Dissipative quantum systems modeled by a two level reservoir coupling
A. O. Caldeira, A. H. Castro Neto, T. Oliveira de Carvalho
The coupling between a quantum dynamical system and a two-level system reservoir is analysed within the framework of the Feynman-Vernon theory. We stress the differences between th…

On Quantum Scattering of a System with Internal Degrees of Freedom
A. H. Castro Neto, A. O. Caldeira
We study the quantum tunnelling of a very complex object of which only part is coupled to an external potential ( the potential barrier ). We treat this problem as the tunnelling o…

Dynamical decoupling and Kac-Moody current representation in multicomponent integrable systems
J. M. P. Carmelo, A. H. Castro Neto
The conformal invariant character of -multicomponent integrable systems (with branches of gapless excitations) is described from the point of view of the response to curvatu…
