“…Here we have demonstrated spin-selective photonic excitation transport where the internal emitter degrees of freedom are coupled to an underlying chiral geometry. This phenomenon has a complete description within the electric dipole approximation, placing it within the new class of nonmagnetic chiral interactions exhibiting very strong optical responses [37,38]. Precise control over the transport and superradiant or subradiant emission of photons is a fundamental goal of quantum information science and could contribute to the development of new quantum technologies.…”

Chirality, or handedness, is a geometrical property denoting a lack of mirror symmetry. Chiral systems are ubiquitous in nature and are associated with the non-reciprocal interactions observed in topological materials and complex biomolecules, among other phenomena. In this paper, we demonstrate that chiral arrangements of dipole-coupled quantum emitters can facilitate the unidirectional transport of photonic spin excitations without breaking time-reversal symmetry. We show that this spin-selective transport stems from a universal emergent spin-orbit coupling induced by the chiral geometry, which in turn, results in a nontrivial topology. We also examine the effects of collective dissipation on the dynamics and find that many-body coherences lead to helicity-dependent photon emission: an effect we call helical superradiance. Applications to emerging quantum technologies as well as the potential role of spin-selective photon transport in nature are discussed.

Also, we discuss the future directions of non-classical light engineering using strong laser fields, and the potential applications in ultrafast and quantum information science. 4 6 Conclusions 43

Drawing inspiration from a remarkable chiral force found in nature, we show that a static electric field combined with an optical lin ⊥ lin polarization standing wave can exert a chiral optical force on a small chiral molecule that is several orders of magnitude stronger than other chiral optical forces proposed to date, being based on leading electric-dipole interactions rather than relying on weak magnetic-dipole and electric-quadrupole interactions. Our chiral optical force applies to most small chiral molecules, including isotopically chiral molecules, and does not require a specific energy-level structure. Potential applications range from chiral molecular matter-wave interferometry for precision metrology and tests of fundamental physics to the resolution of enantiomers for use in chemistry and biology.
