Excerpt:
Using all-optical methods, scientists from Skoltech and the University of Southampton, U.K., have created an artificial lattice called Lieb lattice. All nodes in the lattice hold polaritons- quasiparticles that are half-light and half-matter excitations in semiconductors.
Thi laser-generated polariton lattice allowed scientists to demonstrate breakthrough results significant for condensed matter physics. It can be used to design next-generation devices like optical computers reliant on dispersion management and guiding light.
Under the right conditions, polaritons form coherent many-body states of matter like Bose-Einstein condensates. This gives access to exotic dissipative nonlinear dynamics.
