Aggressive shadowing of a low-dimensional model of atmospheric dynamics
shadowing, stalking, ensemble forecasting, inflation
2011/9/9
Predictions of the future state of the Earth’s atmosphere suffer from the consequences of chaos: numerical weather forecast models quickly diverge from observations as uncertainty in the initial state...
D1-brane in Constant R-R 3-form Flux and Nambu Dynamics in String Theory
D1-brane Constant R-R 3-form Flux Nambu Dynamics String Theory
2010/12/23
We consider D1-string in a constant R-R 3-form flux background and analyze its low energy limit. The leading order low energy theory has reparametrization symmetry and is a generalization of an earli...
Dynamics and Thermodynamics of (2+1)-Dimensional Evolving Lorentzian Wormhole
Dynamics Thermodynamics of (2+1)-Dimensional Evolving Lorentzian Wormhole
2010/12/27
In this paper we study the relationship between the Einstein field equations for the (2+1)-dimensional evolving wormhole and the first law of thermodynamics. It has been shown that the Einstein field...
Coordinate representation of particle dynamics in AdS and in generic static spacetimes
particle dynamics AdS generic static spacetimes
2010/12/23
We discuss the quantum dynamics of a particle in static curved spacetimes in a coordinate representation. The scheme is based on the analysis of the squared energy operator E^2, which is quadratic in ...
We study dynamics of the classicalization phenomenon suggested in arXiv:1010.1415, according to which a class of non-renormalizable theories self-unitarizes at high-energies via creation of classical...
Fermion localization on branes with generalized dynamics
Fermion localization branes generalized dynamics
2010/12/24
In a recent paper published in this journal, Bazeia and collaborators [Phys. Lett. B 671, (2009) 402] analyze braneworld models with nonstandard dynamics. It was found that the generalized braneworld...
Matrix Model for membrane and dynamics of D-Particles in a curved space-time geometry and presence of form fields
Matrix Model membrane dynamics D-Particles
2010/12/23
We study dynamics of a membrane and its matrix regularisation. We present the matrix regularisation for a membrane propagating in a curved space-time geometry in the presence of an arbitrary 3-form fi...
We consider the construction of Lagrangians that might be suitable for describing the entire $p$-adic sector of an adelic open scalar string. These Lagrangians are constructed using the Lagrangian for...
Chiral Dynamics and Dubna-Mainz-Taipei Dynamical Model for Pion-Photoproduction Reaction
Chiral Dynamics Dubna-Mainz-Taipei Dynamical Model Pion-Photoproduction Reaction
2010/12/29
We demonstrate that the Dubna-Mainz-Taipei (DMT) meson-exchange dynamical model, which starts from an effective chiral Lagrangian, for pion photoproduction provides an excellent and economic framework...
Macroscopic time evolution and MaxEnt inference for closed systems with Hamiltonian dynamics
MaxEnt algorithm information theory statistical mechanics Hamiltonian dynamics
2010/11/24
MaxEnt inference algorithm from the information theory is relevant for the time evolution of macroscopic systems which represents a problem of incomplete information. Two different approaches using Ma...
General Non-equilibrium Theory of Colloid Dynamics
General Non-equilibrium Theory Colloid Dynamics
2010/11/24
A non-equilibrium extension of Onsager’s canonical theory of thermal fluctuations is employed
to derive a self-consistent theory for the description of the statistical properties of the instantaneous...
Anisotropic ultrafast electron dynamics induced by high-field terahertz pulses in n-doped InGaAs
Anisotropic ultrafast electron dynamics high-field terahertz pulses
2010/11/23
The anisotropic effective mass of electrons is directly measured using time-resolved THz-
pump/THz-probe techniques in a n-doped InGaAs semiconductor thin film. A microscopic theory
is used to attri...
We present numerical simulations of a Kerr black hole perturbed by a pulse of ingoing gravitational radiation. For strong perturbations we find up to five concentric marginally outer trapped surfaces....
The dynamics of dark solitons in a trapped superfluid Fermi gas
dynamics of dark solitons trapped superfluid Fermi gas
2010/11/24
We study soliton oscillations in a trapped superfluid Fermi gas across the Bose-Einstein conden-sate to Bardeen-Cooper-Schrieffer (BEC-BCS) crossover. We derive an exact equation relating the phase ju...
Dynamics of Diffeomorphism Degrees of Freedom at a Horizon
Dynamics of Diffeomorphism Degrees Freedom Horizon
2010/12/20
We define a set of boundary conditions that ensure the presence of a null hypersurface with the
essential characteristics of a horizon, using the formalism of weakly isolated horizons as a guide.We t...
