Time Crystals in Coupled Exciton-Polariton Condensates
Xuan Ye, Hong-Jin Xiong, Alexey Kavokin +1
In this paper, we show that time crystals can emerge in coupled exciton-polariton condensates without periodic external driving, enabled instead by incoherent gain and dissipation…

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…
