Semiconductor Exciton Polaritons

We explain underlying physics of exciton-polariton formation in a semiconductor microcavity. Fascinating fundamental effects can be observed in microcavity polariton systems, such as stimulated parametric scattering, non-equilibrium Bose-Einstein condensation and superfluidity. We have a large research activity aimed at understanding and exploiting the light-matter interactions in exciton-polariton systems: ldsd.group.shef.ac.uk/research...

[@YUVRAJMOT]

Physics, when taught this way, is the most interesting thing to explore!! Hats off to this tutorial.

[@Yudirada]

The animation is so epic...

[@frank841220]

Are there more videos would be uploaded? Your physics animations all are so epic!!!

[@quantumlightuniversityofsh5496]

Thank you! Yes, we are working on a few more at the moment. We don't have a final release date though, but we expect the next one to be out in a few months time. So, please stay tuned!

[@Shallowandpedantic42]

I'm not a physics major. But I was able to understand this very well. Thank you for simplifying this complex topic.

[@ashish19]

Amazing way to teach tough concepts.

[@ARBB1]

This is absolutely fantastic. The god-like editing work and animations, as well as the concise voiceover make this one of the best physics videos I've seen.

[@Trotskisty]

A lot of hard work clearly went into making this crystal clear video. Kudos.

[@1murkeybadmayn]

currently studying semiconductors, love this animation.

[@yusongbai17]

Such an intuitive and clear explanation! Absolutely amazing!

[@theo16s]

This animated illustration is simply amazing

My mind is blown away by this explanation. Simply great!

[@Eldorado1239]

Hello, and, again, welcome to the Aperture Science Computer-Aided Enrichment Center.

[@deborahsorrill3119]

This is a wonderful video. It keeps you engaged and before you know if you have an understanding of a complex phenomenon. I am actually going to watch it again!

[@laras.g.3048]

This video is incredible, it manages to communicate the basic knowledge and ideas and the animation is so pleasurable to see. Congratulations and thank you!

[@hirandcurious]

The animations were really great. I just heard the name in one of my courses and looked for a video that explains it bit more. But to be honest, I didn't expect such a nice video about polaritons.

[@no.20karthigak68]

Good animation to explain in the last

[@jonathanz2522]

Right during my revision time..Great explanation

[@dibyanshdash4854]

By far the best animation for a physics topic I've seen

[@mrigank8822]

holy fuck that's beautiful animation

[@asaadumair1]

You made it look like a very concept. Hats off!

[@kael7953]

I subscribed without hesitation

[@Guitar.Rookie]

Superfluid Mindstate 😌👌💫💧⚡

[@dhimanroy1671]

Just want to give a red Salute to the team who made this visual representation! Best science based animation ever seen!!

[@SiNiSTASMiRK]

I thought I knew most of what there is to know from the aether of KZbin culture. But my mind just fucking exploded.

[@geraldzhou2128]

Thank you for making it more easily to understand.

[@crickcraze8706]

it was the best scientific explanation i had seen so far,

[@samapanbhadury6228]

Amazing animation made it so easy to understand the concept. Please make more videos like these.

[@snapo1750]

Thank you so much for explaining it in a as simple way as possible...

[@fang-djamal]

Great animation. My understanding of this phenomenon has been elusive until now. ^^

[@lacusrengoku5087]

I'm taking a course on nano photonics. Not a physics background, so has been struggling with the microcavity process. This video is life-saving!

[@SystemicCreative]

Beautifully explained, great video, thanks.

[@jakecass43]

Nice visuals and editing.

[@JuiceExMachina]

tbh I found the "glitchy" design a little annoying, but ultimately this video managed to make me understand polaritons. I have read many other sources on the matter and didnt understand it, but this video of all things was the source that did it. So great job 👍

[@meowed]

Really great videos! Wish you could post more!

[@ariqrizqullah9842]

can't debate the animation is so dope! and also clearly explanation, Thanks!

[@MindaugasSarpis]

This is very very good! We want more from you guys! : D Keep it going.

[@mjunaid5760]

Thank you so much for such best animated explanation 💖

[@marxregis]

Great explanation!

[@rishabhgupta7264]

why there are so few subscribers? This seemed to me as a most epic explanation of a polariton..

[@bruceleang9773]

Amazing Video!

[@rogertormoqueralt2180]

amazing video effects!! a bit more of theory would be nice

[@fmcore]

Thank you for the efforts to produce this beautiful video but it needs more explanation on the physics more than on the music.

[@rumpafatema5703]

breath taking!

[@anteconfig5391]

Amazing. More people need to teach in this fashion. more I say. more.

[@marcoponts8942]

The animations is awesome! What program are you using? Please tell! It looks aaamazing!

[@xiaoli7565]

Awesome job!

[@JonnhyW]

great work

[@jayalshehri7519]

Excellent ! many thanks

[@BeginnerDad]

I doubt my 8-year-old understands physics much, but he also loved that video. Perhaps this is how the quantum world could be introduced at school, with an animation of a guitar string! :)

[@galihramadanasuwito8088]

great animation!!!

[@mohamedzaher7150]

Great Video

[@crazyLocko]

[@hariharanramamurthy9946]

great animations can you do more videos

[@lightspeed6302]

Love anything about quantum mechanics

[@iramta5974]

amazingggg explanation. Thank you so much for making such a wonderful video lesson for us. I got this exciton concept for the very first time like this. so epic

[@antoniocarlos895]

Excellent!

[@germanginger4649]

So, what would theoretically happen if the atoms in the Quantum Well were negatively charged? Would it be the same reaction or an increase in energy release?

[@gusstavv]

That escalated quickly!! :o

[@randomvideos3628]

so there is no loss of energy when the electron and vacancy orbit each other?

[@bhautikshingala27]

Animation is so beautiful❤❤❤ How make this.... please reply

[@mauroariascontreras9284]

super bello! gracias =)

[@nikhilsen9007]

Dil jit liya si tussi...

[@sagarrawal8332]

I am totally baffled by this amazing masterpiece animation. Thank you so much. can you tell me what is difference between plasmon and polaritons?

[@quantumlightuniversityofsh5496]

Thanks a lot! To answer your question, in general, polariton is a quasi-particle arising from the strong coupling of light (photons also described as electromagnetic waves) with some kind of electric or magnetic dipoles in the matter. In our video, we talked about exciton-polaritons -- polaritons which emerge from the strong coupling of photons and excitons, which are a type of dipole, inside a microresonator. Exciton-polariton can emerge also without the resonator but are a lot harder to observe and lack some interesting properties. When you refer to plasmons, do you mean 'surface plasmon-polaritons'? These occur when light (photons) strongly couples to dipoles of electric charges at the interface of a conductor and a dielectric (such as a metal-air interface). 'Surface plasmons' on their own are simply the oscillations (dipoles) emerging on the interface. Finally, 'plasmons' are quanta of oscillation of electric density inside a plasma. These three different 'plasmons' can be sometimes confused.

[@cosmicyoke]

could this be done with much lower frequencies?

[@sMVshortMusicVideos]

That was tremendous.
