Manipulation of localized excitons in CrPS by temperature and magnetic field
Dipankar Jana, Swagata Acharya, Amit Pawbake +9
Layered van der Waals magnetic semiconductors provide a versatile platform for exploring excitonic phenomena intertwined with spin and lattice degrees of freedom, enabling excitons…
Towards on-chip nascent all-van-der-Waals polarization optical components for nanoscale photonic applications
Dmitrii Litvinov, Ilia Begichev, Iakov Reznikov +8
The integration of polarization-control elements into nanoscale photonic circuits remains a central challenge for modern on-chip optical technologies, which call for continuous min…
Probing the temperature dependence of dielectric function of ternary transition metal dichalcogenides: towards thermo-driven ultrathin photonic components
Artsruni Margaryan, Maria Levonyan, Maksim Sargsyan +4
Transition metal dichalcogenides (TMDs), along with their ternary derivatives, have attracted considerable attention mostly due to pronounced excitonic resonances emerging in visib…
Emergent Fermi polarons in Dirac materials
Xin Chen, Eugen Dizer, RafaÅ OÅdziejewski +3
We investigate band-structure effects on the absorption spectra of quantum impurities in Dirac materials. We uncover the formation of novel quasiparticles -- Dirac-Fermi polarons -…
Untangling 3D atomic reconstruction in twisted bilayer 2D crystals via dark field transmission electron microscopy
Pankaj Kumar, Michel Bosman, Nikolai Lavrentev +4
Reconstruction of the atomic crystal structure in twisted 2D materials has been demonstrated to be responsible for multiple exciting phenomena in van der Waals heterostructures, fr…
Composable Crystals: Controllable Materials Discovery via Concept Learning
Nian Liu, Yuwei Zeng, Ryoji Kubo +7
De novo crystal generation, a central task in materials discovery, aims to generate crystals that are simultaneously valid, stable, unique, and novel. Existing methods mainly rely…
