Thermodynamics of Ferroelectric and Optical Properties in KNbO3
Aiden Ross, Venkatraman Gopalan, Long-Qing Chen
Potassium niobate (KNbO3) is a prototypical perovskite ferroelectric with large electro-optic and nonlinear optical responses, high optical damage thresholds and a rich sequence of…
Theory of terahertz pulse transmission through ferroelectric nanomembranes
Yujie Zhu, Aiden Ross, Xiangwei Guo +3
An analytical model is developed to predict the temporal evolution of the lattice polarization in ferroelectric nanomembranes upon the excitation by a terahertz (THz) electromagnet…
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…
Flexocoupling-induced phonons and ferrons in van der Waals ferroelectrics
Anna N. Morozovska, Eugene. A. Eliseev, Oleksiy V. Bereznikov +7
The contribution of flexoelectric coupling to the long-range order parameter fluctuations in ferroics can be critically important to the ferron dispersion and related polar, pyroel…
