Energy landscapes, ideal glasses, and their equation of state
M. S. Shell, P. G. Debenedetti, E. La Nave +1
Using the inherent structure formalism originally proposed by Stillinger and Weber [Phys. Rev. A 25, 978 (1982)], we generalize the thermodynamics of an energy landscape that has a…
On the relationship between directed percolation and the synchronization transition in spatially extended systems
F. Ginelli, R. Livi, A. Politi +1
We study the nature of the synchronization transition in spatially extended systems by discussing a simple stochastic model. An analytic argument is put forward showing that, in th…
Degree stability of a minimum spanning tree of price return and volatility
Salvatore Miccichè, Giovanni Bonanno, Fabrizio Lillo +1
We investigate the time series of the degree of minimum spanning trees obtained by using a correlation based clustering procedure which is starting from (i) asset return and (ii) v…
Quantum resonances and decoherence for delta-kicked atoms
Sandro Wimberger, Italo Guarneri, Shmuel Fishman
The quantum resonances occurring with delta-kicked atoms when the kicking period is an integer multiple of the half-Talbot time are analyzed in detail. Exact results about the mome…
Real-Time Wavelet-transform spectrum analyzer for the investigation of 1/f^αnoise
Doriano Brogioli, Alberto Vailati
A wavelet transform spectrum analyzer operating in real time within the frequency range 3X10^(-5) - 1.3X10^5 Hz has been implemented on a low-cost Digital Signal Processing board o…
Structure, rotational dynamics, and superfluidity of small OCS-doped He clusters
Saverio Moroni, Antonio Sarsa, Stefano Fantoni +2
The structural and dynamical properties of OCS molecules solvated in Helium clusters are studied using reptation quantum Monte Carlo, for cluster sizes n=3-20 He atoms. Computer si…
Near-field light emission from nano- and micrometric complex structures
M. Pieruccini, S. Savasta, R. Girlanda +2
We propose a general theoretical scheme for the investigation of light emitted from nano- and micrometric structures of arbitrary shape and composition. More specifically, the prop…
Anharmonic Self-Energy of Phonons: Ab Initio Calculations and Neutron Spin Echo Measurements
A. Debernardi, F. de Geuser, J. Kulda +2
We have calculated (ab initio) and measured (by spin-echo techniques) the anharmonic self-energy of phonons at the X-point of the Brillouin zone for isotopically pure germanium. Th…
Computer simulation of structural properties of dilute aqueous solutions of argon at supercritical conditions
V. De Grandis, P. Gallo, M. Rovere
Computer simulation studies of aqueous solutions of argon are performed from ambient to supercritical conditions by using a recent polarizable potential model (BSV) and the non pol…
On-Site Repulsion as the Source of Pairing in Carbon Nanotubes and Intercalated Graphite
Enrico Perfetto, Gianluca Stefanucci, Michele Cini
We show that different non-conventional superconductors have one fundamental feature in common: pair eigenstates of the Hamiltonian are repulsion-free, the W=0 pairs. In extended H…
Evidences of vortex curvature and anisotropic pinning in superconducting films by quantitative magneto-optics
F. Laviano, D. Botta, A. Chiodoni +5
We present the experimental observation of magnetic field line curvature at the surface of a superconducting film by local quantitative magneto-optics. In addition to the knowledge…
Spontaneous magnetization of the Ising model on the Sierpinski carpet fractal, a rigorous result
A. Vezzani
We give a rigorous proof of the existence of spontaneous magnetization at finite temperature for the Ising spin model defined on the Sierpinski carpet fractal. The theorem is inspi…
A simplified numerical model of coronal energy dissipation based on reduced MHD
E. Buchlin, V. Aletti, S. Galtier +3
A 3D model intermediate between cellular automata (CA) models and the reduced magnetohydrodynamic (RMHD) equations is presented to simulate solar impulsive events generated along a…
Harmonic generation by atoms in circularly polarized two-color laser fields with coplanar polarizations and commensurate frequencies
F. Ceccherini, D. Bauer, F. Cornolti
The generation of harmonics by atoms or ions in a two-color, coplanar field configuration with commensurate frequencies is investigated through both, an analytical calculation base…
Comment on "Aging, phase ordering and conformal invariance"
Federico Corberi, Eugenio Lippiello, Marco Zannetti
This is a Comment on the Article ``Aging, phase ordering and conformal invariance'' by M.Henkel, M.Pleimling, C.Godrèche and J.M.Luck [Phys.Rev.Lett. 87, 265701 (2001)].
Linear response function around a localized impurity in a superconductor
G. G. N. Angilella, F. E. Leys, N. H. March +1
Imaging the effects of an impurity like Zn in high-Tc superconductors [Nature 61 (2000) 746] has rekindled interest in defect problems in the superconducting phase. This has prompt…
Phase transitions in simple and not so simple binary fluids
A. Parola, D. Pini, L. Reatto +1
Compared to pure fluids, binary mixtures display a very diverse phase behavior, which depends sensitively on the parameters of the microscopic potential. Here we investigate the ph…
Phase diagram of symmetric binary mixtures at equimolar and non-equimolar concentrations: a systematic investigation
D. Pini, M. Tau, A. Parola +1
We consider symmetric binary mixtures consisting of spherical particles with equal diameters interacting via a hard-core plus attractive tail potential with strengths epsilon_{ij},…
All-optical single-electron read-out devices based on GaN quantum dots
Irene D'Amico, Fausto Rossi
We study few-particle interactions in GaN-coupled quantum dots and discuss how the built-in field characteristic of these structures strongly reinforce dipole-dipole and dipole-mon…
Imprinting a complete information about a quantum channel on its output state
Giacomo Mauro D'Ariano, Paoloplacido Lo Presti
We introduce a novel property of bipartite quantum states, which we call "faithfulness", and we say that a state is faithful when acting with a channel on one of the two quantum sy…

Matteo G. A. Paris, Mary Cola, Rodolfo Bonifacio
We suggest a general scheme for quantum state engineering based on conditional measurements carried out on entangled twin-beam of radiation. Realistic detection schemes such as {\s…
