Emergence of millimeter-wave resonances in self-assembled ferroelectric metamaterials
Florian Bergmann, Peter Meisenheimer, Aiden Ross +26
Resonators are a key component in modern communications and computing. As demand and technological advances push component requirements into the terahertz regime, there is signific…
Optical Signature of Moiré Superlattices Formed by Twisted SrTiO Membranes
T. A. M. Ragib Shahriar, Fumikazu Murakami, Xing He +11
Moiré superlattices formed at the interfaces of mismatched lattices have attracted significant interest over the past decade due to their large tunability of band parameters and i…
Mechanical Control of Polar Order
Pushpendra Gupta, Peter Meisenheimer, Xinyan Li +5
BiFeO3 is a model multiferroic in which the ferroelectric polarization is coupled to ferroelastic lattice distortions, yet deterministic control of its domain structure remains lim…
Autonomous Algorithm Discovery for Ptychography via Evolutionary LLM Reasoning
Xiangyu Yin, Ming Du, Junjing Deng +3
Ptychography is a computational imaging technique widely used for high-resolution materials characterization, but high-quality reconstructions often require the use of regularizati…
Topological textures and emergent altermagnetic signatures in ultrathin BiFeO3
George Fratian, Maya Ramesh, Xinyan Li +23
Magnetoelectric multiferroics, materials with intrinsically coupled electric polarization and magnetic order, promise ultralow-power switching, nonvolatile memory, and energy-effic…
Discovery of a new weberite-type antiferroelectric: La3NbO7
Louis Alaerts, Jesse Schimpf, Xinyan Li +7
Antiferroelectrics are antipolar materials which possess an electric field-induced phase transition to a polar, ferroelectric phase and offer significant potential for sensing/actu…
