Polar-vortex-driven interfacial strain coupling in PbTiO3/SrRuO3 Heterostructures
S. A. Raza, V. A. Stoica, H. Zheng +7
Interfacial coupling in oxide heterostructures is a central problem in condensed-matter physics, as it typically emerges at the atomic scale through local interactions mediated by…
A Dynamical Phase-Field Model for the Optical Properties of Ferroelectrics
Aiden Ross, Anya Frazer, Venkatraman Gopalan +1
Ferroelectric materials are promising platforms for controllable photonic devices because of the strong coupling between their spontaneous polarization and optical properties. Yet,…
Bilinear Flexo-Antiferrodistortive Coupling in Ferroelastics: Polar Twins, Antiphase Boundaries and Fingerprints of Alterelectricity
Eugene A. Eliseev, Anna N. Morozovska, Venkatraman Gopalan +1
Using the Landau-Ginsburg-Devonshire approach we show that the linear gradient-type coupling between the electric polarization vector and antiferrodistortive long-range order param…
Strong coupling between coherent ferrons and cavity acoustic phonons
Yujie Zhu, Jiaxuan Wu, Anna N. Morozovska +7
Coherent ferrons, the quanta of polarization waves, can potentially be hybridized with many other quasiparticles for achieving novel control modalities in quantum communication, co…
Embedded Ferroelectric Nanoclusters can drive Polarization Reversal in a Non-Ferroelectric Polar Film via the Proximity Effect
Anna N. Morozovska, Eugene A. Eliseev, Sergei V. Kalinin +3
Heterogeneous nucleation from defects dominates the electric field required for polarization switching of ferroelectrics. Here, we consider the switching of a nominally non-switcha…
Quantum Saturation of the Electro-Optic Effect
Aiden Ross, Sankalpa Hazra, Albert Suceava +4
Future quantum computing architectures require electro-optic materials that maintain a strong, stable performance at cryogenic temperatures. In conventional electro-optic materials…
