Autor: Sanvitto, D., Pigeon, S., Amo, A., Ballarini, D., De Giorgi, M., Carusotto, I., Hivet, R., Pisanello, F., Sala, V. G., Soares-Guimaraes, P. S., Houdré, R., Giacobino, E., Ciuti, C., Bramati, A., Gigli, G.

While photons in vacuum are massless particles that do not interact with each other, significant photon-photon interactions appear in suitable nonlinear media, leading to novel hydrodynamic behaviors typical of quantum fluids. Here we show the format

Polariton superfluids reveal quantum hydrodynamic solitons

Autor: Amo, A., Pigeon, S., Sanvitto, D., Sala, V. G., Hivet, R., Carusotto, I., Pisanello, F., Lemenager, G., Houdre, R., Giacobino, E., Ciuti, C., Bramati, A.

A quantum fluid passing an obstacle behaves differently from a classical one. When the flow is slow enough, the quantum gas enters a superfluid regime and neither whirlpools nor waves form around the obstacle. For higher flow velocities, it has been

Spin rings in bi-stable planar semiconductor microcavities

Autor: Adrados, C., Amo, A., Liew, T. C. H., Hivet, R., Houdre, R., Giacobino, E., Kavokin, A. V., Bramati, A.

Publikováno v: Phys. Rev. Lett. 105, 216403 (2010)

A unique feature of exciton-polaritons, inherited from their mixed light-matter origin, is the strongly spin-dependent polariton-polariton interaction, which has been predicted to result in the formation of spin rings in real space [Shelykh et al., P

Light Engineering of the Polariton Landscape in Semiconductor Microcavities

Autor: Amo, A, Pigeon, S, Adrados, C, Houdre, R, Giacobino, E, Ciuti, C, Bramati, A

Publikováno v: Phys. Rev. B 82, 081301(R) (2010)

We demonstrate a method to create potential barriers with polarized light beams for polaritons in semiconductor microcavities. The form of the barriers is engineered via the real space shape of a focalised beam on the sample. Their height can be dete

Report

Observation of Superfluidity of Polaritons in Semiconductor Microcavities

Autor: Amo, A., Lefrere, J., Pigeon, S., Adrados, C., Ciuti, C., Carusotto, I., Houdre, R., Giacobino, E., Bramati, A.

Publikováno v: Nature Phys. 5, 805 (2009)

One of the most striking manifestations of quantum coherence in interacting boson systems is superfluidity. Exciton-polaritons in semiconductor microcavities are two-dimensional composite bosons predicted to behave as particular quantum fluids. We re
