CLUSTER: Derivative-free optimization of smooth functions with parameter-change costs
Serena Landers, Sahil Pontula, Shiekh Zia Uddin +3
We introduce the CLUSTER algorithm (\textbf{c}oordinate-\textbf{l}evel \textbf{u}pdate \textbf{s}trategy for \textbf{t}rust-region step \textbf{e}valuation \textbf{r}efinement) for…
Exceptional topology on nonorientable manifolds
J. Lukas K. König, Kang Yang, André Grossi Fonseca +3
We classify gapped phases and characteristic nodal points of non-Hermitian band structures on two-dimensional nonorientable parameter spaces. Such spaces arise in a wide range of p…
Gradient-based search of quantum phases: discovering unconventional fractional Chern insulators
André Grossi Fonseca, Eric Wang, Sachin Vaidya +3
The discovery and understanding of new quantum phases has time and again transformed both fundamental physics and technology, yet progress often relies on slow, intuition-based the…
AI-Driven Robotics for Optics
Shiekh Zia Uddin, Sachin Vaidya, Shrish Choudhary +5
Optics is foundational to research in many areas of science and engineering, including nanophotonics, quantum information, materials science, biomedical imaging, and metrology. How…
