Three-dimensional confinement of light in photonic crystals without bandgaps
Manxi Shi, Sachin Vaidya, Ali Ghorashi +2
We demonstrate that confinement of light in three dimensions is possible in photonic crystals without a complete photonic bandgap. Our approach exploits symmetry-protected quadrati…
Supercollimating photonic crystal scintillators
Seou Choi, Sachin Vaidya, Charles Roques-Carmes +1
Scintillators convert X-ray energy into visible or near-visible photons, enabling applications in high-energy particle detection and X-ray imaging. Increasing scintillator thicknes…
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…
Classification of Fragile Topology Enabled by Matrix Homotopy
Ki Young Lee, Stephan Wong, Sachin Vaidya +2
The moire flat bands in twisted bilayer graphene have attracted considerable attention not only because of the emergence of correlated phases but also due to their nontrivial topol…
Large-scale self-assembled nanophotonic scintillators for X-ray imaging
Louis Martin-Monier, Simo Pajovic, Muluneh G. Abebe +9
Scintillators are essential for converting X-ray energy into visible light in imaging technologies. Their widespread application in imaging technologies has been enabled by scalabl…
