Photon statistics analysis of h-BN quantum emitters with pulsed and continuous-wave excitation

Kavli Affiliate: Harry Atwater | Summary:We report on the quantum photon statistics of hexagonal boron nitride (h-BN) quantum emitters by analyzing the Mandel Q parameter. We have measured the Mandel Q parameter for h-BN quantum emitters under various temperatures and pump power excitation conditions. Under pulsed excitation we can achieve a Mandel Q of -0.002 […]

Spacetime symmetries and geometric diffusion

Kavli Affiliate: J. S. Villasenor | Summary:We examine relativistic diffusion through the frame and observer bundles associated with a Lorentzian manifold $(M,g)$. Our focus is on spacetimes with a non-trivial isometry group, and we detail the conditions required to find symmetric solutions of the relativistic diffusion equation. Additionally, we analyze the conservation laws associated with […]

Iterated Monodromy Group With Non-Martingale Fixed-Point Process

Kavli Affiliate: Zheng Zhu | First 5 Authors: Jianfei He, Zheng Zhu, , , | Summary: We construct families of rational functions $f: mathbb{P}^1_k rightarrow mathbb{P}^1_k$ of degree $d geq 2$ over a perfect field $k$ with non-martingale fixed-point processes. Then for any normal variety $X$ over $mathbb{P}_{bar{k}}^N$, we give conditions on $f: X rightarrow […]

Neural Downscaling for Complex Systems: from Large-scale to Small-scale by Neural Operator

Kavli Affiliate: Jing Wang | First 5 Authors: Pengyu Lai, Jing Wang, Rui Wang, Dewu Yang, Haoqi Fei | Summary: Predicting and understanding the chaotic dynamics in complex systems is essential in various applications. However, conventional approaches, whether full-scale simulations or small-scale omissions, fail to offer a comprehensive solution. This instigates exploration into whether modeling […]
