- ItemQUANTUM-WELL COMPOUNDS(1992) CLARO, F; MEDINA, RWe show that forming linear sequences of quantum wells of two different types allows for a rich new variety in energy spectra and density of states for nanostructures. In the case of a one-dimensional periodic array such as a string of dots of two kinds, the phase diagram exhibits a new kind of criticality, in the sense that there are conducting phases arbitrarily close in concentration to any insulating phase, and vice versa.
- ItemTHE ITZYKSON-ZUBER INTEGRAL FOR U(M/N)(1995) ALFARO, J; MEDINA, R; URRUTIA, LF
- ItemTHE ORTHOGONALITY RELATIONS FOR THE SUPERGROUP U(M-VERTICAL-BAR-N)(1995) ALFARO, J; MEDINA, R; URRUTIA, LFStarting from the generalization of the Itzykson-Zuber integral for U(m/n) we study the orthogonality relations for this supergroup.
