  • A space-based quantum gas laboratory at picokelvin energy scales 
    Gaaloul, Naceur; Meister, Matthias; Corgier, Robin; Pichery, Annie; Boegel, Patrick; Herr, Waldemar; Ahlers, Holger; Charron, Eric; Williams, Jason R.; Thompson, Robert J.; Schleich, Wolfgang P.; Rasel, Ernst M. ([London] : Nature Publishing Group UK, 2022)
    Ultracold quantum gases are ideal sources for high-precision space-borne sensing as proposed for Earth observation, relativistic geodesy and tests of fundamental physical laws as well as for studying new phenomena in ...
  • BCS pairing in a trapped dipolar Fermi gas 
    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 ...
  • A Calogero formulation for four-dimensional black-hole microstates 
    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 ...
  • Detection of the 5p – 4f orbital crossing and its optical clock transition in Pr9+ 
    Bekker, H.; Borschevsky, A.; Harman, Z.; Keitel, C.H.; Pfeifer, T.; Schmidt, P.O.; Crespo López-Urrutia, J.R.; Berengut, J.C. ([London] : Nature Publishing Group UK, 2019)
    Recent theoretical works have proposed atomic clocks based on narrow optical transitions in highly charged ions. The most interesting candidates for searches of physics beyond the Standard Model are those which occur at ...
  • Multimodal optical spectroscopy for application in the life sciences 
    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 ...
  • Nonradiating anapole modes in dielectric nanoparticles 
    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 ...
  • Quantum engineering of squeezed states for quantum communication and metrology 
    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 ...
  • Quantum Otto heat engine based on a multiferroic chain working substance 
    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 ...
  • The renormalization group via statistical inference 
    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 ...
  • Universality of weakly bound dimers and Efimov trimers close to Li-Cs Feshbach resonances 
    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) ...
