Interaction-free, single-pixel quantum imaging with undetected photons

open access: yesnpj 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

open access: yesnpj 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.

Motional consensus of self-propelled particles

open access: yesScientific Reports, 2023
The motional consensus of self-propelled particles is studied in both noise-free cases and cases with noise by the standard Vicsek model. In the absence of noise, we propose a simple method, using grid-based technique and defining the normalized variance

Disordered metasurface enabled single-shot full-Stokes polarization imaging leveraging weak dichroism

open access: yesNature Communications, 2023
Polarization, one of the fundamental properties of light, is critical for certain imaging applications because it captures information from the scene that cannot directly be recorded by traditional intensity cameras.
