Isn't it simply the Fourier transform of the distribution of nano-droplets induced by the fog? If size distribution of droplets is quite uniform. Main weakness of this idea is: the scattering to far field has to be with a infinite focus point. Sounds contradictory. Open to comments! :)...

Good evening, You may also have some emission of photons from the molecule. Your molecule interacts via Coulomb field with the surface and affects the electron-hole, yes. I think it may be named the Fano problem. It is however, not a dissipative channel. Concerning the vibration relaxation...

Hi, You can use a client instead: FileZilla or WinSCP. All the best, Thibault

Physicist in laser-matter interaction Specialized in nanostructure formation induced by intense laser illumination Interested by quantum electrodynamics for laser-solid interaction

Oh, so you may take into account the insane costs of education in USA and UK ($xx,xxx per year). In Europe, most of countries make pay something more reasonable, like xxx € per year. Depending on your marks and network, you can choose on the Shanghai ranking. Pragmatically: the higher the better.

Hot fields can be found in high impact factor journals. But really hot fields are not published yet, and may appear in the next weeks! To guess the really hot topics, you would have to build your own intuition. To build it, just keep reading and preparing publications. Then, step by step, you...

In general, I would find the effect of material-dependent pressure on the optical properties of materials by two ways. (i) It can be computed from first principles using Density Functional Theory. (ii) There are also some experimental measurements which propose some fitted functions for a...

(i) In a PN junction, I would say that yes, the principle is to create a space charge, inducing a permanent electric field to animate the electrons for generating a light-induced current. (ii) Light generated carriers can also excited via intense laser irradiation, where their amount become...

Good evening, For the quantum information, I would suggest to go into quantum photonics. It is clear that quantum computers will be working with photonics on chips and that language of the future computers is not yet defined. If I may allow myself to promote my favorite topic, I would suggest...

No. The time delay between two collisions is defined by τ. "Time before next collision" - "time since last collision" = τ. It's not more complex than that...

But it is rather hard to understand if we might use complex or real optical index sometimes... Examples: 1/ Snell-Descartes law in complex gives different results than with real indexes. So, which one is true ? 2/ Link between optical index and dielectric function. Usually, n=sqrt(epsilon)...

I would like to catch your attention to the following recent article. http://prl.aps.org/abstract/PRL/v106/i19/e193003 The abstract is the following. "We report the direct observation of the nonreciprocity of the velocity of light, induced by electric and magnetic fields. This bilinear...

Hello Xian, Concerning 2), I found this interesting abstract. http://prola.aps.org/abstract/PR/v104/i6/p1760_1 Concerning 3), to my knowledge, it is similar. For most of the points, I found a good book which could give you some deep answers: HM Nussezveig, Causality and dispersion...
