Bound states of electrons with soliton-like excitations in thermal systems - adiabatic approximations
We study the bound states of electrons with solitonic excitations in one and two-dimensional atomic systems. We include Morse interactions between the atoms in a temperature range from low to physiological temperatures. The atoms are treated by classical Langevin equations. In a first approach, th...

We study the bound states of electrons with solitonic excitations in one and two-dimensional atomic systems. We include Morse interactions between the atoms in a temperature range from low to physiological temperatures. The atoms are treated by classical Langevin equations. In a first approach, the places of compressions are visualized by drawing the overlap of the densities of the core electrons.

Ми вивчаємо зв’язанi стани електронiв iз солiтонними збудженнями в одно- та двовимiрних системах. Розглядаються взаємодiї мiж атомами типу Морзе у температурному iнтервалi вiд низьких до фiзiологiчних температур. Атоми розглядаються на основi класичних рiвнянь Ланжевета. У першому пiдходi мiсця стиску вiзуалiзуються шляхом виявлення областi перекриття густин основних електронiв. Далi на основi аналiзу руху вiльних електронiв щодо атомiв дослiджується ефект нелiнiйних коливань. У наближеннi сильного зв’язку вивчено зв’язану класичну i квантово-механiчну динамiку електронiв на ґратцi. Крiм того, базуючись на аналiзi спектру енергiй та канонiчного розподiлу, розглянуто формування солелектронiв, тобто динамiку зв’язаних електрон-солiтонних станiв в адiабатичних наближеннях. 2009 Article Bound states of electrons with soliton-like excitations in thermal systems - adiabatic approximations / W.

We study the bound states of electrons with solitonic excitations in one and two-dimensional atomic systems.
We include Morse interactions between the atoms in a temperature range from low to physiological
temperatures. The atoms are treated by classical Langevin equations. In a first approach, the places of compressions
are visualized by drawing the overlap of the densities of the core electrons. Then we study the effect
of nonlinear vibrations on the added, free electrons moving on the background of the atoms. We study the
coupled classical and quantum-mechanical dynamics of the electrons on the lattice in tight-binding approximation
(TBA). Further we consider the formation of solectrons, i. e., dynamic electron-soliton bound states in
adiabatic approximations based on the energy spectrum and the canonical distribution. |
