I'm fine with the idea that a right-handed circularly polarized light can excite electron and holes that has some handedness property. However, how can you assign those right-handed excited electron and holes to a specific valley? I mean the material itself (MoS2, for instance) is achiral. I feel like the different valleys shouldn't be able to tell handedness.
Hello Miss Laurien, I am Asghar Ali from Quaid-i-Azam University, Islamabad, Pakistan. I am doing my Postgraduate in Physics and my research also focus on Valleytronics. I saw your presentation on RUclips and learned a lot. Now i am having a hard time to derive Orbital Magnetic Moment in graphene paper "Valley-Contrasting Physics in Graphene: Magnetic Moment and Topological Transport" Can you kindly provide me with derivation equation below starting from tight binding hamiltonian. Thanks in advance
I am so confused on the purpose of valley pseudospin. Why is an addition DOF needed when the valleys are discinct by the real spin of electrons within them? i.e. K valley only can interact with RCP, which only excites "down" spin electrons?
Hi, it all sounded like a doctoral student in Brazil would you have any material related to Exciton valley depolarization in monolayer transition-metal dichalcogenides, to help . thanks
very nice talk for the beginners like me! Thank you for posting this.
Plz Upload such kind of video on this field

Thank you very much for the presentation.
Absolutely fantastic for a beginner to this field !!!
21:03 - took me a while, its "transition metal dichalcogenides" TMSs

Very nice overview. Just to bring to your attention: valleytronics can be done in graphene: Light-induced valleytronics in pristine graphene

우와 정말 좋은 설명입니다. 많은 도움이 되었습니다.
Thank you for your video. It helps a lot
Really nice talk!
thank you for talk & resources !

nicely explained. thanks
Is not clear about the odd and even nature of the magnetic moment and valleyspin in slide 10. Can you give more detail.
