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…
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…
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…
