Two-color quantum memory in double Λ-media
D. Viscor, V. Ahufinger, J. Mompart +3
We propose a quantum memory for a single-photon wave packet in a superposition of two different colors, i.e., two different frequency components, using the electromagnetically indu…
Revisiting the Bragg reflector to illustrate some modern developments in optics
S. A. R. Horsley, J. -H. Wu, M. Artoni +1
A series of thin layers of alternating refractive index is known to make a good optical mirror over certain bands of frequency. Such a device - often termed the Bragg reflector - i…
Cross-Phase Modulation and Population Redistribution in a Periodic Tripod Medium
K. Slowik, A. Raczynski, J. Zaremba +3
The cross-Kerr effect is studied for two pulses propagating in an atomic medium in a tripod configuration, dressed by a strong standing wave coupling beam. Nonlinear phase shifts f…
Spinodal of supercooled polarizable water
P. Gallo, M. Minozzi, M. Rovere
We develop a series of molecular dynamics computer simulations of liquid water, performed with a polarizable potential model, to calculate the spinodal line and the curve of maximu…
Is demagnetization an efficient optimization method?
S. Zapperi, F. Colaiori, L. Dante +4
Demagnetization, commonly employed to study ferromagnets, has been proposed as the basis for an optimization tool, a method to find the ground state of a disordered system. Here we…
Fractals vs. halos: Asymptotic scaling without fractal properties
M. Bottaccio, M. Montuori, L. Pietronero
Precise analyses of the statistical and scaling properties of galaxy distribution are essential to elucidate the large-scale structure of the universe. Given the ongoing debate on…
Statistical properties of acoustic emission signals from metal cutting processes
F. A. Farrelly, A. Petri, L. Pitolli +3
Acoustic Emission (AE) data from single point turning machining are analysed in this paper in order to gain a greater insight of the signal statistical properties for Tool Conditio…
Crystal vs glass formation in lattice models with many coexisting ordered phases
Mario J. de Oliveira, Alberto Petri, Tania Tome
We present here new evidence that after a quench the planar Potts model on the square lattice relaxes towards a glassy state if the number of states q is larger than four. By extra…
In-situ acoustic-based analysis system for physical and chemical properties of the lower Martian atmosphere
F. A. Farrelly, A. Petri, L. Pitolli +1
The Environmental Acoustic Reconnaissance and Sounding experiment (EARS), is composed of two parts: the Environmental Acoustic Reconnaissance (EAR) instrument and the Environmental…
Lattice models of disorder with order
Alberto Petri
This paper describes the use of simple lattice models for studying the properties of structurally disordered systems like glasses and granulates. The models considered have crystal…
Glassy states in lattice models with many coexisting crystalline phases
M. J. de Oliveira, A. Petri, T. Tome
We study the emergence of glassy states after a sudden cooling in lattice models with short range interactions and without any a priori quenched disorder. The glassy state emerges…
Poor screening and nonadiabatic superconductivity in correlated systems
L. Boeri, E. Cappelluti, C. Grimaldi +1
In this paper we investigate the role of the electronic correlation on the hole doping dependence of electron-phonon and superconducting properties of cuprates. We introduce a simp…
Electron-phonon renormalization in small Fermi energy systems
E. Cappelluti, L. Pietronero
The puzzling features of recent photoemission data in cuprates have been object of several analysis in order to identity the nature of the underlying electron-boson interaction. In…
Assortative model for social networks
Michele Catanzaro, Guido Caldarelli, Luciano Pietronero
In this paper we present a new version of a network growth model, generalized in order to describe the behavior of social networks. The case of study considered is the preprint arc…
Band-filling effects on electron-phonon properties of normal and superconducting state
E. Cappelluti, S. Ciuchi, C. Grimaldi +1
We address the effect of band filling on the effective electron mass and the superconducting critical temperature in a electron-phonon system. We compare the vertex cor…
Formation and mobility of oxygen vacancies in RuSr2GdCu2O8
F. Cordero, M. Ferretti, M. R. Cimberle +1
Oxygen vacancies are introduced in the RuO2 and possibly CuO2 planes of RuSr2GdCu2O8 by annealing in vacuum above 600 K. The diffusive jumps of the O vacancies are accompanied by a…
Critical fluctuations in the breakdown of disordered systems
Alberto Petri
In this paper some critical aspects of the behaviour of breaking lattices subject to slow driving forces are briefly reviewed. In particular fluctuations in the response to the var…
Dynamic Fracture Model for Acoustic Emission
Manuela Minozzi, Guido Caldarelli, Luciano Pietronero +1
We study the acoustic emission produced by micro-cracks using a two-dimensional disordered lattice model of dynamic fracture, which allows to relate the acoustic response to the in…
A microscopic 2D lattice model of dimer granular compaction with friction
C. Fusco, A. Fasolino, P. Gallo +2
We study by Monte Carlo simulation the compaction dynamics of hard dimers in 2D under the action of gravity, subjected to vertical and horizontal shaking, considering also the case…
Anelastic relaxation process of polaronic origin in La{2-x}Sr{x}CuO{4}: interaction between the charge stripes and pinning centers
F. Cordero, A. Paolone, R. Cantelli +1
The evolution of an anelastic relaxation process occurring around 80 K in La{2-x}Sr{x}CuO{4} at a measuring frequency of ~1 kHz has been followed from x = 0.0075 to the overdoped r…
