Accelerating Inverse Design of Optical Metasurfaces: Analytic Gradients of Periodic Green's Functions via Quasi-Modular Forms
Mingcan Qin, Yifeng Qin
The inverse design of nonlocal metasurfaces requires the precise optimization of lattice geometry to engineer spatial dispersion and high-Q resonances. However, gradient-based opti…

Geometric Control of Pairing: Universal Scaling of Superconductivity at KTaO3 Interfaces
Xueshan Cao, Meng Zhang, Yishuai Wang +3
The superconducting transition temperature Tc at KTaO3-based oxide interfaces exhibits a dramatic dependence on crystallographic orientation, yet a unifying principle has remained…

Universally enhanced superconductivity and coexisting ferroelectricity at oxide interfaces
Meng Zhang, Ming Qin, Yanqiu Sun +2
The coexistence of superconductivity and ferroelectricity is rare due to their conflicting requirements: superconductivity relies on free charge carriers, whereas ferroelectricity…
