Recent research in nanophotonics for scintillation-based imaging has demonstrated promising improvements in scintillator performance. In parallel, advances in nanophotonics have en…
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…
Refining Heuristic Predictors of Fractional Chern Insulators using Machine Learning
Oriol Mayné i Comas, Oriol Mayné i Comas, André Grossi Fonseca +4
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…
Tunable Nanophotonic Devices and Cavities based on a Two-Dimensional Magnet
Ahmet Kemal Demir, Luca Nessi, Sachin Vaidya +3
Central to the field of nanophotonics is the ability to engineer the flow of light through nanoscale structures. These structures often have permanent working spectral ranges and o…
End-to-end design of multicolor scintillators for enhanced energy resolution in X-ray imaging
Seokhwan Min, Seou Choi, Simo Pajovic +5
Scintillators have been widely used in X-ray imaging due to their ability to convert high-energy radiation into visible light, making them essential for applications such as medica…
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…
