site lattice interacting with classical harmonic oscillators has been devised. The oscillators are linearly coupled to the quantum state and are acted upon by a fluctuation-dissipation process to take the equilibrium thermal environment into account, thus allowing to investigate how stochastic forces may affect the quantum dynamics. The implementation of the algorithm has been written in Ada95.
