Vacuum Fluctuation-Induced State Switching in Degenerate Optical Parametric Oscillators
Yihao Huang, Seou Choi, Rom Simovitch +5
Bistable driven-dissipative systems near bifurcations can exhibit noise-activated switching between steady states. Here, we investigate how quantum vacuum fluctuations induce such…
Dosimetric characterization of a nanophotonic scintillator and applications to real-time in-vivo total body irradiation dosimetry
W. Jeffrey Zabel, Dixin Chen, Louis Martin-Monier +7
Purpose: Recent advances in metasurface photonics and manufacturing have enabled a nanophotonic surface coating to be applied to conventional scintillators, which has been shown to…
Continuum Neural Momentum Eigenstate for Variationally Solving Quasiparticles
David D. Dai, Marin SoljaÄiÄ
We design the first neural quantum state for continuum particles that, for any chosen allowed momentum , is by construction an exact eigenstate of total momentum with e…
Diffractive cascades for polychromatic hard X-ray focusing
William Michaels, Simo Pajovic, Joshua Chen +2
Diffractive focusing of hard X-rays has traditionally required structures with large aspect ratios due to the limited interaction of most materials with X-rays. This has increased…
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…
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…
