Probing intermittent polariton vortex dynamics with two-point correlations
R. Cherbunin, A. Liubomirov, P. Kozhevin +5
Superconducting single-photon detectors with time resolution of 80 ps have been used to study the spatiotemporal dynamics of a trapped bosonic condensate of exciton-polaritons. Bot…

Semiconductor-Semimetal Transition in van der Waals Carbyne Crystals
Daniele Barettin, Stella V. Kavokina, Evgeny L. Ivchenko +1
Freestanding van der Waals crystals made of single-atom carbon chains (carbynes) have been recently realized technologically. Here we investigate their electronic and optical prope…

Quantum beats of a macroscopic polariton condensate in real space
R. V. Cherbunin, A. Liubomirov, D. Novokreschenov +2
We experimentally observe harmonic oscillations in a bosonic condensate of exciton-polaritons confined within an elliptical trap. These oscillations arise from quantum beats betwee…
