Abstract

在一个时间依赖者相互作用的存在的 Rashba 效果被考虑了。然后，如此的一个系统的时间进化被使用 Lewis-Riesenfeld 学习了动态不变、单一的转变方法。那么适当的动态不变、单一的转变，考虑系统被构造了以及一些特殊情况进入了在物理普通的这篇文章。

Rashba Effect in Presence of Time-Dependent Interaction

Hadi Sobhani, HASSAN HASSANABADI

Abstract Rashba effect in presence of a time-dependent interaction has been considered. Then time-evolution of such a system has been studied by using Lewis–Riesenfeld dynamical invariant and unitary transformation method. So appropriate dynamical invariant and unitary transformation according the considered system have been constructed as well as some special cases have come into this article which are common in physics.

Dynamical symmetry breaking in the Lewis–Riesenfeld oscillator

Neil J. Günther

Dynamical realization is given to the generator responsible for breaking the usual SU(3) invariance symmetry in the case of the Lewis–Riesenfeld time-dependent oscillator: H (t) = 1/2 𝒥3i[pipi+w2(t) qiqi]. This is achieved by finding a simple expression for the time-dependent Hamiltonian in the interaction picture: H=Ho+gH1. The breaking interaction is shown to transform as (6⊕6̄) of SU(3). Time-dependent dilations relate the broken Hamiltonian to the Lewis–Riesenfeld form. This scaling generates the algebra of the Weyl group and its role in oscillator noninvariance symmetries is considered.

Constraints on the choice of position dependent effective mass and external potential for the existence of Lewis-Riesenfeld invariance and quantum canonical transformation

Kalpana Biswas, Jyoti Prasad Saha, Pinaki Patra

Lewis-Riesenfeld -Ermakov's (LR) invariant method for the construction of time-dependent phase-space invariant is extended for the general quantum system with position-dependent effective mass (PDEM) Hamiltonian. It turns out that, only a specific class of PDEM and a particular class of external potentials will exhibit the LR-invariant operator in close form. Then we have determined a class of unitary time-dependent quantum canonical transformation for the concerned PDEM and external potentials so that an equivalent time-independent PDEM Hamiltonian is obtained.
