Electron-phonon interactions in double layer graphene superfluids
… transition from Fermi liquid to Bose-Einstein condensate of excitons in double layer graphene has potential for use in ultra-low power device applications. These devices operate based on coherent interlayer transport and could far outperform traditional CMOS devices both in switching speed and …

Collective modes in strongly correlated electron systems measured with momentum-resolved electron energy-loss spectroscopy
… which has been proposed to contain a Bose condensate of excitons. Using M-EELS, we demonstrate the existence of an exciton condensate in TiSe2. Its experimental signature is a soft electronic collective mode that disperses to zero energy near the charge density wave (CDW) transition …
