Quantum Numerical Control of Nuclei†#

Abstract

Quantum control of elementary particle at nucleon had already been investigated for a couple of decades at the frontier area both in quantum physics and system control. At the nucleus, a kind of control for particles motion had been considered in the form of Klein-Gordon-Schrödinger equation, which is a system describing the Yukawa interaction between nucleon (e.g. proton, neutron) and meson. The aim of this paper is trying to find an external force to act at one of the particles to change the particle from its ground state to reach its exciting state.

Quantum Optimal Numerical Controlling for Yukawa Interaction of Couple Heavy Particles

Quan‐Fang Wang

Beyond the controlling of molecules and atoms, quantum control step forward to a new era of achieving control at nucleus scale. This work is to attempt the investigation of quantum controlling with the interaction between two heavy particles (e.g. nucleon and meson). The interaction, which expressed as coupled Schrodinger and Klein-Gordon equations, will be the target of controlling. Experiment demonstration illustrate that theoretical study combining with computational control is effected to performance.

Quantum optimal control of nuclei in the presence of perturbation in electric field

Quan‐Fang Wang

The quantum optimal control of nuclei (nucleon and meson) in the presence of perturbations in control field is investigated. The nucleon and meson interaction is given by Klein–Gordon–Schrödinger systems with dissipative and damping terms. A rational physical model is proposed for controlling two particles. Suppose the amplitude of perturbation is bounded, optimal quantum control pairing are found theoretically and computationally. A stable semi-discrete algorithm is developed to execute computational simulations for illustrating the feasibility of theoretic control design.

Quantum numerical optimal control of nucleon and meson dissipative dynamical model

Quan‐Fang Wang, Chengyu Cao

A reasonable dissipative physical model is established for nucleons and meson dynamical system described by Klein-Gordon Schrödinger coupled equations. Using the laser pulse electric control to derive the initial ground state to target excited state will be considered in this paper. A stable semi-discrete approach is experimentally applied to realize the theoretical design of control searching. The perfect matched simulation results illustrated the feasibility of theoretical study, and provided the prediction for real laboratory experiments.

In physics and chemistry realms, the exciting quantum field would play a major role.Particularly, quantum control area should have significant and powerful development tendency. With a numerous attempts in a variety of fields, the extremely frontier area move forward to control elementary particles. Lasting effects must boost the appearing of breakthrough soonerafter. As is well known, a mount of milestone works lie on the controlling of atomic and molecules dynamics. Naturally, future researches will concentrate in quantum controlling at nucleus scale.
