  • 40K-87Rb Feshbach resonances: Modeling the interatomic potential 
    Klempt, Carsten; Henninger, T.; Topic, O.; Will, J.; Ertmer, Wolfgang; Tiemann, E.; Arlt, Jan J. (College Park : American Physical Society, 2007)
    We have observed 28 heteronuclear Feshbach resonances in ten spin combinations of the hyperfine ground states of a 40K−87Rb mixture. The measurements were performed by observing the loss rates from an atomic mixture at ...
  • Giant anisotropy of zeeman splitting of quantum confined acceptors in Si/Ge 
    Haendel, K.-M.; Winkler, R.; Denker, U.; Schmidt, O.G.; Haug, Rolf J. (College Park, MD : American Physical Society, 2006)
    Shallow acceptor levels in Si/Ge/Si quantum well heterostructures are characterized by resonant-tunneling spectroscopy in the presence of high magnetic fields. In a perpendicular magnetic field we observe a linear Zeeman ...
  • High-order harmonic generation in the presence of a resonance 
    Tudorovskaya, Maria; Lein, Manfred (College Park, MD : American Physical Society, 2011)
    We investigate high-order harmonic generation from laser-irradiated systems that support a shape resonance. From the numerical solution of the time-dependent Schrödinger equation, we calculate the harmonic spectra and the ...
  • Mode-cleaning and injection optics of the gravitational-wave detector GEO600 
    Goßler, S.; Casey, M.M.; Freise, A.; Grant, A.; Grote, H.; Heinzel, G.; Heurs, Michèle; Husman, M.E.; Kötter, K.; Leonhardt, V.; Lück, Harald; Malec, M.; Mossavi, K.; Nagano, S.; McNamara, P.W.; Plissi, M.V.; Quetschke, V.; Robertson, D.I.; Robertson, N.A.; Rüdiger, A.; Schilling, R.; Skeldon, K.D.; Strain, K.A.; Torrie, C.I.; Ward, H.; Weiland, U.; Willke, B.; Winkler, W.; Hough, J.; Danzmann, K. (College Park, MD : American Institute of Physics (AIP), 2003)
    A study to investigate the mode-cleaning and injection optics of the gravitational-wave detector GEO600 was presented. The instrument uses two high-finesse triangular ring cavities of 8 m optical wavelength each, as an ...
  • Rapid generation of all-optical K 39 Bose-Einstein condensates using a low-field Feshbach resonance 
    Herbst, A.; Albers, H.; Stolzenberg, K.; Bode, S.; Schlippert, D. (Woodbury, NY : Inst., 2022)
    Ultracold potassium is an interesting candidate for quantum technology applications and fundamental research as it allows controlling intra-atomic interactions via low-field magnetic Feshbach resonances. However, the ...
  • Resonant optical excitation of longitudinal-optical phonons and intermixing in InAsAlAs single quantum dots 
    Sarkar, D.; Van Der Meulen, H.P.; Calleja, J.M.; Meyer, J.M.; Haug, Rolf J.; Pierz, Klaus (College Park, MD : American Institute of Physics, 2008)
    Excitations of a single InAsAlAs self-assembled quantum dot were investigated by photoluminescence excitation spectroscopy. Resonant absorption by longitudinal-optical (LO) phonons of the quantum dot and the barriers is ...
  • Time-domain high-finesse atom interferometry 
    Hinderthür, H.; Ruschewitz, F.; Lohe, H.-J.; Lechte, S.; Sengstock, K.; Ertmer, Wolfgang (American Physical Society, 1999)
    We report on experiments of multiple-beam atom interferometry in the time domain. Laser-cooled and trapped atoms interact with atomic "multiple beam splitters" realized by time sequences of resonant laser pulses. The output ...
  • 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 ...
