Microscopic theory of vibronic dynamics in linear polyenes
L. Arrachea, A. A. Aligia, G. E. Santoro
We propose a novel approach to calculate dynamical processes at ultrafast time scale in molecules in which vibrational and electronic motions are strongly mixed. The relevant elect…

The infinite-range quantum random Heisenberg magnet
L. Arrachea, M. J. Rozenberg
We study with exact diagonalization techniques the Heisenberg model for a system of SU(2) spins with S=1/2 and random infinite-range exchange interactions. We calculate the critica…

Current oscillations in a metallic ring threaded by a time-dependent magnetic flux
L. Arrachea
We study a mesoscopic metallic ring threaded by a magnetic flux which varies linearly in time PhiM(t)=Phi t with a formalism based in Baym-Kadanoff-Keldysh non-equilibrium Green fu…
