Skyrmion Formation and Optical Spin-Hall Effect in an Expanding Coherent Cloud of Indirect Excitons
D. V. Vishnevsky, H. Flayac, A. V. Nalitov +3
We provide a theoretical description of the polarization pattern and phase singularities experimentally evidenced recently in a condensate of indirect excitons [H. High et al., Nat…
Macroscopic quantum self-trapping and Josephson oscillations of exciton-polaritons
M. Abbarchi, A. Amo, V. G. Sala +8
A textbook example of quantum mechanical effects is the coupling of two states through a tunnel barrier. In the case of macroscopic quantum states subject to interactions, the tunn…
Landau versus Spin Superfluidity in Spinor Bose-Einstein Condensates
H. Flayac, H. Tercas, D. D. Solnyshkov +1
We consider a spin-1/2 Bose-Einstein condensate prepared initially in a single spin projection. The two channels of excitations existing in such a system (namely density and spin w…
Parametric Inversion of Spin Currents in Semiconductor Microcavities
H. Flayac, D. D. Solnyshkov, G. Malpuech +1
The optical spin-Hall effect results in the formation of an antisymmetric real space polarization pattern forming spin currents. In this paper, we show that the exciton-polariton p…
Transmutation from Skyrmions to Half-Solitons Driven by the Nonlinear Optical Spin-Hall Effect
H. Flayac, D. D. Solnyshkov, I. A. Shelykh +1
We show that the polarization domains generated in the linear optical spin-Hall effect by the analog of spin-orbit interaction for exciton-polaritons are associated with the format…
Half-solitons in a polariton quantum fluid behave like magnetic monopoles
R. Hivet, H. Flayac, D. D. Solnyshkov +8
Monopoles are magnetic charges, point-like sources of magnetic field. Contrary to electric charges they are absent in Maxwell's equations and have never been observed as fundamenta…
