Chirality-induced orbital-angular-momentum selectivity (CIOAMS) enables distinguishing electron orbital angular momentum (OAM) in chiral materials. This discovery could advance quantum technologies by controlling electron behavior.
Area of Science:
- Quantum mechanics
- Condensed matter physics
- Materials science
Background:
- Chirality-induced spin selectivity (CISS) is a phenomenon where electron spin is selected when passing through chiral materials.
- The role of electron orbital angular momentum (OAM) in CISS is not fully understood.
Purpose of the Study:
- To investigate chirality-induced orbital-angular-momentum selectivity (CIOAMS) in electron transmission and scattering.
- To explore the potential of CIOAMS in quantum technologies.
Main Methods:
- Time-dependent Schrödinger equation for electronic wavepacket propagation.
- Simulating electron scattering from a corrugated surface.
- Mott polarimetry measurements.
Main Results:
- Demonstrated polarization of electron OAM in chiral media.
- Achieved spatial resolution of wavepackets with opposite OAM after scattering.
- Established a link between OAM and CISS mechanisms.
Conclusions:
- OAM plays a significant role in CISS.
- CIOAMS can be exploited for novel quantum technologies.

Chirality
Chiral objects exhibit a sense of handedness when they interact with another chiral object. For example, our left foot can only fit in the left shoe and not in the right shoe. Achiral objects — objects that have...

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
