WebChirality is defined by the lack of certain features of symmetry, which lead to an object not being superimposable on its mirror image. Handedness is a different phenomenon relating to the ability to classify chiral objects into right-handed and left-handed objects. Test your knowledge on Chirality! WebOptical chirality is a fundamental and tunable property of light. Our demenstration of superchiral light raises exciting possibilities to sculpt the three-dimensional shape of the electromagnetic field, to bring other dark transitions to light. Documentation:
