Magnetic control of an exciton-polariton condensate in a van der Waals magnet
Heng Zhang, Niloufar Nilforoushan, Christian Weidgans +12
Quasiparticle condensates are among the most spectacular solid-state manifestations of quantum physics. Coupling macroscopic real-space wavefunctions to additional degrees of freed…
Role of photonic interference in exciton-mediated magneto-optic responses
Güven Budak, Güven Budak, Christian Riedel +5
Coupled optical and magnetic excitations can give rise to remarkably strong magneto-optic responses. This is particularly evident in van der Waals magnets, such as the antiferromag…
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…
Distinct Magneto-Optical Response of Frenkel and Wannier Excitons in CrSBr
Maciej Smiertka, Michal Rygala, Katarzyna Posmyk +10
This study shows that CrSBr hosts Frenkel-like and Wannier-Mott-like excitons whose distinct spatial character explains their contrasting sensitivity to magnetic order and lattice…
Exciton transport driven by spin excitations in an antiferromagnet
Florian Dirnberger, Sophia Terres, Zakhar A. Iakovlev +5
A new class of optical quasiparticles called magnetic excitons recently emerged in magnetic van der Waals materials. Akin to the highly effective strategies developed for electrons…
Lithium Intercalation in the Anisotropic van der Waals Magnetic Semiconductor CrSBr
Kseniia Mosina, Aljoscha Söll, Jiri Sturala +9
Alkali metal intercalation is an important strategy for doping van der Waals materials. Lithium, in particular, was shown to achieve exceptional charge carrier densities, reaching…
