Uniqueness of phase retrieval from offset linear canonical transform
The classical phase retrieval refers to the recovery of an unknown signal from its Fourier magnitudes, which is widely used in fields such as quantum mechanics, signal processing, optics, etc. The offset linear canonical transform (OLCT), which is a more general type of linear integral transform including Fourier transform (FT), fractional Fourier transform (FrFT), and linear canonical transform (LCT) as its special cases. Hence, in this paper, we focus on the uniqueness problem of phase retrie…

Tensor meson transition form factors in holographic QCD and the muon $g-2$
Despite the prominence of tensor mesons in photon-photon collisions, until recently their contribution to the hadronic light-by-light (HLbL) scattering part of the anomalous magnetic moment of the muon has been estimated to be at the level of only a few $10^{-12}$. A recent reanalysis within the dispersive approach has found that after resolving the issue of kinematic singularities in previous approaches, a larger result is obtained, a few $10^{-11}$, and with opposite sign as in previous resul…

Study Reveals Vast Aztec Trade Networks Behind Mexico's Pre-Colombian Obsidian Hoards
Archaeologists found that while the Mexica primarily used green obsidian, obsidian also came from at least seven other locations.

Strong coupling of chiral light with chiral matter: a macroscopic study
Maximizing the interaction between chiral light and chiral matter is pivotal for the advancement of technologies enabling optical detection that distinguishes between different handedness in chiral organic molecules. One strategy involves developing a resonator that sustains photonic modes with non-zero electromagnetic handedness, which interact differently with chiral molecules of opposite enantiomers. When chiral molecules are positioned in resonator hotspots, they can alter the system's char…

Cavity ringdown spectroscopy at 2 $μ$m wavelength assisted by a comb-locked optical parametric oscillator
We report on a comb-locked cavity ring-down spectrometer developed for high-precision molecular spectroscopy at 2 $μ$m. It is based on the use of an external-cavity diode laser that is offset-frequency locked to the signal output of a singly-resonant optical parametric oscillator. This latter acts as reference laser, being locked to a self-referenced optical frequency comb, which in turn is stabilized against a GPS-disciplined Rb-clock. The performance of the spectrometer is investigated by pr…

Machine learning assisted speckle and OAM spectrum analysis for enhanced turbulence characterisation
Atmospheric turbulence presents a major obstacle to the performance of free-space optical (FSO) communication and environmental sensing. While most studies focused on robust detection and recognition of transmitted structured light in turbulent media, a critical, yet often underexplored, avenue involves leveraging the structure of light itself to detect and characterize the medium itself. Here we introduce a deep learning framework that synergistically leverages post-transmission intensity spec…
