  • Lechtenfeld, Olaf; Nampuri, Suresh (Amsterdam : Elsevier, 2016)
    We extract the leading-order entropy of a four-dimensional extremal black hole in N=2N=2 ungauged supergravity by formulating the CFT1 that is holographically dual to its near-horizon AdS2 geometry, in terms of a rational ...
  • Baranov, M.A.; Dobrek, L.; Lewenstein, M. (Bristol : IOP Publishing Ltd., 2004)
    We present a detailed study of the BCS pairing transition in a trapped polarized dipolar Fermi gas. In the case of a shallow nearly spherical trap, we find a decrease in the transition temperature as a function of the trap ...
  • Wollweber, Merve (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)
    Many optical modalities are being investigated, applied, and further developed for non-invasive analysis and sensing in the life sciences. Often, the combination of two or more modalities is required for in depth analysis ...
  • Miroshnichenko, Andrey E.; Evlyukhin, Andrey B.; Yu, Ye Feng; Bakker, Reuben M.; Chipouline, Arkadi; Kuznetsov, Arseniy I.; Luk'yanchuk, Boris; Chichkov, Boris; Kivshar, Yuri S. (London : Nature Publishing Group, 2015)
    Nonradiating current configurations attract attention of physicists for many years as possible models of stable atoms. One intriguing example of such a nonradiating source is known as "anapole". An anapole mode can be ...
  • Vahlbruch, H.; Chelkowski, S.; Danzmann, Karsten; Schnabel, R. (Bristol : IOP Publishing Ltd., 2007)
    We report the experimental realization of squeezed quantum states of light, tailored for new applications in quantum communication and metrology. Squeezed states in a broad Fourier frequency band down to 1 Hz have been ...
  • Azimi, M.; Chotorlishvili, L.; Mishra, S.K.; Vekua, Teimuraz; Huebner, W.; Berakdar, J. (Bristol : IOP Publishing Ltd., 2014-06-12)
    We study a quantum Otto engine operating on the basis of a helical spin-1/2 multiferroic chain with strongly coupled magnetic and ferroelectric order parameters. The presence of a finite spin chirality in the working ...
  • Beny, Cedric; Osborne, Tobias J. (Bristol : IOP Publishing Ltd., 2015-08-05)
    In physics, one attempts to infer the rules governing a system given only the results of imperfect measurements. Hence, microscopic theories may be effectively indistinguishable experimentally. We develop an operationally ...
  • Ulmanis, J.; Haefner, S.; Pires, R.; Kuhnle, E. D.; Weidemueller, M.; Tiemann, Eberhard (Bristol : IOP Publishing Ltd., 2015-05-07)
    We study the interspecies scattering properties of ultracold Li-Cs mixtures in their two energetically lowest spin channels in the magnetic field range between 800 and 1000 G. Close to two broad Feshbach resonances (FR) ...
