A polariton is a quasi-particle that arises from the coupling of an electronic dipole transition in a material with an applied electromagnetic field, such as a photon. It represents the localized response of matter to the interaction with light. Polariton behavior can be observed in phenomena like optical phonons and surface plasmons. Understanding polaritons is essential for exploring light-matter interactions in various materials. This concept is crucial in fields such as condensed matter physics and photonics.

Does anyone have experience or know what a "Polariton" is?

I have read some material on polaritons but I am not grasping it very well. Would someone like to attempt to explain it?
 
Physics news on Phys.org


an imaginary photon used to define the energy associated with interaction of photons with matter or otherwise interactions between two materials.
 


A polariton is a quasi-particle describing the (localized) response from the coupling of an elecrtonic dipole transition in a material with an applied electromagnetic field (i.e a photon). Examples are optical phonons and surface-plasmons.

Thread 'Time rondeau crystals, experimental observations'

A relative asked me about the following article: Experimental observation of a time rondeau crystal https://www.nature.com/articles/s41567-025-03028-y I pointed my relative to following article: Scientists Discovered a Time Crystal That Reveals a New Way to Order Time https://www.yahoo.com/news/articles/scientists-discovered-time-crystal-reveals-180055389.html This area is outside of my regular experience. I'm interested in radiation effects in polycrystalline material, i.e., grain...
