    • Effects of Fermion Exchange on the Polarization of Exciton Condensates 

      Combescot, Monique; Combescot, Roland; Alloing, Mathieu; Dubin, François (APS Physics, 2015-03-04)
      Article
      Open Access
      Exchange interaction is responsible for the stability of elementary boson condensates with respect to momentum fragmentation. This remains true for composite bosons when single fermion exchanges are included but spin ...
    • High Quality Factor Mechanical Resonators Based on WSe2 Monolayers 

      Morell, Nicolas; Reserbat-Plantey, Antoine; Tsioutsios, Ioannis; Schädler, Kevin Gerd; Dubin, François; Koppens, Frank H. L.; Bachtold, Adrian (ACS, 2016-07-26)
      Article
      Open Access
      Suspended monolayer transition metal dichalcogenides (TMD) are membranes that combine ultralow mass and exceptional optical properties, making them intriguing materials for opto-mechanical applications. However, the low ...
    • Long-lived spin coherence of indirect excitons in GaAs coupled quantum wells 

      Beian, Mussie; Alloing, Mathieu; Cambril, Edmond; Gomez Carbonell, Carmen; Osmond, Johann; Lemaître, Aristide; Dubin, François (IOP, 2015-04-30)
      Article
      Open Access
      We study spatially indirect excitons confined in a symmetric GaAs double quantum well. We show that the spin polarisation of very dilute gases can be optically imprinted, in both pure and superposition states. In the regime ...
