This groundbreaking study unveils that chirality in carbon nanotubes persists in charged excitons, influencing quantum states significantly.

Applying strain to achiral solids containing subunits of opposite chirality can induce controllable handedness.

Adding an electron or hole to excitons in carbon nanotubes preserves their optical chirality, opening possibilities for electrically controlled light amplification, detection, and modulation.

Mirror bacteria are hypothetical synthetic organisms built from molecules of opposite chirality to those used throughout nature. This primer discusses their potential dangers: because of their chiral ...

The CISS effect dictates a profound relationship between a molecule's physical 3D shape (its chirality) and the quantum spin of electrons moving through it. When an electron attempts to travel through a chiral molecule, the molecule acts as an aggressive quantum filter. Depending on the molecule's handedness, it will only permit electrons of a specific spin state (spin-up or spin-down) to pass efficiently.

Scientists from Tokyo Metropolitan University have discovered that charged states made of two electrons and a positively charged hole (or vice versa) on atomically thin rolls of carbon atoms have a st...

When two STOV pulses, E1 and E2, carrying charges ℓ1 and ℓ2, collide in both space and time, their superposition Etotal = E1 + E2 can exhibit new phase singularities SV1 that go beyond those found in a single beam. Secondary vortices arise at points where the total field amplitude vanishes, and the phase becomes undefined. Geometrically, these singularities correspond to the intersection of the real and imaginary components of the field on sign-changing surfaces (see in Supplementary S1). In other words, if the real part of Etotal changes sign on one surface, and the imaginary part similarly changes sign on another, their intersection forms a trajectory of zero intensity and undefined phase—a topological singularity. This phenomenon is analogous to phenomena in classical and quantum mechanics, as illustrated in Fig. 1a, b. The collision of two vortices effectively creates a network of sign-changing nodes within the three-dimensional spatiotemporal volume. Crucially, the number of secondary vortices is set by the difference in input charges, N = ∣ℓ2 − ℓ1∣, with each core carrying a unit topological charge. For example, when STOV pulses with ℓ1 = +3 and ℓ2 = −3 collide, N = 6 secondary vortices are generated (see Fig. 1c)...
