X-Ray Diffraction Observations of a Charge-Density-Wave Order in Superconducting Ortho-II YBa_{2}Cu_{3}O_{6.54} Single Crystals in Zero Magnetic Field

X-ray diffraction measurements show that the high-temperature superconductor YBa2Cu3O6.54, with ortho-II oxygen order, has charge-density-wave order in the absence of an applied magnetic field. The dominant wave vector of the charge density wave is q(CDW) ...

On field effect studies and superconductor-insulator transition in high-Tc cuprates

Davor Pavuna, Guy Joseph Günter Dubuis, Ivan Bozovic

We summarize previous field effect studies in high-T (c) cuprates and then discuss our method to smoothly tune the carrier concentration of a cuprate film over a wide range using an applied electric field. We synthesized epitaxial one-unit-cell thick films ...

Temperature and magnetic field dependence of a Kondo system in the weak coupling regime

Klaus Kern, Markus Ternes, Uta Schlickum, Peter Wahl

The Kondo effect arises due to the interaction between a localized spin and the electrons of a surrounding host. Studies of individual magnetic impurities by scanning tunneling spectroscopy have renewed interest in Kondo physics; however, a quantitative co ...

Critical Resistance at the Superconductor-Insulator Transition in Hole-Doped Cuprates

Davor Pavuna, Guy Joseph Günter Dubuis, Ivan Bozovic

Here, we show that in several p-type cuprates, the superconductor-to-insulator transition (SIT) occurs at the critical sheet resistance approximately equal to the quantum resistance of pairs, RQ=h/4

Tunneling spectra simulation of interacting Majorana wires

Ronny Thomale

Recent tunneling experiments on InSb hybrid superconductor-semiconductor devices have provided hope for a stabilization of Majorana edge modes in a spin-orbit quantum wire subject to a magnetic field and superconducting proximity effect. Connecting the exp ...

Thermopower as a Unique Tool to Probe Quantum Phase Transitions

Stevan Arsenijevic

In my thesis, transport measurements such as resistivity and, more importantly, thermopower S, were used to explore the phase diagram of bad metals. Bad metals are electronically correlated systems whose ground state lies close to a quantum phase transitio ...

Magnetic hourglass dispersion and its relation to high-temperature superconductivity in iron-tuned Fe

Henrik Moodysson Rønnow, Bastien Dalla Piazza, Arash Alahgholipour Omrani, Nikolay Tsyrulin

High-temperature superconductivity remains arguably the greatest enigma of condensed matter physics. The discovery of iron-based high-temperature superconductors [1, 2] has renewed the importance of understanding superconductivity in materials susceptible ...

The EDIPO Project: Status and Outlook

Pierluigi Bruzzone, Boris Stepanov, Rainer Wesche, Martin Vogel, Stephen Alfred March, Giancarlo Croari

The aim of this paper is to present an up to date review of the status of the European DIPOle (EDIPO) project-whose objective is to build a new facility to perform both DC and AC tests of large force flow superconductor samples in high magnetic background ...

Lifshitz critical point in the cuprate superconductor YBa_{2}Cu_{3}O_{y} from high-field Hall effect measurements

Johan Juul Chang

The Hall coefficient RH of the cuprate superconductor YBa 2Cu3Oy was measured in magnetic fields up to 60 T for a hole concentration p from 0.078 to 0.152 in the underdoped regime. In fields large enough to suppress superconductivity, RH(T) is seen to go f ...

Isotropic three-dimensional gap in the iron arsenide superconductor LiFeAs from directional heat transport measurements

Johan Juul Chang

The thermal conductivity κ of the iron-arsenide superconductor LiFeAs (Tc 18 K) was measured in single crystals at temperatures down to T50 mK and in magnetic fields up to H=17 T, very close to the upper critical field Hc218 T. For both directions of the h ...
