The Interplay Between Structural and Electronic Degrees of Freedom in Superconductors

More than one hundred years after the discovery of superconductivity in Leiden, the intriguing physics of several unconventional classes of superconductors continue to fascinate and challenge scientists from all over the world. The majority of these compou ...

Glassy low-energy spin fluctuations and anisotropy gap in La_{1.88}Sr_{0.12}CuO_{4}

Joël Mesot, Johan Juul Chang, Christopher Werner Matthias Robeller

We present high-resolution triple-axis neutron scattering studies of the high-temperature superconductor La1.88Sr0.12CuO4 (T-c = 27 K). The temperature dependence of the low-energy incommensurate magnetic fluctuations reveals distinctly glassy features. Th ...

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 ...

Theory of superconductivity in a three-orbital model of Sr2RuO4

Ronny Thomale, Yong Yang

In conventional and high transition temperature copper oxide and iron pnictide superconductors, the Cooper pairs all have even parity. As a rare exception, Sr2RuO4 is the first prime candidate for topological chiral p-wave superconductivity, which has time ...

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

=6.5 kΩ. In a relatively broad range of temperature ...

Electric field effect on superconductivity in $La_{2-x}$$Sr_{x}$$CuO_{4}$

Davor Pavuna, Guy Joseph Günter Dubuis, Ivan Bozovic

We demonstrate a method to tune the carrier concentration of a high temperature superconductor over a wide range, using an applied electric field. Thin film devices were made in an electrical double layer transistor configuration utilizing an ionic liquid. ...

Opening of the superconducting gap in the hole pockets of Ba(Fe1-xCox)(2)As-2 as seen via angle-resolved photoelectron spectroscopy

We present an angle-resolved photoelectron spectroscopy study of the changes in the electronic structure of electron-doped Ba(Fe1-xCox)(2)As-2 across the superconducting phase transition. By changing the polarization of the incoming light, we were able to ...

Spin density wave induced disordering of the vortex lattice in superconducting La(2−x)Sr(x)CuO(4)

Sandrine Gerber, Joël Mesot, Johan Juul Chang, Jonathan White

We use small-angle neutron scattering to study the superconducting vortex lattice in La2−xSrxCuO4 as a function of doping and magnetic field. We show that near optimally doping the vortex lattice coordination and the superconducting coherence length ξ are ...

Direct observation of competition between superconductivity and charge density wave order in YBa2Cu3O6.67

Joël Mesot, Johan Juul Chang

Superconductivity often emerges in the proximity of, or in competition with, symmetry-breaking ground states such as antiferromagnetism or charge density waves(1-5) (CDW). A number of materials in the cuprate family, which includes the high transition-temp ...
