Quantum Trajectory in Multi-Dimensional Non-Linear System
نویسنده
چکیده
We discuss quantum dynamics in multi-dimensional non-linear systems. It is well-known that wave function is localized in a single kicked rotor. However, coupling with other degrees of freedom breaks the localization. In order to clarify the difference in the quantum dynamics, we use rigid quantum trajectories, which is accompanied with the de BroglieBohm interpretation of the quantum mechanics. The bundle of quantum trajectories are repulsive by the quantum potential and flow never to go across each other. We shows that, depending on the degrees of freedom, this same property appears differently. keywords: quantum chaos, localization, quantum trajectory, de BroglieBohm interpretation Electronic address:[email protected]

When the classical & quantum mechanical considerations hint to a single point; a microscopic particle in a one dimensional box with two infinite walls and a linear potential inside it
In this paper we have solved analytically the Schrödinger equation for a microscopic particle in a one-dimensional box with two infinite walls, which the potential function inside it, has a linear form. Based on the solutions of this special quantum mechanical system, we have shown that as the quantum number approaches infinity the expectation values of microscopic particle position and square ...
متن کاملTrajectory Tracking Weeled Mobile Robot Using Backstepping Method with Connection off Axle Trailer
The connection of the tractor to the inactive trailer or motor vehicle causes a motion control problem when turning in the screw, forward or backward movements and high speeds. This is due to the inactive trailer being controlled by the tracking using a physical link that is not affected by the movement. Trailers usually take tracks under these conditions. This phenomenon is called Jack Knife. ...
متن کاملTrajectory tracking for quantum systems: a Lyapounov approach
A Lyapounov-based approach for trajectory tracking of the Schrödinger equation is proposed. In the finite dimensional case, convergence is analyzed: the connection between the controllability of the linear tangent approximation around the reference trajectory and asymptotic tracking is studied. Closed-loop simulations of a physical example illustrate the interest of such feedback laws for large...

Based on learning control methods and computational intelligence, control of quantum systems is an attractive field of study in control engineering. What is important is to establish control approach ensuring that the control process converges to achieve a given control objective and at the same time it is simple and clear. In this paper, a learning control method based on genetic quantum contr...
متن کاملDesign of an Intelligent Controller for Station Keeping, Attitude Control, and Path Tracking of a Quadrotor Using Recursive Neural Networks
During recent years there has been growing interest in unmanned aerial vehicles (UAVs). Moreover, the necessity to control and navigate these vehicles has attracted much attention from researchers in this field. This is mostly due to the fact that the interactions between turbulent airflows apply complex aerodynamic forces to the system. Since the dynamics of a quadrotor are non-linear and the ...
