Noise-tolerant LiDAR approaching the standard quantum-limited precision

open access: yesLight: Science & Applications
Quantum-inspired imaging techniques have been proven to be effective for LiDAR with the advances of single photon detectors and computational algorithms. However, due to the disturbance of background noise and the varies of signal in outdoor environment,

Nanostructured superconductors

open access: yes
The relevant length scales for superconductivity are of the order of nanometers. By confining the superconducting condensate to such dimensions, many physical properties change substantially, and novel phenomena emerge, which are absent in the pristine material.

Proximity effect in ferromagnet-superconductor hybrid structures: role of the pairing symmetry

open access: yes, 2002
The spatial variations of the pair amplitude, and the local density of states in d-wave or s-wave superconductor-ferromagnet hybrid structures are calculated self consistently using the Bogoliubov-deGennes formalism within the two dimensional extended ...

Magnetization reversal of ferromagnetic nanodisc placed above a superconductor

open access: yes, 2004
Using numerical simulation we have studied a magnetization distribution and a process of magnetization reversal in nanoscale magnets placed above a superconductor plane. In order to consider an influence of superconductor on magnetization distribution in

Photoswitchable exceptional points derived from bound states in the continuum

open access: yesLight: Science & Applications
Bound states in the continuum (BICs) and exceptional points (EPs), as two distinct physical singularities represented by complex frequencies in non-Hermitian systems, have garnered significant attention and clear definitions in their respective fields in
