Magnetically induced electronic ferroelectricity in half-doped manganites
Gianluca Giovannetti, Sanjeev Kumar, Jeroen van den Brink +1
Using a joint approach of density functional theory and model calculations, we demonstrate that a prototypical charge ordered half-doped manganite, LaCaMnO is m…
Approximate factor analysis model building via alternating I-divergence minimization
Lorenzo Finesso, Peter Spreij
Given a positive definite covariance matrix , we strive to construct an optimal \emph{approximate} factor analysis model , with having a prescribed numb…
Prompt TeV Emission from Cosmic Rays Accelerated by Gamma Ray Bursts Interacting with Surrounding Stellar Wind
Soebur Razzaque, Olga Mena, Charles D. Dermer
Protons accelerated in the internal shocks of a long duration gamma ray burst can escape the fireball as cosmic rays by converting to neutrons. Hadronic interactions of these neutr…
Selection rules for Single-Chain-Magnet behavior in non-collinear Ising systems
Alessandro Vindigni, Maria Gloria Pini
The magnetic behavior of molecular Single-Chain Magnets is investigated in the framework of a one-dimensional Ising model with single spin-flip Glauber dynamics. Opportune modifica…
Ising spin glass transition in magnetic field out of mean-field
L Leuzzi, G. Parisi, F. Ricci-Tersenghi +1
The spin-glass transition in external magnetic field is studied both in and out of the limit of validity of mean-field theory on a diluted one dimensional chain of Ising spins wher…
Time-evolving measures and macroscopic modeling of pedestrian flow
Benedetto Piccoli, Andrea Tosin
This paper deals with the early results of a new model of pedestrian flow, conceived within a measure-theoretical framework. The modeling approach consists in a discrete-time Euler…
