Chiral condensates in a polariton hexagonal ring
We model vortex modes in semiconductor micropillars. TE-TM splitting creates unique vortex states, selectively excitable by lasers, leading to bistability at high intensities.
Area of Science:
- Quantum optics
- Condensed matter physics
- Semiconductor physics
Background:
- Exciton-polariton condensates exhibit complex vortex states.
- Semiconductor micropillars support specific optical modes.
- TE-TM splitting influences polarization degeneracy.
Purpose of the Study:
- Model vortex mode generation in hexagonal ring micropillars.
- Investigate the impact of TE-TM splitting on vortex states.
- Explore selective excitation and interaction of vortex modes.
Main Methods:
- Theoretical modeling of vortex mode generation.
- Analysis of bifurcation diagrams for vortex states.
- Simulation of selective excitation using coherent pump beams.
Main Results:
- TE-TM splitting lifts degeneracy, creating non-degenerate vortex states.
- Vortex states with different topological charges and polarizations emerge.
- Selective excitation of specific vortex modes is demonstrated.
- Polariton-polariton interactions induce coupling and bistability at high intensities.
Conclusions:
- TE-TM splitting offers control over vortex mode generation.
- Tunable excitation enables selective manipulation of quantum states.
- Bistability in polariton condensates can be achieved and controlled.

The chair form is the most stable and derives its name from its resemblance to the “easy chair.” In the chair conformation, two carbon atoms are arranged out-of-plane — one above and one below, minimizing the torsional strain. In the chair form, the bond angle is very close to the ideal...
