  • Broadband detection of 18 teeth in an 11-dB squeezing comb 
    Wilken, Dennis; Junker, Jonas; Heurs, Michèle (College Park, Md. [u.a.] : American Physical Society, 2024)
    Squeezed vacuum is a versatile resource of bipartite entanglement for quantum metrology and information. Optical parametric oscillators generate these states in a frequency comb structure. We show the simultaneous detection ...
  • Nonequilibrium mesoscopic conductance fluctuations as the origin of 1/f noise in epitaxial graphene 
    Kalmbach, C.-C.; Ahlers, Franz-J.; Schurr, J.; Müller, A.; Feilhauer, J.; Kruskopf, M.; Pierz, Klaus; Hohls, Frank; Haug, Rolf J. (College Park, MD : American Physical Society, 2016)
    We investigate the 1/f noise properties of epitaxial graphene devices at low temperatures as a function of temperature, current, and magnetic flux density. At low currents, an exponential decay of the 1/f noise power ...
  • Ultracold atom interferometry in space 
    Lachmann, Maike D.; Ahlers, Holger; Becker, Dennis; Dinkelaker, Aline N.; Grosse, Jens; Hellmig, Ortwin; Müntinga, Hauke; Schkolnik, Vladimir; Seidel, Stephan T.; Wendrich, Thijs; Wenzlawski, André; Carrick, Benjamin; Gaaloul, Naceur; Lüdtke, Daniel; Braxmaier, Claus; Ertmer, Wolfgang; Krutzik, Markus; Lämmerzahl, Claus; Peters, Achim; Schleich, Wolfgang P.; Sengstock, Klaus; Wicht, Andreas; Windpassinger, Patrick; Rasel, Ernst M. (London : Nature Publishing Group, 2021)
    Bose-Einstein condensates (BECs) in free fall constitute a promising source for space-borne interferometry. Indeed, BECs enjoy a slowly expanding wave function, display a large spatial coherence and can be engineered and ...
