  1. Superfluid Density Measurements of High-Temperature Superconducting Films

    Osborn, Kevin Daniel2012

    … inductive system suitable for measuring the superfluid density of superconducting films. With this system we measure several intrinsic properties of YBa2Cu3O7-x (YBCO) and Bi2Sr2CaCu2O8+δ (Bi-2212) films. Two competing models of the pseudogap are compared to the temperature dependence of the …

  3. Superfluidity in a uniform two-dimensional Bose gas

    Christodoulou, PanagiotisUniversity of Cambridge2021

    … thesis describes experimental studies regarding superfluidity in a two-dimensional gas of ultracold atoms trapped in a uniform potential. It is conceptually divided into three parts. In the first part we offer a theoretical discussion of a superfluid, first from a general perspective and then …

  4. Pairing and Superfluid Properties of Polarized Dilute Fermion Gases in the Bcs-Bec Crossover

    Akkineni, VamsiUniversity of Illinois at Urbana-Champaign2015

    … with the R-PIMC method, calculating the energy, superfluid density, and structural properties, at several points in the space of the control variables. We then attempt to identify the phase diagram of this system, and to characterize the phases.

  5. Characterization of Magic-angle Twisted Bilayer Graphene using Microwave Techniques

    Dinh, Thao H.Massachusetts Institute of Technology2021

    … utilized to measure MATBG kinetic inductance and superfluid density in a non-invasive manner. This experiment will also be a crucial step towards realizing MATBG-based superconducting qubit circuits.

  6. Sound Waves and Turbulence in Two-dimensional Bose Gases

    Galka, MaciejUniversity of Cambridge2022

    … box trap, which guarantees the homogeneous gas density and allows tuneability of the interaction strength. We begin with the studies of the propagation of sound. For temperatures below the BKT critical temperature, we observe first and second sound, as predicted by the hydrodynamic two-fluid …

  7. Penetration depth measurements of organic superconductors

    Olheiser, Tyson A.University of Illinois at Urbana-Champaign2010

    … Also, the temperature dependence of the superfluid density was similar to in-plane behavior, suggesting that interplane transport in these materials is coherent despite being highly anisotropic and definitely 2D in nature.

  8. Quantized vortices in arbitrary dimensions and the normal-to-superfluid phase transition

    Bora, FlorinUniversity of Illinois at Urbana-Champaign2010

    … are explored in the general setting of a superfluid in arbitrary dimensions. The vortices may be idealized as objects of co-dimension two, such as one-dimensional loops and two-dimensional closed surfaces, respectively, in the cases of three- and four-dimensional superfluidity. By using …

  9. Two-dimensional superconducting states near zero temperature quantum phase transitions

    Urban, LukasUniversity of Illinois at Urbana-Champaign2011

    … conductivity of the 2D films, which probes the superfluid response. Using a contactless technique, we have been able to measure the superconducting transition as a function of temperature and demonstrate the existence of a Kosterlitz-Thouless (KT) transition in zero magnetic field. Applying a …
