Kibble-Zurek mechanism in polariton graphene
D. Solnyshkov, L. Bessonart, A. Nalitov +1
We study the formation of topological defects (quantum vortices) during the formation of a 2D polariton condensate at the point of a honeycomb lattice via the Kibble-Zurek mech…

Quantum metric and wavepackets at exceptional points in non-Hermitian systems
D. D. Solnyshkov, C. Leblanc, L. Bessonart +5
The usual concepts of topological physics, such as the Berry curvature, cannot be applied directly to non-Hermitian systems. We show that another object, the quantum metric, which…
