Lattice Boltzmann method for inhomogeneous fluids
S. Melchionna, U. Marini Bettolo Marconi
We present a lattice-based numerical method to describe the non equilibrium behavior of a simple fluid under non-uniform spatial conditions. The evolution equation for the one-part…
Active one-way quantum computation with 2-photon 4-qubit cluster states
Giuseppe Vallone, Enrico Pomarico, Francesco De Martini +1
By using 2-photon 4-qubit cluster states we demonstrate deterministic one-way quantum computation in single qubit rotation algorithm. In this operation feed-forward measurements ar…
Time Dependent Inelastic Emission and Capture of Localized Electrons in Si n-MOSFETs Under Microwave Irradiation
Enrico Prati, Marco Fanciulli, Alessandro Calderoni +2
Microwave irradiation causes voltage fluctuations in solid state nanodevices. Such an effect is relevant in atomic electronics and nanostructures for quantum information processing…
Quantum state decorrelation
Giacomo M. D'Ariano, Rafal Demkowicz-Dobrzanski, Paolo Perinotti +1
We address the general problem of removing correlations from quantum states while preserving local quantum information as much as possible. We provide a complete solution in the ca…
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…
Nonlinear Dynamics in Double Square Well Potential
Ramaz Khomeriki, Jerome Leon, Stefano Ruffo +1
Considering the coherent nonlinear dynamics in double square well potential we find the example of coexistence of Josephson oscillations with a self-trapping regime. This macroscop…
Long-time tails in sheared fluids
Michio Otsuki, Hisao Hayakawa
The long-time behaviors of the velocity autocorrelation function for sheared fluids ^M are investigated theoretically and numerically. It is found the existence of the cross…
Interaction Ruling Animal Collective Behaviour Depends on Topological rather than Metric Distance: Evidence from a Field Study
M. Ballerini, N. Cabibbo, R. Candelier +9
Numerical models indicate that collective animal behaviour may emerge from simple local rules of interaction among the individuals. However, very little is known about the nature o…
Extracting signatures of quantum criticality in the finite-temperature behavior of many-body systems
Alessandro Cuccoli, Alessio Taiti, Ruggero Vaia +1
We face the problem of detecting and featuring footprints of quantum criticality in the finite-temperature behavior of quantum many-body systems. Our strategy is that of comparing…
Resonance phenomena in asymmetric superconducting quantum interference devices
T. P. Polak, E. Sarnelli
Theory of self induced resonances in asymmetric two-junction interferometer device is presented. In real devices it is impossible to have an ideal interferometer free of imperfecti…
Experimental macroscopic coherence by phase-covariant cloning of a single photon
Eleonora Nagali, Tiziano De Angelis, Fabio Sciarrino +1
We investigate the multiphoton states generated by high-gain optical parametric amplification of a single injected photon, polarization encoded as a ''qubit''. The experiment confi…
Experimental Realization of Polarization Qutrits from Non-Maximally Entangled States
Giuseppe Vallone, Enrico Pomarico, Paolo Mataloni +2
Based on a recent proposal [Phys. Rev. A 71, 062337 (2005)], we have experimentally realized two photon polarization qutrits by using non-maximally entangled states and linear opti…
Intensity correlations, entanglement properties and ghost imaging in multimode thermal-seeded parametric downconversion: Theory
Ivo P. Degiovanni, Maria Bondani, Emiliano Puddu +2
We address parametric-downconversion seeded by multimode pseudo-thermal fields. We show that this process may be used to generate multimode pairwise correlated states with entangle…

Magnetoelectric effects are investigated ab-initio at the interface between half-metallic and ferroelectric prototypes: Heusler CoMnSi and perovskite BaTiO. For the Co-term…

F. Ricci, S. Picozzi, A. Continenza +5
We report a joint theoretical and experimental study focused on understanding the optical and magneto-optical properties of Co-based full-Heusler compounds. We show that magneto-op…
Polaronic features in the optical properties of the Holstein-t-J model
E. Cappelluti, S. Ciuchi, S. Fratini
We derive the exact solution for the optical conductivity of one hole in the Holstein-t-J model in the framework of dynamical mean-field theory (DMFT). We investigate the ma…
