  • Parametric amplification of matter waves in dipolar spinor Bose-Einstein condensates 
    Deuretzbacher, Frank; Gebreyesus, Garu; Topic, Oliver; Scherer, Manuel; Lücke, Bernd; Ertmer, Wolfgang; Arlt, Jan J.; Klempt, Carsten; Santos, Luis (College Park, MD : American Physical Society, 2010)
    Spin-changing collisions may lead under proper conditions to the parametric amplification of matter waves in spinor Bose-Einstein condensates. Magnetic dipole-dipole interactions, although typically very weak in alkalimetal ...
  • Phase magnification by two-axis countertwisting for detection-noise robust interferometry 
    Anders, Fabian; Pezze, Luca; Smerzi, Augusto; Klempt, Carsten (College Park : American Physical Society, 2018)
    Entanglement-enhanced atom interferometry has the potential of surpassing the standard quantum limit and eventually reaching the ultimate Heisenberg bound. The experimental progress is, however, hindered by various technical ...
  • Quantum-Fluctuation-driven crossover from a dilute bose-einstein condensate to a macrodroplet in a dipolar quantum fluid 
    Chomaz, L.; Baier, S.; Petter, D.; Mark, M.J.; Wächtler, F.; Santos, Luis; Ferlaino, F. (College Park, MD : American Physical Society, 2016)
    In a joint experimental, theoretical effort, we report on the formation of a macrodroplet state in an ultracold bosonic gas of erbium atoms with strong dipolar interactions. By precise tuning of the s-wave scattering length ...
  • Second-order correlation function of a phase fluctuating Bose-Einstein condensate 
    Cacciapuoti, L.; Hellweg, D.; Kottke, M.; Schulte, T.; Ertmer, Wolfgang; Arlt, Jan J.; Sengstock, K.; Santos, Luis; Lewenstein, M. (American Physical Society, 2003)
    The coherence properties of phase fluctuating Bose-Einstein condensates are studied both theoretically and experimentally. We derive a general expression for the N-particle correlation function of a condensed Bose gas in ...
  • Spin dynamics in a two-dimensional quantum gas 
    Pedersen, Poul L.; Gajdacz, Miroslav; Deuretzbacher, Frank; Santos, Luis; Klempt, Carsten; Sherson, Jacob F.; Hilliard, Andrew J.; Arlt, Jan J. (College Park : American Physical Society, 2014)
    We have investigated spin dynamics in a two-dimensional quantum gas. Through spin-changing collisions, two clouds with opposite spin orientations are spontaneously created in a Bose-Einstein condensate. After ballistic ...
  • Spontaneous symmetry breaking in spinor Bose-Einstein condensates 
    Scherer, Manuel; Lücke, Bernd; Peise, Jan; Topic, Oliver; Gebreyesus, Garu; Deuretzbacher, Frank; Ertmer, Wolfgang; Santos, Luis; Klempt, Carsten; Arlt, Jan J. (College Park, MD : American Physical Society, 2013)
    We present an analytical model for the theoretical analysis of spin dynamics and spontaneous symmetry breaking in a spinor Bose-Einstein condensate (BEC). This allows for an excellent intuitive understanding of the processes ...
  • The sounds of science - A symphony for many instruments and voices 
    Alexander, Gerianne; Allen, Roland E.; Atala, Anthony; Bowen, Warwick P.; Coley, Alan A.; Goodenough, John B.; Katsnelson, Mikhail I.; Koonin, Eugene V.; Krenn, Mario; Madsen, Lars S.; Månsson, Martin; Mauranyapin, Nicolas P.; Melvin, Art I.; Rasel, Ernst; Reichl, Linda E.; Yampolskiy, Roman; Yasskin, Philip B.; Zeilinger, Anton; Lidström, Suzy (Bristol : Institute of Physics Publishing, 2020)
    Sounds of Science is the first movement of a symphony for many (scientific) instruments and voices, united in celebration of the frontiers of science and intended for a general audience. John Goodenough, the maestro who ...
  • The space atom laser: An isotropic source for ultra-cold atoms in microgravity 
    Meister, Matthias; Roura, Albert; Rasel, Ernst M.; Schleich, Wolfgang P. (Bristol : Institute of Physics Publishing, 2019)
    Atom laser experiments with Bose-Einstein condensates (BECs) performed in ground-based laboratories feature a coherent and directed beam of atoms which is accelerated by gravity. In microgravity the situation is fundamentally ...
  • Time-domain optics for atomic quantum matter 
    Kanthak, Simon; Gebbe, Martina; Gersemann, Matthias; Abend, Sven; Rasel, Ernst M.; Krutzik, Markus ([Bad Honnef] : Dt. Physikalische Ges., 2021)
    We investigate time-domain optics for atomic quantum matter. Within a matter-wave analog of the thin-lens formalism, we study optical lenses of different shapes and refractive powers to precisely control the dispersion of ...
  • Tunable dual-species Bose-Einstein condensates of 39K and 87Rb 
    Wacker, L.; Jørgensen, N.B.; Birkmose, D.; Horchani, R.; Ertmer, Wolfgang; Klempt, Carsten; Winter, N.; Sherson, J.; Arlt, Jan J. (College Park : American Physical Society, 2015)
    We present the production of dual-species Bose-Einstein condensates (BECs) of 39K and 87Rb. Preparation of both species in the |F=1,mF=−1⟩ state enabled us to exploit a total of three Feshbach resonances, which allows for ...
  • Waveguide for Bose-Einstein condensates 
    Bongs, Kai; Burger, S.; Dettmer, S.; Hellweg, D.; Arlt, Jan J.; Ertmer, Wolfgang; Sengstock, K. (American Physical Society, 2001)
    We report on the creation of Bose-Einstein condensates of 87Rb in a specially designed hybrid, optical dipole and magnetic trap. This trap naturally allows the coherent transfer of matter waves into a pure optical dipole ...
