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…

Evaluating the Structural Basis for Polar Altermagnet Candidate Ca(Ru,Ti)O
Akash Saha, Yihuang Xiong, Vladimir A. Stoica +15
The interplay between polar and altermagnetic orders remains largely unexplored in the broader landscape of correlated electron systems. CaRuO has been proposed b…

Thermodynamic Theory of Linear Optical and Electro-Optic Properties of Ferroelectrics
Aiden Ross, Mohamed S. M. M. Ali, Akash Saha +4
Ferroelectric materials underlie key optical technologies in optical communications, integrated optics and quantum computing. Yet, there is a lack of a consistent thermodynamic fra…
