Excitons in van der Waals magnetic materials
Pratap Chandra Adak, Florian Dirnberger, Swagata Acharya +3
Two-dimensional magnetic semiconductors provide a unique materials platform in which long-range magnetic order coexists with strongly bound excitons. Because excitonic states and m…

Magnon-mediated exciton-exciton interaction in a van der Waals antiferromagnet
Biswajit Datta, Pratap Chandra Adak, Sichao Yu +17
Excitons are fundamental excitations that govern the optical properties of semiconductors. Interacting excitons can lead to various emergent phases of matter and large nonlinear op…

Moiré exciton polaron engineering via twisted hBN
Minhyun Cho, Biswajit Datta, Kwanghee Han +11
Twisted hexagonal boron nitride (thBN) exhibits emergent ferroelectricity due to the formation of moiré superlattices with alternating AB and BA domains. These domains possess ele…
