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…
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…
Probing Topological Surface States and Conduction via Extended Defects in (BiSb)Te Films
Abby Liu, Armando Gil, Moon-ki Choi +10
(BiSb)Te alloys are non-degenerate topological insulators (TIs) whose Dirac point (DP) can be tuned within the bulk bandgap by varying the composition, effectiv…
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…
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…
