Dynamics of relativistic particle with Lagrangian dependent on acceleration
V. V. Nesterenko, A. Feoli, G. Scarpetta
Models of relativistic particle with Lagrangian , depending on the curvature of the worldline , are considered. By making use of the Frenet basis, the equations…
A Class of Quantum States with Classical-like Evolution
S. De Martino, S. De Siena, F. Illuminati
In the framework of Nelson stochastic quantization we derive exact non-stationary states for a class of time-dependent potentials. The wave-packets follow a classical motion with c…
Diffusion Processes and Coherent States
S. De Martino, S. De Siena, F. Illuminati +1
It is shown that stochastic processes of diffusion type possess, in all generality, a structure of uncertainty relations and of coherent and squeezed states. This fact is used to o…
Nonlinear dynamics in one and two dimensional arrays of discrete Josephson elements
R. D. Parmentier
Discrete arrays of Josephson junction elements differ from their continuum counterparts in two essential ways: i) localized dynamic states in discrete arrays, which are not present…
Scaling and Crossover in the Large-N Model for Growth Kinetics
Antonio Coniglio, Patrizia Ruggiero, Marco Zannetti
The dependence of the scaling properties of the structure factor on space dimensionality, range of interaction, initial and final conditions, presence or absence of a conservation…
Moduli of vector bundles on projective surfaces: some basic results
Kieran G. O'Grady
We prove that moduli spaces of torsion-free sheaves on a projective smooth complex surface are irreducible, reduced and of the expected dimension, provided the expected dimension i…
