Coupling of magnetic and lattice collective excitations in the 2D van der Waals antiferromagnet FePS
Kartik Panda, Itzik Kapon, Dumitru Dumcenco +3
We combine polarized infrared magneto-transmission and Faraday angle rotation measurements to map the collective excitations of the van der Waals antiferromagnet FePS. Below th…
Uniaxial strain-driven ferroelastic domain control in LaAlO3
Matthias Roeper, Robin Buschbeck, Jakob Wetzel +15
Multiferroic domain walls in functional oxides exhibit properties distinct from the bulk and are increasingly exploited as active elements in nanoelectronic and photonic devices. D…
Ultra-high THz-field-confinement at LaAlO3 twin walls
Jakob Wetzel, Javier Taboada-Gutiérrez, Matthias Roeper +13
The control and steering of light at nanometre length scales is crucial for the development of both fundamental science and nanophotonic technologies. Recent advancements have been…
Magneto-Optical Study of Chiral Magnetic Modes in NiI: Direct Evidence for Kitaev Interactions
Kartik Panda, Chaebin Kim, Daniel Bazyliansky +13
Bond-dependent magnetic interactions, particularly those described by the Kitaev model, have emerged as a key pathway toward realizing unconventional magnetic states such as quantu…
Tunable hyperbolic Landau-level polaritons in charge-neutral graphene nanoribbon metasurfaces
Kateryna Domina, Tetiana Slipchenko, D. -H. -Minh Nguyen +4
Magnetized charge-neutral graphene supports collective hybrid electronic excitations - polaritons - which have quantum origin. In contrast to polaritons in doped graphene, which ar…
Edge polaritons at metal-insulator boundaries in a phase separated correlated oxide
Weiwei Luo, Adrien Bercher, Claribel Dominguez +4
Correlated transition metal oxides, such as cuprates, nickelates, and manganites, are typically considered "bad metals", where high electromagnetic losses suppress the conventional…
