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. Density functional theory (DFT) within the…
Defect Control via Cu Enrichment Enhances Multifunctional Properties in the Polar Semiconductor Cu1+xMn1-ySiTe3
Subrata Ghosh, Yu Liu, Saugata Sarker +15
Polar materials have recently attracted significant interest due to their rich multifunctional properties. The chalcogenide polar semiconductor Cu1-xMn1+ySiTe3 (Cu-deficient) is an…
Switchable Polarization in an A-site Deficient Perovskite through Vacancy and Cation Engineering
Suguru Yoshida, Olivier Hernandez, Jinsuke Miyake +7
While defects are unavoidable in crystals and often detrimental to material performance, they can be a key ingredient for inducing functionalities when tailored. Here, we demonstra…
Probing Hidden Symmetry and Altermagnetism with Sub-Picometer Sensitivity via Nonlinear Transport
Subin Mali, Yufei Zhao, Yu Wang +8
X-ray and neutron diffraction are foundational tools for determining crystal structures, but their resolution limits can lead to misassignments, especially in materials with subtle…
Colossal Cryogenic Electro-Optic Response Through Metastability in Strained BaTiO Thin Films
Albert Suceava, Sankalpa Hazra, Aiden Ross +14
The search for thin film electro-optic (EO) materials that can retain superior performance under cryogenic conditions has become critical for quantum computing. Barium titanate thi…
Quantitative Nonlinear Optical Polarimetry with High Spatial Resolution
Albert Suceava, Sankalpa Hazra, Jadupati Nag +8
Nonlinear optical microscopy such as in the optical second-harmonic generation (SHG) modality has become a popular tool today for probing materials in the physical and biological s…
The Influence of Electric Field on the Anisotropic Dispersion of the Flexocoupling Induced Phonons and Ferrons in Van der Waals Ferrielectrics
Anna N. Morozovska, Eugene A. Eliseev, Yujie Zhu +4
As has been shown recently, the influence of the flexoelectric coupling (shortly "flexocoupling") on the fluctuations of electric polarization and elastic strains can lead to the p…
Euclideanization without Complexification of the Spacetime
Nicole Drew, Venkatraman Gopalan, Martin Bojowald
Minkowski spacetime can be mapped by a series of projections in a higher-dimensional spacetime to a Euclidean space, constituting a process of Euclideanization shown here in detail…
Chemically-Disordered Transparent Conductive Perovskites with High Crystalline Fidelity
Saeed S. I. Almishal, Pat Kezer, Yasuyuki Iwabuchi +16
This manuscript presents a working model linking chemical disorder and transport properties in correlated-electron perovskites with high-entropy formulations and a framework to act…
A Thermodynamic Theory of Proximity Ferroelectricity
Eugene A. Eliseev, Anna N. Morozovska, Jon-Paul Maria +2
Proximity ferroelectricity has recently been reported as a new design paradigm for inducing ferroelectricity, where a non-ferroelectric polar material becomes a ferroelectric by in…
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…
Untangling individual cation roles in rock salt high-entropy oxides
Saeed S. I. Almishal, Jacob T. Sivak, George N. Kotsonis +10
We unravel the distinct roles each cation plays in phase evolution, stability, and properties within Mg1/5Co1/5Ni1/5Cu1/5Zn1/5O high-entropy oxide (HEO) by integrating experimental…
Shape-Optimized Electrooptic Beam Scanners: Experiment
Jennifer C. Fang, M. J. Kawas, J. Zou +3
A new horn-shaped electrooptic scanner is described with significantly improved scanning sensitivity over rectangular-shaped devices. In the new device, the shape of the scanner is…
