Bio: After graduation from the Moscow State University, Dr. S. S. Gavrilov works in the Institute of Solid State Physics, Chernogolovka. His research interests lie in the field of nonlinear science and its applications to macroscopically coherent states in solid state physics and optics.
Abstract: Based on the Gross-Pitaevskii equations, the system of cavity polaritons driven by a plane electromagnetic wave is found to undergo the spontaneous breaking of spatial symmetry, which results in a lifted phase locking with respect to the driving field and, consequently, in the possibility of internal ordering. In particular, periodic spin and intensity patterns arise in polariton wires; they exhibit strong long-range order and can serve as media for signal transmission. Such patterns have the properties of “chimera states” typical of oscillator networks: they are formed spontaneously in perfectly homogeneous media and can be partially chaotic.
