Chirality-tunable vortex laser through intracavity scattering asymmetry [PDF]

APL Photonics
Laguerre–Gaussian (LG)-mode lasers offer compact sources that directly emit eigen-vortex beams with high transmission stability, making them attractive for modern integrated information technologies.

Chiral interactions, chiral states and “chiral neutrino oscillations”

Nuclear Physics B
In vacuum the ``chiral neutrino oscillations'', i.e. the periodic transitions between the left- and right-handed states do not occur. The produced state differs from the chiral component that appear in the Lagrangian of interactions and should be computed for each specific process. The phase difference between components of a produced neutrino is space-

Chiral Phonons in Chiral Materials

, 2021
The concept of chirality makes ubiquitous appearance in nature. Particularly, both a structure and its collective excitations may acquire well defined chiralities. In this work, we reveal an intrinsic connection between the chiralities of a crystal structure and its phonon excitations. We show that the phonon chirality and its propagation direction are

Epithelial cell chirality emerges through the dynamic concentric pattern of actomyosin cytoskeleton

eLife
The chirality of tissues and organs is essential for their proper function and development. Tissue-level chirality derives from the chirality of individual cells that comprise the tissue, and cellular chirality is considered to emerge through the ...

Crossover of skyrmion and helical modulations in noncentrosymmetric ferromagnets

New Journal of Physics, 2018
The coupling between angular (twisting) and longitudinal modulations arising near the ordering temperature of noncentrosymmetric ferromagnets strongly influences the structure of skyrmion states and their evolution in an applied magnetic field.

Tracking chirality in photoelectron circular dichroism

Physical Review Research
In photoelectron circular dichroism (PECD) it is generally difficult to trace how and when the chirality of the molecule is imprinted onto the photoelectron.

Quantitative Structure–Activity Relationship (QSAR) Modeling of Chiral CCR2 Antagonists with a Multidimensional Space of Novel Chirality Descriptors

Molecules
The development of chirality descriptors for quantitative chirality structure–activity relationship (QCSAR) modeling has always attracted attention, owing to the importance of chiral molecules in pharmaceutical, agriculture, food, and fragrance ...
