Molecular dynamics simulation of the fragile glass former ortho-terphenyl: a flexible molecule model
S. Mossa, R. Di Leonardo, G. Ruocco +1
We present a realistic model of the fragile glass former orthoterphenyl and the results of extensive molecular dynamics simulations in which we investigated its basic static and dy…
The Raman coupling function in amorphous silica and the nature of the long wavelength excitations in disordered systems
A. Fontana, R. Dell'Anna, M. Montagna +6
New Raman and incoherent neutron scattering data at various temperatures and molecular dynamic simulations in amorphous silica, are compared to obtain the Raman coupling coefficien…
Gamma Ray Bursts via emission of axion-like particles
Zurab Berezhiani, Alessandro Drago
The Pseudo-Goldstone Boson (PGB) emission could provide a very efficient mechanism for explaining the cosmic Gamma Ray Bursts (GRBs). The PGBs could be produced during the merging…
Compact Central WENO Schemes for Multidimensional Conservation Laws
D. Levy, G. Puppo, G. Russo
We present a new third-order central scheme for approximating solutions of systems of conservation laws in one and two space dimensions. In the spirit of Godunov-type schemes,our m…
Acoustic Nature of the Boson Peak in Vitreous Silica
C. Masciovecchio, V. Mazzacurati, G. Monaco +13
New temperature dependent inelastic x-ray (IXS) and Raman (RS) scattering data are compared to each other and with existing inelastic neutron scattering data in vitreous silica (v-…
Phonon-like and single particle dynamics in liquid lithium
T. Scopigno, U. Balucani, A. Cunsolo +4
The dynamic structure factor, S(Q,E), of liquid lithium (T=475 K) has been determined by inelastic x-ray scattering (IXS) in the momentum transfer region (Q = 1.4-110 nm-1). These…
Three and Two Colours Finite Density QCD at Strong Coupling: A New Look
R. Aloisio, V. Azcoiti, G. Di Carlo +2
Simulations in finite density, beta=0 lattice QCD by means of the Monomer-Dimer-Polymer algorithm show a signal of first order transition at finite temporal size. This behaviour ag…
Different Scenarios for Critical Glassy Dynamics
S. Ciuchi, A. Crisanti
We study the role of different terms in the -body potential of glass forming systems on the critical dynamics near the glass transition. Using a simplified spin model with quenc…
A scheme for total quantum teleportation
E. DelRe, B. Crosignani, P. Di Porto
We address the issue of totally teleporting the quantum state of an external particle, as opposed to studies on partial teleportation of external single-particle states, total tele…
Strongly Coupled QCD at Finite Baryon Density
R. Aloisio, V. Azcoiti, G. Di Carlo +2
The analytical results obtained in the infinite mass and strong coupling limits of QCD are difficult to reconcile with the predictions of the Monomer Dimer Polymer algorithm. We ha…
Transaction costs: a new point of view
R. Baviera
We consider a new approach to portfolio selection in presence of transaction costs which allows to map the problem into one without costs. The proposed approach connects all the qu…
Towards a grand unified picture for neutrino and quark mixings
Zurab Berezhiani, Anna Rossi
The comparison of the CKM mixing angles with the leptonic mixings implied by the recent atmospheric and solar neutrino data exhibits an interesting complementarity. This pattern ca…
Entropy Decrease in Isolated Systems with an Internal Wall undergoing Brownian Motion
B. Crosignani, P. Di Porto
We consider an isolated gaseous system, divided in two parts by an adiabatic movable frictionless internal wall undergoing Brownian motion. We show how this kind of motion can lead…
Indeterminacy in foreign exchange market
Michele Pasquini, Maurizio Serva
We discuss price variations distributions in foreign exchange markets, characterizing them both in calendar and business time frameworks. The price dynamics is found to be the resu…
Random dynamical systems, entropies and information
Maurizio Serva
Prediction of events is the challenge in many different disciplines, from meteorology to finance; the more this task is difficult, the more a system is {\it complex}. Nevertheless,…
On the very long term evolutionary behavior of hydrogen-accreting Low-Mass CO white dwarfs
L. Piersanti, S. Cassisi, I. Iben +1
Hydrogen-rich matter has been added to a CO white dwarf of initial mass 0.516 \msun at the rates and \msun \yrm1, and results are compared with those fo…
Non Asymptotic Properties of Transport and Mixing
G. Boffetta, A. Celani, M. Cencini +2
We study relative dispersion of passive scalar in non-ideal cases, i.e. in situations in which asymptotic techniques cannot be applied; typically when the characteristic length sca…
Potential Energy Landscape and Long Time Dynamics in a Simple Model Glass
L. Angelani, G. Parisi, G. Ruocco +1
We analyze the properties of a Lennard-Jones system at the level of the potential energy landscape. After an exhaustive investigation of the topological features of the landscape o…
Clustering of volatility as a multiscale phenomenon
Michele Pasquini, Maurizio Serva
The dynamics of prices in financial markets has been studied intensively both experimentally (data analysis) and theoretically (models). Nevertheless, a complete stochastic charact…
An approximate renormalization-group transformation for Hamiltonian systems with three degrees of freedom
C. Chandre, H. R. Jauslin, G. Benfatto +1
We construct an approximate renormalization transformation that combines Kolmogorov-Arnold-Moser (KAM)and renormalization-group techniques, to analyze instabilities in Hamiltonian…
Finite Density Fat QCD
R. Aloisio, V. Azcoiti, G. Di Carlo +2
Lattice formulation of Finite Baryon Density QCD is problematic from computer simulation point of view; it is well known that for light quark masses the reconstructed partition fun…
Drifters dispersion in the Adriatic Sea: Lagrangian data and chaotic model
Guglielmo Lacorata, Erik Aurell, Angelo Vulpiani
We analyze characteristics of drifter trajectories from the Adriatic Sea with recently introduced nonlinear dynamics techniques. We discuss how in quasi-enclosed basins, relative d…
Efficiency in foreign exchange markets
R. Baviera, M. Pasquini, M. Serva +2
A quantitative check of weak efficiency in US dollar/German mark exchange rates is developed using high frequency data. We show the existence of long term return anomalies. We intr…
