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…
Propagation and amplification dynamics of 1D polariton condensates
E. Wertz, A. Amo, D. D. Solnyshkov +9
The dynamics of propagating polariton condensates in one-dimensional microcavities is investigated through time resolved experiments. We find a strong increase in the condensate in…
Topological Wigner Crystal of Half-Solitons in a Spinor BEC
H. Terças, D. D. Solnyshkov, G. Malpuech
We consider a one-dimensional gas of half-solitons in a spinor Bose-Einstein condensate. We calculate the topological interaction potential between the half-solitons. Using a kinet…
ZnO-Based Polariton Laser Operating at Room Temperature: From Excitonic to Photonic Condensate
Feng Li, Laurent Orosz, Olfa Kamoun +13
A laser threshold is determined by the gain condition, which has been progressively reduced by the use of heterostructures and of quantum confinement. The polariton laser is the ul…
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…
Disorder Effects on Exciton-Polariton Condensates
G. Malpuech, D. Solnyshkov
The impact of a random disorder potential on the dynamical properties of Bose Einstein condensates is a very wide research field. In microcavities, these studies are even more cruc…
Separation and acceleration of analogues of magnetic monopoles in semiconductor microcavities
H. Flayac, D. Solnyshkov, G. Malpuech
Half-integer topological defects in polariton condensates can be regarded as magnetic charges, with respect to built-in effective magnetic fields present in microcavities. We show…
Pseudospin dynamics in multimode polaritonic Josephson junctions
G. Pavlovic, G. Malpuech, I. A. Shelykh
We analyzed multimode Josephson junctions with exciton-polaritons (polaritonic Josephson junctions) when several coupling mechanisms of fundamental and excited states are present.…
