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…
Good plasmons in a bad metal
Francesco L. Ruta, Yinming Shao, Swagata Acharya +12
Correlated materials may exhibit unusually high resistivity increasing linearly in temperature, breaking through the Mott-Ioffe-Regel bound, above which coherent quasiparticles are…
Giant exchange splitting in the electronic structure of A-type 2D antiferromagnet CrSBr
Matthew D. Watson, Swagata Acharya, James E. Nunn +6
We present the evolution of the electronic structure of CrSBr from its antiferromagnetic ground state to the paramagnetic phase above T_N=132 K, in both experiment and theory. Low…
Quasiparticle band structure and excitonic optical response in V2O5 bulk and monolayer
Claudio Garcia, Santosh Kumar Radha, Swagata Acharya +1
The electronic band structure of VO is calculated using an all-electron quasiparticle self-consistent (QS) method, including electron-hole ladder diagrams in the scree…
