  1. 18. Impurity as a witness of a few- to many-body crossover in low-dimensional degenerate gases
    Dr Artem Volosniev (Institute of Science and Technology Austria (ISTA))

    Invited Talk

    Impurity atoms or molecules are often used by theorists and experimenters for studying a crossover from few to many-body physics in condensed matter systems, such as superfluid helium and ultracold degenerate gases. The presentation will offer a few examples of such studies in the context of quasi-one- and two-dimensional cold-atom systems with impurities. These examples provide insight into...

  2. 146. Structure and field-induced dynamics of small helium clusters
    Dr Maksim Kunitski (Goethe-Universität Frankfurt am Main)

    Invited Talk

    Small helium clusters are peculiar few body quantum systems. The helium dimer has a single weakly bound state of a huge spatial extent. About 80% of its probability distribution resides in the classically forbidden tunneling region [1]. This is why such objects are termed “quantum halos”. The helium trimer has two bound states, excited one of which is of Efimov nature [2]. We utilize...

  3. 100. Exotic pairing in few-body ultracold systems

    Contributed Talk

    A system of a few attractively interacting atoms of lithium in one-dimensional harmonic confinement is investigated. Non-trivial interparticle correlations induced by interactions in a particle-imbalanced system are studied in the framework of the noise correlation. In this way, it is shown that evident signatures of strongly correlated fermionic pairs in the Fulde-Ferrell-Larkin-Ovchinnikov...

    Three-body ${\rm CsH_2}$ eigenvalues in a cuboctahedron CsH$_2$Pd$_{12}$ molecule are calculated in the range from 0.01fm to several ten nano-meter in one stretch, by using 100 significant figure. We utilized five traditional potentials (nuclear Woods-Saxon, three-ion repulsive Coulomb, ion-Pd...

  5. 49. Transverse motion of diffraction wavelets in a matter-wave beam-splitter
    Oleksandr Marchukov (Institut für Angewandte Physik, TU Darmstadt)

    Contributed Talk

    Matter-wave interferometry with Bose-Einstein condensates (BECs) is a rapidly developing tool for precision measurements [1]. A crucial element of matter-wave interferometers is a beam-splitter that employs the interaction of atoms with laser beams and creates superposition of macroscopically occupied momentum states.

    We consider the Bragg beam-splitting of an off-axis BEC with...
