New approach to the thermal Casimir force between real metals
The new approach to the theoretical description of the thermal Casimir force between real metals is presented. It uses the plasma-like dielectric permittivity that takes into account the interband transitions of core electrons. This permittivity precisely satisfies the Kramers-Kronig relations. The respective Casimir entropy is positive and vanishes at zero temperature in accordance with the Ne...
متن کاملTemperature Dependence of the Casimir Force Between Real Metals
Recently there have been two papers by a combined experimental and theoretical collaboration [1, 2] that have strongly criticized our work on the temperature dependence of the Casimir force between a spherical lens and a plate, both coated with real metals (Au for example) [3]. They criticize our work as being in conflict with fundamental thermodynamical requirements, particularly the third law...
متن کاملComment on “Surface-impedance approach solves problems with the thermal Casimir force between real metals”
In a recent paper Geyer, Klimchitskaya, and Mostepanenko [Phys. Rev. A 67, 062102 (2003)] proposed the final solution of the problem of temperature correction to the Casimir force between real metals. The basic idea was that one cannot use the dielectric permittivity in the frequency region where a real current may arise leading to Joule heating of the metal. Instead, the surface impedance appr...
متن کاملGeneralized plasma-like permittivity and thermal Casimir force between real metals
The physical reasons why the Drude dielectric function is not compatible with the Lifshitz formula, as opposed to the generalized plasma-like permittivity, are presented. Essentially, the problem is connected with the finite size of metal plates. It is shown that the Lifshitz theory combined with the generalized plasma-like permittivity is thermodynamically consistent.

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
