Spin-quenching in molecule-transition-metal-dichalcogenide heterostructure through inverse proximity effect
Swagata Acharya, Dimitar Pashov, Daphne Lubert-Perquel +2
A functional heterostructure is central to integrated circuitry in quantum photonics, optoelectronics, neuromorphic computing, spintronics, and straintronics. Recently, heterostruc…
Origin of metal-insulator transition in rare-earth Nickelates
Swagata Acharya, Brooks Tellekamp, Jerome Jackson +4
Rare-earth nickelates RNiO3 (R=rare-earth element) exhibit three kinds of phase transitions with decreasing temperature: a structural transition from a pseudo-cubic to a monoclinic…
Excitonic optical interface for GHz-THz collective excitations in a van der Waals magnet
Sophie Bork, Richard Leven, Vincent Wirsdörfer +9
Collective spin and lattice excitations in quantum materials span energy scales from GHz to THz, yet establishing a unified optical interface for these modes remains a central chal…
Quasiparticle Description of Angle-Resolved Photoemission Spectroscopy for SrCuO2
Dimitar Pashov, Casey Eichstaedt, Swagata Acharya +1
SrCuO2 has long been considered a near-archetypal realization of a quasi one dimensional (1D) system of interacting electrons with short-range interactions. Within this framework,…
Deconstruction of the anisotropic magnetic interactions from spin-entangled optical excitations in van der Waals antiferromagnets
Dipankar Jana, Swagata Acharya, Milan Orlita +5
Magneto-optical excitations in antiferromagnetic d systems can originate from a multiplicity of light-spin and spin-spin interactions, as the light and spin degrees of freedom can…
Challenges and opportunities in proximity-driven exciton-spin engineering in van der Waals heterostructures
Mushir Thodika, Dimitar Pashov, Igor Zutic +2
van der Waals heterostructures consisting of transition metal dichalcogenides (TMDs) and two-dimensional (2D) magnets offer a versatile platform to study the coexistence and transf…
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…
