Role of initial conditions in the dynamics of quantum glassy systems
(IOP Publishing, 2019-02-25)
We set the formalism to study the way in which the choice of canonical equilibrium initial conditions affect the real-time dynamics of quantum disordered models. We use a path integral formulation on a time contour with ...
A NEW APPROACH TO THE ELECTRONIC-STRUCTURE OF 2-DIMENSIONAL DISORDERED ALLOYS
(Pergamon-elsevier Science LtdOxfordInglaterra, 1995)
Anderson localization and momentum-space entanglement
(Iop Publishing Ltd, 2014-07-01)
We consider Anderson localization and the associated metal-insulator transition for non-interacting fermions in D = 1, 2 space dimensions in the presence of spatially correlated on-site random potentials. To assess the ...
Quantum state transfer in disordered spin chains: How much engineering is reasonable?
(Rinton Press, Inc, 2015-05-01)
The transmission of quantum states through spin chains is an important element in the implementation of quantum information technologies. Speed and fidelity of transfer are the main objectives which have to be achieved by ...
Phase transitions and order-by-quantum disorder for the anti- ferromagnetic XY model in the checkerboard lattice
(Journal of Magnetism and Magnetic Materials, 2018)
Disordered Bose-Einstein condensate in hard walls trap
(Iop Publishing Ltd, 2019-11-01)
We discuss the effects of quenched disorder in a dilute Bose-Einstein condensate confined in a hard walls trap. Starting from the disordered Gross-Pitaevskii functional, we obtain a representation for the quenched free ...
A new approach to the electronic structure of two dimensional disordered alloys
(Elsevier B.V., 1995-06-01)
We propose a novel method to calculate the electronic Density of States (DOS) of a two dimensional disordered binary alloy. The method is highly reliable and numerically efficient, and Short Range Order (SRO) correlations ...
