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…
Electron-Phonon Coupling in Many-Body Perturbation Theory: Developments within the Quasiparticle Self-Consistent GW approximation and LMTO Formalism
Savio Laricchia, Casey Eichstaedt, Dimitar Pashov +1
The calculation of electron-phonon (e-ph) coupling from first principles is a topic of great interest in materials science, offering a robust, non-empirical framework to understand…
Self-consistent quasi-particle and hybrid functional calculations for Al/InAs/Al heterojunctions: band offset and spin-orbit coupling effects
H. Ness, F. Corsetti, D. Pashov +4
The electronic structure of surfaces and interfaces plays a key role in the properties of quantum devices. Here, we study the electronic structure of realistic Al/InAs/Al heterojun…
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…
