Dynamics of cosmological models with nonlinear classical phantom scalar fields. II. Qualitative analysis and numerical modeling

open access: yes, 2019
A detailed qualitative analysis and numerical modeling of the evolution of cosmological models based on nonlinear classical and phantom scalar fields with self-action are performed.

Classical stochastic measurement trajectories: Bosonic atomic gases in an optical cavity and quantum measurement backaction

open access: yes, 2014
We formulate computationally efficient classical stochastic measurement trajectories for a multimode quantum system under continuous observation. Specifically, we consider the nonlinear dynamics of an atomic Bose-Einstein condensate contained within an ...

Two-phase framework for optimal multi-target Lambert rendezvous

open access: yes, 2017
This paper proposes a two-phase framework to solve an optimal multi-target Lambert rendezvous problem. The first phase solves a series of single-target rendezvous problems for all departure-arrival object pairs to generate the elementary solutions, which

Synchronization along quantum trajectories

open access: yes, 2020
We employ a quantum trajectory approach to characterize synchronization and phase-locking between open quantum systems in nonequilibrium steady states. We exemplify our proposal for the paradigmatic case of two quantum Van der Pol oscillators interacting

Stability of trajectories for N -particles dynamics with singular potential [PDF]

open access: yes, 2010
We study the stability in finite times of the trajectories of interacting particles. Our aim is to show that in average and uniformly in the number of particles, two trajectories whose initial positions in phase space are close, remain close enough at ...

An optimal control approach of integrating traffic signals and cooperative vehicle trajectories at intersections

open access: yesTransportmetrica B: Transport Dynamics, 2021
An integrated approach for optimising traffic signals and cooperative vehicle trajectories at urban intersections is proposed. The upper layer determines the optimal signals using enumeration and the lower layer optimises trajectories under each feasible

Generalized isocline method of plotting phase-plane trajectories [PDF]

open access: yesIEEE Transactions on Automatic Control, 1965
By considering simultaneously the N-x (or the N-\dot{x} ), where N=d\dot{x}/dx and the \dot{x}-x planes, second order non-linear autonomous systems (not easily amendable to the existing methods) described by the differential equation \ddot{x}=F(x, \dot{x}) can be studied.

Selkov’s Dynamic System of Fractional Variable Order with Non-Constant Coefficients

open access: yesMathematics
This article uses an approach based on the triad model–algorithm–program. The model is a nonlinear dynamic Selkov system with non-constant coefficients and fractional derivatives of the Gerasimov–Caputo type.

Geometric Phase and Non-Adiabatic Effects in an Electronic Harmonic Oscillator

open access: yes, 2011
Steering a quantum harmonic oscillator state along cyclic trajectories leads to a path-dependent geometric phase. Here we describe an experiment observing this geometric phase in an electronic harmonic oscillator.

Caustic design in periodic lattices [PDF]

open access: yes, 2012
We study curved trajectory dynamics and design in discrete array settings. We find that beams with power law phases produce curved caustics associated with the fold and cusp type catastrophes.
