“…This setup was first proposed by Ruseckas et al in [28], to which we refer the reader for a detailed explanation of the system and only quote the resulting equation here. The system comprises of a waveguide system coupled to an ensemble of atoms, which could be realized either in a tapered fiber [47,48] or a hollow-core waveguide [49][50][51][52][53]. The atoms are characterized by the three hyperfine ground levels; one populated state |g and two unpopulated states |s1 and |s2 .…”

The Jackiw-Rebbi model describes a one-dimensional Dirac field coupled to a soliton field and can be equivalently thought of as a model describing a Dirac field with a spatially dependent mass term. Neglecting the dynamics of the soliton field, a kink in the background soliton profile yields a topologically protected zero-energy mode for the field, which in turn leads to charge fractionalisation. We show here that the model, in the first quantised form, can be realised in a driven slow-light setup, where photons mimic the Dirac field and the soliton field can be implemented–and tuned–by adjusting optical parameters such as the atom-photon detuning. Furthermore, we discuss how the existence of the zero-mode and its topological stability can be probed naturally by studying the transmission spectrum. We conclude by analysing the robustness of our approach against possible experimental errors in engineering the Jackiw-Rebbi Hamiltonian in this optical setup.

“…The resulting expression gives χ eff ∝ 1 / N . It clearly shows that there is an optimization to undertake regarding the number of molecules in the array: On one hand, there must be enough molecules to create sufficient optical depth to couple-in the polaritons [14]. On the other hand, in order to maximize the nonlinearity in Eq.…”

Single-photon nonlinearities using arrays of cold polar molecules

We model single photon nonlinearities resulting from the dipole-dipole interactions of cold polar molecules. We propose utilizing "dark state polaritons" to effectively couple photon and molecular states; through this framework, coherent control of the nonlinearity can be expressed and potentially used in an optical quantum computation architecture. Due to the dipole-dipole interaction the photons pick up a measurable nonlinear phase even in the single photon regime. A manifold of protected symmetric eigenstates is used as basis. Depending on the implementation, major sources of decoherence result from non-symmetric interactions and phonon dispersion. We discuss the strength of the nonlinearity per photon and the feasibility of this system.

“…AOS using an electromagnetically induced absorption grating (EIG) can be formed by a weak probe beam interacting with a strong standing wave coupled in a threelevel system [5]. More recently, AOS based on EIT has been realized in an atom-filled hollow fiber with light pulses containing only a few hundred photons [6,7]. All-optical phase control was also experimentally demonstrated as EIT-based cross-phase modulation [8].…”

Optical switching using controlled two-photon transition

New scheme of a real-time all-optical switching (AOS) was demonstrated as the fluorescence signal of cesium twophoton transition (TPT) with the control field. This work explored the optical phenomenon of the TPT with the control field that shares a common excited state, in which the TPT fluorescence is quenched under the control field intensity. The strong stimulated emission due to the control laser suppresses the TPT fluorescence, working as an optical switch. A "NOT gate" is generated for realization of AOS. The power spectrum of the intensity range, which can be used for the AOS, is determined.
