Time evolution of the classical and quantum mechanical versions of diffusive anharmonic oscillator: an example of Lie algebraic techniques

J. G. Peixoto de Faria

We present the general solutions for the classical and quantum dynamics of the anharmonic oscillator coupled to a purely diffusive environment. In both cases, these solutions are o…

Classical and quantum coupled oscillators: symplectic structure

A. R. Bosco de Magalhães, C. H. d'Ávila Fonseca, M. C. Nemes

We consider a set of N linearly coupled harmonic oscillators and show that the diagonalization of this problem can be put in geometrical terms. The matrix techniques developed here…

Spin Dynamics in the Two-Dimensional Spin 1/2 Heisenberg Antiferromagnet

A. F. Albuquerque, A. S. T. Pires, M. E. Gouvea

We present low-temperature dynamic properties of the quantum two-dimensional antiferromagnetic Heisenberg model with spin S=1/2. The calculation of the dynamic correlation function…
