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…
Refining Heuristic Predictors of Fractional Chern Insulators using Machine Learning
Oriol Mayné i Comas, André Grossi Fonseca, Sachin Vaidya +1
We develop an interpretable, data-driven framework to quantify how single-particle band geometry governs the stability of fractional Chern insulators (FCIs). Using large-scale exac…
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…
Symbolic Learning of Topological Bands in Photonic Crystals
Ali Ghorashi, Sachin Vaidya, Ziming Liu +4
Topological photonic crystals (PhCs) that support disorder-resistant modes, protected degeneracies, and robust transport have recently been explored for applications in waveguiding…
Quantized crystalline-electromagnetic responses in insulators
Sachin Vaidya, André Grossi Fonseca, Mark R. Hirsbrunner +2
We introduce new classes of gapped topological phases characterized by quantized crystalline-electromagnetic responses, termed "multipolar Chern insulators". These systems are char…
Noise immunity in quantum optical systems through non-Hermitian topology
Jamison Sloan, Sachin Vaidya, Nicholas Rivera +1
Multimode nonlinear optical systems are highly valued for their ability to withstand large amounts of optical power, transmit data with high bandwidth, perform physical computation…
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…
KAN: Kolmogorov-Arnold Networks
