Optical Rotation—A Reliable Parameter for Authentication of Honey? [PDF]
Molecules, 2022 The controversial question of whether optical rotation data can be used to distinguish floral from honeydew honey was investigated. Specific optical rotation angles were determined for 41 honey samples, including floral, honeydew, and adulterated honey ...

Unconventional specular optical rotation in the charge ordered state of Kagome metal CsV3Sb5 [PDF]
Nature Communications, 2023 Kagome metals AV3Sb5 (A = K, Cs, Rb) provide a rich platform for intertwined orders, where evidence for time-reversal symmetry breaking, likely due to the long-sought loop currents, has emerged in STM and muon spin relaxation experiments.

Orbital Rotation of Trapped Particle in a Transversely Misaligned Dual-Fiber Optical Trap
IEEE Photonics Journal, 2016 We propose and demonstrate a novel optical orbital rotation technique for trapped particle in a transversely misaligned dual-fiber optical trap. The orbital rotation frequency can be controlled by varying the power of two counterpropagating beams.

Polarimetric Measurements of Surface Chirality Based on Linear and Nonlinear Light Scattering
Frontiers in Chemistry, 2021 A molecule, molecular aggregate, or protein that cannot be superimposed on its mirror image presents chirality. Most living systems are organized by chiral building blocks, such as amino acids, peptides, and carbohydrates, and any change in their ...

Rotating optical tweezers [PDF]
SPIE Proceedings, 2005 Several methods to rotate and align microscopic particles controllably have been developed. Control of the orientation of a trapped particle allows full three dimensional manipulation, whereas rotating particles are tools for the development of optically-driven micromachines. It has been shown that the orientation of an object in the laser trap depends
