Topological pumping in class-D superconducting wires

We study adiabatic pumping at a normal metal/class-D superconductor hybrid interface when superconductivity is induced through the proximity effect in a spin-orbit coupled nanowire in the presence of a tilted Zeeman field. When the induced order parameter ...

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. ...

In situ Tc measurements of cable in conduit conductors via an inductive method

Pierluigi Bruzzone, Davide Uglietti, Boris Stepanov, Ciro Calzolaio

The measurement of the actual thermal strain, epsilon th, in a cable in conduit conductor (CICC) of Nb3Sn is of paramount importance to predict the CICC performance in operation starting from the strand scaling laws for the critical current density J(c)(B, ...

Atom-specific spin mapping and buried topological states in a homologous series of topological insulators

Jan Hugo Dil

A topological insulator is a state of quantum matter that, while being an insulator in the bulk, hosts topologically protected electronic states at the surface. These states open the opportunity to realize a number of new applications in spintronics and qu ...

Superconductor–insulator transition in La2 − xSrxCuO4 at the pair quantum resistance

Davor Pavuna, Guy Joseph Günter Dubuis, Ivan Bozovic

High-temperature superconductivity in copper oxides arises when a parent insulator compound is doped beyond some critical concentration; what exactly happens at this superconductor–insulator transition is a key open question1. The cleanest approach is to t ...

Vison excitations in near-critical quantum dimer models

Dmitri Ivanov

We study vison excitations in a quantum dimer model interpolating between the Rokhsar-Kivelson models on the square and triangular lattices. In the square-lattice case, the model is known to be critical and characterized by U(1) topological quantum numbers ...

Pressure Induced Superconductivity in Pristine 1T-TiSe2

László Forró, Balazs Sipos, Helmuth Berger, Eduard Tutis

The interplay between superconductivity and the charge-density wave (CDW) state in pure 1T-TiSe2 is examined through a high-pressure study extending up to pressures of 10 GPa between sub-Kelvin and room temperatures. At a critical pressure of 2 GPa a super ...

Resonating-valence-bond physics and topological order in two dimensions: from dimer models to high-temperature superconductivity

The notion of Z(2) topological order in two-dimensional resonating-valence-bond systems is reviewed. Using quantum dimer models as an example, I discuss general properties of the topological order and the resulting vortex-like excitations (visons). Some co ...

Normal state transport properties of novel superconductors

Balazs Sipos

The discovery of high temperature superconductivity in the cuprates in 1986 has boosted the research in strongly correlated materials. One strong motivation was and stays the understanding the high-Tc phenomenon with the hope that one can ultimately engine ...
