Can high intensity laser excite surface plasma waves?
As we know, light in free space cannot excite plasma waves.
However, it is possible to get help from the prism, grating or surface modification. However, with the help of two high-intensity laser ...

Are energy levels of metal nanoparticles discrete?
I will start with the quote from the book: "Plasmonics Fundamentals and Applications" by Stefan Maier. In the very first page he says "Even metallic nanostructures down to sizes on the ...

Extremely strong peak around 10 eV energy of Aluminum crystal in an x-ray inelastic scattering experiment
I conducted an experiment where I measured Bragg reflection for two different atomic planes (200 and 400) of Aluminum crystal at an energy of 10 KeV. Then, in each of these two measurements I shifted ...

How to find plasmon from Landau-Silin equation?
In David Pine's Theory Of Quantum Liquids: Normal Fermi Liquids, it's said that we can find charged Fermi liquid has plasmon modes easily from Eq. (3.40), replicated as follows:
$$

Plasmon and The Orientation of the Plasma Oscillation
The electric field wave resulting from plasma oscillation can be broken down into the transverse and longitudinal components, whose frequencies are given by
$$\omega_{transversal} = \sqrt{c^2k^2+\...

Laser on metal surface: What happens in terms of photons, plasmons, phonons and their interactions?
I'm trying to better understand what exactly happens when a laser beam hits a surface (apart from reflection). Say I have a thick gold surface (could be coated with gold nanoparticles if that helps) ...

Confinement of electromagnetic field in coaxial cable
I wonder about the situation when we apply AC voltage or RF voltage on coaxial cable. Typically, the lateral dimension of coaxial cable is smaller than the wavelength of electromagnetic field in such ...

Can plasmon nanoparticles be displaced by EM field’s?
As at specific frequencies of light, a plasmonic nanoparticle’s electron cloud will predominately shift to one part of the material, will this cause the material to shift in that direction?

How do wave equations have an exponential solution involving wave vector and the propagation constant?
I hope you all are doing well!
I was trying to derive the propagation constant for the wave vector of the surface plasmons. I have uploaded the document below, which is the following:
Here , is the ...

Can someone help me in understanding what actually plasmons are?
This question might have been asked several times but I am confused on this topic. What actually are the plasmons? Do they only exist in the case of metals or they can be found even in semiconductors? ...

Using flat or thin glass for Surface Plasmon Resonance
SPR is typically created using prism with a thin gold film on the other end. I was wondering if I cut the triangular prism (using a glass cutter at home) into thinner slices, would this have an impact ...

What is the value for the plasmon frequency of intrinsic $\rm Si$?
I found some values for the plasma frequency $\omega_p$ of doped $\rm Si$, but not for intrinsic Si. Because of this, I tried to calculate it with
$$
\omega_p^2 = \frac{ne^2}{m_\text{eff}\ \epsilon_0\...

Golden quantum dots blinking and plasmons
I have been reading this article about golden QD as a way to avoid QD blinking. I understand that the surface plasmons here act as a nano antenna which strongly concentrates the light, but I don’t ...
