  • Charge-spin excitations of the Ising-type fractional quantum Hall ferromagnets 
    Výborný, Karel; Dethlefsen, Annelene F.; Haug, Rolf J.; Wójs, Arkadiusz (College Park, MD : American Physical Society, 2009)
    We study the low-lying excitations from the fractional quantum Hall states at filling factors 2/3 and 2/5 and argue that the charge-carrying excitations involve spin flips, and, in particular, possibly more than one. ...
  • Core-shell particles as efficient broadband absorbers in infrared optical range 
    Evlyukhin, Andrey B.; Nerkararyan, Khachatur V.; Bozhevolnyi, Sergey I. (Washington, DC : OSA - The Optical Society, 2019)
    We demonstrate that efficient broadband absorption of infrared radiation can be obtained with deeply subwavelength spherical dielectric particles covered by a thin metal layer. Considerations based on Mie theory and the ...
  • Depinning transitions between adsorbate chains coupled by Friedel oscillations 
    Godzik, G.; Block, T.; Pfnür, Herbert (College Park, MD : American Physical Society, 2003)
    The low coverage phase transitions of the p(8×1) and the p(5×1) chain structures of the Sr/Mo(112) system have been investigated with low-energy electron diffraction (LEED) at constant coverages. It turns out that both ...
  • Height analysis of amorphous and crystalline ice structures on Cu(111) in scanning tunneling microscopy 
    Mehlhorn, Michael; Morgenstern, Karina (Bristol : IOP Publishing Ltd., 2009)
    Scanning tunneling microscopy imaging of amorphous and crystalline D2O ice on Cu(111) is discussed with respect to the apparent and the real heights of these structures above the metal surface. The apparent height increases ...
  • Phonons in InAs/AlAs single quantum dots observed by optical emission 
    Sarkar, D.; Van Der Meulen, H.P.; Calleja, J.M.; Becker, J.M.; Haug, Rolf J.; Pierz, Klaus (College Park, MD : American Physical Society, 2005)
    Photoluminescence emission spectra of self-assembled single InAs/AlAs quantum dots with variable size reveal typical sharp lines below 1.8 eV, corresponding to transitions between fully confined states. Above this energy ...
  • Second sound in the crossover from the Bose-Einstein condensate to the Bardeen-Cooper-Schrieffer superfluid 
    Hoffmann, Daniel K.; Singh, Vijay Pal; Paintner, Thomas; Jäger, Manuel; Limmer, Wolfgang; Mathey, Ludwig; Hecker Denschlag, Johannes ([London] : Nature Publishing Group UK, 2021)
    Second sound is an entropy wave which propagates in the superfluid component of a quantum liquid. Because it is an entropy wave, it probes the thermodynamic properties of the quantum liquid. Here, we study second sound ...
