• Title: Controllable fusion of electromagnetic bosons in two-dimensional semiconductors
• Authors: Sergue\"i V. Andreev
• Abstract summary: We propose a physical principle for controllable interactions of identical electromagnetic bosons (excitons or polaritons) in 2D semiconductors. Key ingredients are tightly bound biexcitons and in-plane anisotropy of the host structure due to, e.g., a uniaxial strain. We show that anisotropy-induced splitting of the radiative exciton doublet couples the biexciton state to continua of boson scattering states.

• Abstract: We propose a physical principle for implementation of controllable interactions of identical electromagnetic bosons (excitons or polaritons) in two-dimensional (2D) semiconductors. The key ingredients are tightly bound biexcitons and in-plane anisotropy of the host structure due to, e.g., a uniaxial strain. We show that anisotropy-induced splitting of the radiative exciton doublet couples the biexciton state to continua of boson scattering states. As a result, two-body elastic scattering of bosons may be resonantly amplified when energetically tuned close to the biexciton by applying a transverse magnetic field or tuning the coupling with the microcavity photon mode. At the resonance, bosonic fields undergo quantum reaction of fusion accompanied by their squeezing. For excitons, we predict giant molecules (Feshbach dimers) which can be obtained from a biexciton via rapid adiabatic sweeping of the magnetic field across the resonance. The molecules possess non-trivial entanglement properties. Our proposal holds promise for the strongly-correlated photonics and quantum chemistry of light.

We measure the decay rate and the quasiparticle residue of the driven polaron from the Rabi oscillations between the two internal states.

  Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement. We show that this mechanism is merely one among a complex family of phenomena that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance.

Using time-dependent theory, we investigate the spectrum of the radiation emitted by the two-atom system. We show that it is modulated in time, and that the presence of the oscillating mirror can enhance or inhibit the decay rate.
