تطورت نظرية السوائل الكوانتية في السنوات الأخيرة بشكل كبير نظراً للطيف الواسع من الظواهر الطبيعية القابلة للتفسير بحدود من بارامترات هذه النظرية (بارامترات لانداو في سائل فيرمي). قمنا في خلال هذه الورقة بحل المعادلة الحركية للكثافة السبينية المطّورة مؤخراً بعد إضافة حدّ راشبا للترابط السبيني المداري و ذلك بتابعية بارامترات لانداو من المرتبة . و حسبنا أيضاً الطواعية المغناطيسية بعد أخذ تابع التأثير المتبادل بعين الاعتبار. ثمّ أوجدنا علاقة الطواعية المغناطيسية الناتجة علاقة التشتت لطاقة الاضطراب البنيوي (collective energy) المنتشر في السائل الكوانتي و ذلك بحساب الصيغ الموجية المختلفة (wave modes) عند أصفار التابع العقدي للطواعية المغناطيسية.
The theory of quantum liquids (quantum liquid theory) in the last few Years largely developed because of the brood spectrum of natural phenomenon relating to the limitation of parameters of the this (the parameters of the Landau Fermi liquid theory). We aim through this paper to resolve kinetic equation for the spin density. After adding Rashba term of spin-orbit coupling that belong to Landau parameters of orders ( 0,1). Also calculated the magnetic susceptibility also taking into account the mutual influence function,wich we have greeted from the collective perturbation energy. The propagation in quantum liquids by calculation(wave modes) at zeros complex function of magnetic susceptibility.

In this research, it has been studied the Fermi-Liquid density wave depending on
Landau theory. The kinetic equation has been solved using relaxation time approximation
at collision less condition. This is by expanding particle density function of
order Plus, Zero sound modes have been calculated and attenuation rate at low
temperatures.The results have been discussed and compared to the set ones and
the offered theory in this domain.
This research studies solving the linear second order difference
equation with variable coefficients.
For solving this equation we use two theorems and prove these theorems as well
as we use some definitions and main concepts .
In this study, an Interaction Function between quasi particles has been introduced
into an energy formula in Kinetic Equation of Quantum Plasmas. Such new type can be
used to study quasi Particles of Quantum Fermi Plasmas, since it contains quantum
term
that is correlated with Bohm Potential, when the mean inter-particle distance is of the same
order as the de-Broglie thermal wavelength. An interaction function between quasi
particles has been expressed using spherical Functions in three-dimensional space with
Landau’s spread coefficients for ℓ = 0 , 1 , 2 . Using such representation led to obtaining
the dispersion relation of the structural waves and its energy Spectrum in balanced local
condition. The use of Landau parameters in this study isconsidered new comparing to other
studies in this field. It allows us to get more generic and more precise dispersion relations
with new previously unknown spectrum energy in Quantum Fermi Plasmas.
In This Scientific Paper it had been studied the Effect of Ponderomotive Force on
Landau damping of electron Wave in dense quantum Plasmas, by Using quasi quantum
kinetic Equation, Using the Corrections due to both of quantum effects and Ponderomot
ive
Force, because of their necessity in Studying Wave Reflection inside Cavity Energy ,and
some Physical Properties of Plasmas, then comparing the Results to the other Conclusions
in this Field.
The main goal of the presented research in this paper is to find a general way to solve longitudinal vibration problems. This way must solve these problems in nonlinear elastic bar systems with a biological factor.
We applied longitudinal vibration
equations in a nonlinear elastic bar with biological factor, the bar material was taken non-linear. and solve the problem in a bar of finite length.
