纳米粒子哈密顿量的矢量相干态

Vector coherent states for nanoparticle Hamiltonians

Isiaka Aremua, Mahouton Norbert Hounkonnou

摘要:

本文的第一部分研究了与$N$玻色子模相关的$M$费米型模系统的矢量相干态的构造。然后遵循一个概括的哈密顿描述的平移运动的质心的纳米粒子。后者为纳米晶体中的电子能量弛豫提供了一种新的机制,目前在凝聚态物理中得到了深入研究。所涉及的哈密顿系统的有限退化也进行了研究。所定义的矢量相干态满足连续性、恒等式分解、时间稳定性和作用恒等式等相关数学性质。

英文摘要:

The first part of this work deals with a formalism of vector coherent states construction for a system of $M$ Fermi-type modes associated with $N$ bosonic modes. Then follows a generalization to a Hamiltonian describing the translational motion of the center of mass of a nanoparticle. The latter gives rise to a new mechanism for the electronic energy relaxation in nanocrystals, intensively studied today in condensed matter physics. Finite degeneracies of the involved Hamiltonian systems are also investigated. The defined vector coherent states satisfy relevant mathematical properties of continuity, resolution of identity, temporal stability and action identity.
