چکیده
The behavior of a particle moving according to the laws quantum mechanics in field, which potential changes over time, is studied. method unitary transformations for solving temporal Schrödinger equation considered. reduced Hamiltonian system quantum-mechanical time-dependent obtained, as well total operator evolution such system. We find new version transformation, which, compared known ones, simplifies problem analytical form. This transformation associates linear model with time-dependent parameters and freeparticle Based on constructed operator, we consider wave packet dispersion. It shown that dispersion this same free particle. conclusion general result quantummechanical field timedependent potential.

متن کاملWhen 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 کاملTime-dependent analysis of carrier density and potential energy in spherical centered defect InGaAs/AlGaAs quantum dot (SCDQD)
Interaction and correlation effects in quantum dots play a fundamental role in defining both their equilibrium and transport properties. Numerical methods are commonly employed to study such systems. In this paper we investigate the numerical calculation of quantum transport of electrons in spherical centered defect InGaAs/AlGaAs quantum dot (SCDQD). The simulation is based on the imaginary time...

متن کاملQuantum response to time-dependent external field
Recently, explicit real time dynamics has been studied in various systems. These quantum mechanical dynamics could provide new recipes in information processing. Here, we study quantum dynamics under time dependent external field. In particular, we compare the thermal and quantum fluctuation in the transverse Ising model. Moreover we study other types of quantum fluctuations, e.g. effects of th...
