Journal ArticleDOI
Collective fluid dynamics of a polariton condensate in a semiconductor microcavity
Alberto Amo,Daniele Sanvitto,Fabrice P. Laussy,Dario Ballarini,E. del Valle,M. D. Martín,Aristide Lemaître,Jacqueline Bloch,D. N. Krizhanovskii,M. S. Skolnick,Carlos Tejedor,Luis Viña +11 more
TL;DR: Using a coherent excitation triggered by a short optical pulse, a macroscopically degenerate state of polaritons are created that can be made to collide with a variety of defects present in the microcavity and opens the way to the investigation of new phenomenology of out-of-equilibrium condensates.
Journal ArticleDOI
All-optical polariton transistor
Dario Ballarini,M. De Giorgi,Emiliano Cancellieri,Emiliano Cancellieri,Romuald Houdré,Elisabeth Giacobino,Roberto Cingolani,Alberto Bramati,Giuseppe Gigli,Giuseppe Gigli,Daniele Sanvitto +10 more
TL;DR: This work demonstrates a scheme of all-optical transistor based on exciton polaritons in semiconductor microcavities, which exhibits full connectivity in the same chip plane.
Journal ArticleDOI
Room-temperature superfluidity in a polariton condensate

TL;DR: In this paper, a transition from supersonic to superfluid flow in a polariton condensate under ambient conditions was demonstrated by using an organic microcavity supporting stable Frenkel exciton-polaritons at room temperature.
Journal ArticleDOI
Exploring Light–Matter Interaction Phenomena under Ultrastrong Coupling Regime

TL;DR: In this paper, the authors reported a Rabi energy splitting (2ℏΩR) of 1.12 eV and record values of the coupling ratio up to 0.6-fold the material band gap in organic semiconductor microcavities and up to 1.5-fold in monolithic heterostructure organic light-emitting diodes working at room temperature.

TL;DR: In the key to Fig. 2a of this Article, the units for the control intensity were inadvertently given as mW instead of μW, and the correct version of Fig.2 appears below.
