Dual-Output Mode Analysis of Multimode Laguerre-Gaussian Beams via Deep Learning
Optics, 2021 The Laguerre-Gaussian (LG) beam demonstrates great potential for optical communication due to its orthogonality between different eigenstates, and has gained increased research interest in recent years. Here, we propose a dual-output mode analysis method

Higher-order quantum spin Hall effect in a photonic crystal
Nature Communications, 2020 The quantum spin Hall effect is limited to one-dimensional lower boundary states which limits the possibilities for its exploitation in photonic devices.

High-performance complementary resistive switching in ferroelectric film
AIP Advances, 2021 The complementary resistive switch (CRS) offers a promising logic-in-memory functionality and is a potential solution to the “von Neumann bottleneck” problem, but the CRS structure composed of two anti-serially connected bipolar resistive switching cells

Neural network-based prediction of the secret-key rate of quantum key distribution
Scientific Reports, 2022 Numerical methods are widely used to calculate the secure key rate of many quantum key distribution protocols in practice, but they consume many computing resources and are too time-consuming.

Digital fingerprinting of microstructures
Computational Materials Science, 2023 Finding efficient means of fingerprinting microstructural information is a critical step towards harnessing data-centric machine learning approaches. A statistical framework is systematically developed for compressed characterisation of a population of images, which includes some classical computer vision methods as special cases.

Dielectric relaxation of interfacial polarizable molecules in chitosan ice-hydrogel materials
Journal of Materiomics, 2018 The functionalities of hydrogel-based smart materials are highly related to the electrostatic interactions and molecular polarization associated with the polymer networks and encapsulated water droplets, and therefore the dielectric responses of the ...

Multiphoton non-local quantum interference controlled by an undetected photon
Nature Communications, 2023 Usually, observation of quantum interference in a non-local scenario (that is, when Alice’s measurement settings and Bob’s outcomes are space-like separated) relies on entanglement.

A ReMeDI for Microstructure Noise [PDF]
SSRN Electronic Journal, 2019 We introduce the Realized moMents of Disjoint Increments (ReMeDI) paradigm to measure microstructure noise (the deviation of the observed asset prices from the fundamental values caused by market imperfections). We propose consistent estimators of arbitrary moments of the microstructure noise process based on high‐frequency data, where the noise ...

Interaction-free, single-pixel quantum imaging with undetected photons
npj Quantum Information, 2023 A typical imaging scenario requires three basic ingredients: (1) a light source that emits light, which in turn interacts and scatters off the object of interest; (2) detection of the light being scattered from the object and (3) a detector with spatial ...

Low-energy gap emerging from confined nematic states in extremely underdoped cuprate superconductors
npj Quantum Materials, 2023 The pairing mechanism of high-temperature superconductivity in cuprates is regarded as one of the most challenging issues in condensed matter physics. The core issue concerns how the Cooper pairs are formed.
