Magneto-optical properties of (Ga,Mn)As: an ab--initio determination
A. Stroppa, S. Picozzi, A. Continenza +2
The magneto-optical properties of (Ga,Mn)As have been determined within density functional theory using the highly precise full-potential linear augmented plane wave (FLAPW) method…
Phase transitions of bipartite entanglement
P. Facchi, U. Marzolino, G. Parisi +2
We study a random matrix model for the statistical properties of the purity of a bipartite quantum system at a finite (fictitious) temperature. This enables us to write the generat…
Fluctuation-Response Relation and modeling in systems with fast and slow dynamics
Guglielmo Lacorata, Angelo Vulpiani
We show how a general formulation of the Fluctuation-Response Relation is able to describe in detail the connection between response properties to external perturbations and sponta…
Conservation laws with vanishing nonlinear diffusion and dispersion
Philippe G. LeFloch, Roberto Natalini
We study the limiting behavior of the solutions to a class of conservation laws with vanishing nonlinear diffusion and dispersion terms. We prove the convergence to the entropy sol…
Theory of semiconductor quantum-wire based single- and two-qubit gates
Tobias Zibold, Peter Vogl, Andrea Bertoni
A GaAs/AlGaAs based two-qubit quantum device that allows the controlled generation and straightforward detection of entanglement by measuring a stationary current-voltage character…
Reply to Comment on ``Spherical 2+p spin-glass model: an analytically solvable model with a glass-to-glass transition''
A. Crisanti, L. Leuzzi
In his Comment, Krakoviack [Phys. Rev. B (2007)] finds that the phase behavior of the s+p spin-glass model is different from what proposed by Crisanti and Leuzzi [Phys. Rev. B 73,…
