Vision-Language Agents for Active Perception in Optics Laboratories
Ryan Lopez, Sachin Vaidya, Seou Choi +2
Vision-language models (VLMs) are increasingly being used in scientific workflows, but their ability as agents to directly control laboratory experiments from visual feedback remai…
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…
End-to-End Optimization of Incoherent Imaging for Classification Under Detector-Limited Readout
Archer Wang, Joshua Chen, Sachin Vaidya +1
End-to-end co-optimization of optical front-ends (e.g. metasurfaces) and neural network back-ends has been widely applied to imaging tasks, yet a formalism characterizing when and…
Non-Hermiticity-induced chirality imbalance of Weyl Landau levels
Sachin Vaidya, Alaa Bayazeed, André Grossi Fonseca +3
Weyl semimetals obey a global chirality constraint: the net chiral topological charge and any associated chiral spectral flow must vanish, as required by the Nielsen-Ninomiya theor…
Hybrid Nanophotonic Scintillators for Enhanced X-ray Absorption, Emission, and Time Resolution
Seou Choi, Sachin Vaidya, Avner Shultzman +3
Scintillators convert ionizing radiation into visible photons, enabling applications from cosmic ray detection to medical imaging. Two independent strategies for improving scintill…
A Framework for Closed-Loop Robotic Assembly, Alignment and Self-Recovery of Precision Optical Systems
Seou Choi, Sachin Vaidya, Caio Silva +4
Robotic automation has transformed scientific workflows in domains such as chemistry and materials science, yet free-space optics, which is a high precision domain, remains largely…
Wavefront Engineering for Scintillation-Based Imaging
Joshua Chen, Sachin Vaidya, Simo Pajovic +7
Recent research in nanophotonics for scintillation-based imaging has demonstrated promising improvements in scintillator performance. In parallel, advances in nanophotonics have en…
