A Crossbar Network for Silicon Quantum Dot Qubits

R. Li, L. Petit, D. P. Franke +10

The spin states of single electrons in gate-defined quantum dots satisfy crucial requirements for a practical quantum computer. These include extremely long coherence times, high-f…

Topologically protected Landau level in the vortex lattice of a Weyl superconductor

M. J. Pacholski, C. W. J. Beenakker, İ. Adagideli

The question whether the mixed phase of a gapless superconductor can support a Landau level is a celebrated problem in the context of \textit{d}-wave superconductivity, with a nega…

superconducting quantum interference through trivial edge states in InAs

Folkert K. de Vries, Tom Timmerman, Viacheslav P. Ostroukh +11

Josephson junctions defined in strong spin orbit semiconductors are highly interesting for the search for topological systems. However, next to topological edge states that emerge…

Valley-momentum locking in a graphene superlattice with Y-shaped Kekulé bond texture

O. V. Gamayun, V. P. Ostroukh, N. V. Gnezdilov +2

Recent experiments by Gutiérrez [Nature Phys. , 950 (2016)] on a graphene-copper superlattice have revealed an unusual Kekulé bond texture in the hon…

Twisted Fermi surface of a thin-film Weyl semimetal

N. Bovenzi, M. Breitkreiz, T. E. O'Brien +2

The Fermi surface of a conventional two-dimensional electron gas is equivalent to a circle, up to smooth deformations that preserve the orientation of the equi-energy contour. Here…

Fast and accurate shot noise measurements on atomic-size junctions in the MHz regime

Sumit Tewari, Carlos Sabater, Manohar Kumar +3

Shot noise measurements on atomic and molecular junctions provide rich information about the quantum transport properties of the junctions and on the inelastic scattering events ta…

Supercurrent interference in few-mode nanowire Josephson junctions

Kun Zuo, Vincent Mourik, Daniel B. Szombati +12

Junctions created by coupling two superconductors via a semiconductor nanowire in the presence of high magnetic fields are the basis for detection, fusion, and braiding of Majorana…

Robust procedure for creating and characterizing the atomic structure of scanning tunneling microscope tips

Sumit Tewari, Koen M. Bastiaans, Milan P. Allan +1

Scanning tunneling microscopes (STM) are used extensively for studying and manipulating matter at the atomic scale. In spite of the critical role of the STM tip, the control of the…

Controlling supercurrents and their spatial distribution in ferromagnets

Kaveh Lahabi, Morten Amundsen, Jabir Ali Ouassou +5

Spin-triplet Cooper pairs induced in ferromagnets form the centrepiece of the emerging field of superconducting spintronics [1,2]. Usually the focus of research is on the spin pola…

Two-terminal transport along a proximity induced superconducting quantum Hall edge

Oleksandr Gamayun, Jimmy A. Hutasoit, Vadim V. Cheianov

We study electric transport along an integer quantum Hall edge where the proximity effect is induced due to a coupling to a superconductor. Such an edge exhibits two Majorana-Weyl…

Modification of the Lifshitz-Kosevich formula for anomalous quantum oscillations in inverted insulators

Simonas Grubinskas, Lars Fritz

It is generally believed that quantum oscillations are a hallmark of a Fermi surface and the oscillations constitute the ringing of it. Recently, it was understood that in order to…

Density inhomogeneities and Rashba spin-orbit coupling interplay in oxide interfaces

N. Bovenzi, S. Caprara, M. Grilli +3

There is steadily increasing evidence that the two-dimensional electron gas (2DEG) formed at the interface of some insulating oxides like LaAlO3/SrTiO3 and LaTiO3/SrTiO3 is strongl…

Chirality blockade of Andreev reflection in a magnetic Weyl semimetal

N. Bovenzi, M. Breitkreiz, P. Baireuther +4

A Weyl semimetal with broken time-reversal symmetry has a minimum of two species of Weyl fermions, distinguished by their opposite chirality, in a pair of Weyl cones at opposite mo…

Size-effect of Kondo scattering in point contacts (revisited)

I. K. Yanson, V. V. Fisun, N. L. Bobrov +2

The size-effect of Kondo-scattering in nanometer-sized metallic point contacts is measured with the simplified, mechanically-controlled break-junction technique for CuMn alloy of d…
