  • Fabrication of quantum point contacts by engraving GaAs/AlGaAs heterostructures with a diamond tip 
    Regul, J.; Keyser, U.F.; Paesler, M.; Hohls, Frank; Zeitler, U.; Haug, Rolf J.; Malavé, A.; Oesterschulze, E.; Reuter, D.; Wieck, A.D. (College Park, MD : American Institute of Physics, 2002)
    We use the all-diamond tip of an atomic force microscope for the direct engraving of high-quality quantum point contacts in GaAs/AlGaAs heterostructures. The processing time is shortened by two orders of magnitude compared ...
  • Self-bound crystals of antiparallel dipolar mixtures 
    Arazo, Maria; Gallemí, Albert; Guilleumas, Montserrat; Mayol, Ricardo; Santos, Luis (College Park, MD : APS, 2023)
    Recent experiments have created supersolids of dipolar quantum droplets. The resulting crystals lack, however, a genuine cohesive energy and are maintained by the presence of an external confinement, bearing a resemblance ...
