Emergence of millimeter-wave resonances in self-assembled ferroelectric metamaterials
Florian Bergmann, Peter Meisenheimer, Aiden Ross +26
Resonators are a key component in modern communications and computing. As demand and technological advances push component requirements into the terahertz regime, there is signific…
Harnessing the polar vortex motion in oxide heterostructures
Pushpendra Gupta, Mohit Tanwani, Qi Xu +7
Polar topology, an analogue of the magnetic topology, serves as a large playground for exotic physical phenomena with a wide range of multifunctional applications. Polar vortices a…
Terahertz-field activation of polar skyrons
Huaiyu Wang, Vladimir Stoica, Cheng Dai +27
Unraveling collective modes arising from coupled degrees of freedom is crucial for understanding complex interactions in solids and developing new functionalities. Unique collectiv…
Emergence of Transverse Dielectric Response in Ferroelectric Dielectric Heterostructures
Fernando Gómez-Ortiz, Ramamoorthy Ramesh, Javier Junquera
We report the emergence of a transverse dielectric response in PbTiO/SrTiO superlattices hosting polar vortex structures. Using second-principles simulations, we find t…
Symmetry-based phenomenological model for magnon transport in a multiferroic
Isaac A. Harris, Sajid Husain, Peter Meisenheimer +9
Magnons carriers of spin information can be controlled by electric fields in the multiferroic BiFeO (BFO), a milestone that brings magnons closer to application in future devic…
