I'm assuming that the particle is moving freely between two "barriers" distant 10 x 140 picometers (≈ 1 x 10-9m). The quantized energies of an electron particle "in a box" are: En=n2h28mL2En=n2h28mL2 with n=1,2,.n=1,2,. ...
Moreover, the b.t. is written as the mean value of a quantity that is called boundary quantum force, f (B). Thus, the Ehrenfest theorem for a particle-in-a-box can be completed with the formula .doi:10.1007/s12043-013-0517-4SALVATORE DE VINCENZO...
A particle in a box has the following wave function: (a) Is energy well defined? Why or why not? What is the expectation value for E? (b) Is momentum well defined? Why or why not? What is the expectation value? (c) Use the followin...
The energy spectrum formula in the Klein zone is surprisingly very simple and independent of the depth of the well. This implies that the same solution is also valid for the potential box (infinitely deep well). In the nonrelativistic limit, the well-known energy spectrum of a particle in a...

Particle Swarm Optimization (PSO) algorithms are widely used in a plethora of optimization problems. In this chapter, we focus on applications of PSO algorithms to optimization problems arising in the theory of wave scattering by inhomogeneous media. Mor
Over the years, a wide range of Janus particle production routes have been developed, resulting in a variety of particle types, as reviewed extensively in literature [28–33]. Depending on the production method, different particle shapes can be produced, ranging from spheres (Fig. 8.1A), over...
In the simultaneous optimization of multiple objectives, how to balance convergence promotion and diversity preservation in the evolutionary process is a key and challenging problem. In this research, a hyperplane-assisted multi-objective particle swarm optimization with a twofold proportional assignment str...
