Excitons in Bulk and Layered Chromium Tri-Halides: From Frenkel to the Wannier-Mott Limit
Swagata Acharya, Dimitar Pashov, Alexander N. Rudenko +3
Excitons with large binding energies 2-3 eV in CrX are historically characterized as being localized (Frenkel) excitons that emerge from the atomic transitions…
First principles vs second principles: Role of charge self-consistency in strongly correlated systems
Swagata Acharya, Dimitar Pashov, Alexander N. Rudenko +3
First principles approaches have been successful in solving many-body Hamiltonians for real materials to an extent when correlations are weak or moderate. As the electronic correla…
Supercurrent decay in ballistic magnetic Josephson junctions
Hervé Ness, Ivan A. Sadovskyy, Andrey E. Antipov +2
We investigate transport properties of ballistic magnetic Josephson junctions and establish that suppression of supercurrent is an intrinsic property of the junctions, even in abse…
