Scattering theory of the chiral magnetic effect in a Weyl semimetal: Interplay of bulk Weyl cones and surface Fermi arcs
P. Baireuther, J. A. Hutasoit, J. Tworzydło +1
We formulate a linear response theory of the chiral magnetic effect in a finite Weyl semimetal, expressing the electrical current density induced by a slowly oscillating magnet…
Mechanical Weyl Modes in Topological Maxwell Lattices
D. Zeb Rocklin, Bryan Gin-ge Chen, Martin Falk +2
Topological mechanical structures exhibit robust properties protected by topological invariants. In this letter, we study a family of deformed square lattices that display topologi…
Self-organized pseudo-graphene on grain boundaries in topological band insulators
Robert-Jan Slager, Vladimir Juricic, Ville Lahtinen +1
Semi-metals are characterized by nodal band structures that give rise to exotic electronic properties. The stability of Dirac semi-metals, such as graphene in two spatial dimension…
Spin-mediated dissipation and frequency shifts of a cantilever at milliKelvin temperatures
A. M. J. den Haan, J. J. T. Wagenaar, J. M. de Voogd +2
We measure the dissipation and frequency shift of a magnetically coupled cantilever in the vicinity of a silicon chip, down to mK. The dissipation and frequency shift originat…
Dissipation and resonance frequency shift of a resonator magnetically coupled to a semiclassical spin
J. M. de Voogd, J. J. T. Wagenaar, T. H. Oosterkamp
We calculate the change of the properties of a resonator, when coupled to a semiclassical spin by means of the magnetic field. Starting with the Lagrangian of the complete system,…
Effect of a tunnel barrier on the scattering from a Majorana bound state in an Andreev billiard
M. Marciani, H. Schomerus, C. W. J. Beenakker
We calculate the joint distribution of the scattering matrix and time-delay matrix of a chaotic quantum dot coupled by point contacts to me…
Waiting times of entangled electrons in normal-superconducting junctions
M. Albert, D. Chevallier, P. Devillard
We consider a normal-superconducting junction in order to investigate the effect of new physical ingredients on waiting times. First, we study the interplay between Andreev and spe…
Degeneracies and fluctuations of Néèl skyrmions in confined geometries
Rick Keesman, A. O. Leonov, P. van Dieten +4
The recent discovery of tunable Dzyaloshinskii-Moriya interactions in layered magnetic materials with perpendicular magnetic anisotropy makes them promising candidates for stabiliz…
Topologically protected charge transfer along the edge of a chiral -wave superconductor
N. V. Gnezdilov, B. van Heck, M. Diez +2
The Majorana fermions propagating along the edge of a topological superconductor with pairing deliver a shot noise power of per eV of voltage b…
Statistical translation invariance protects a topological insulator from interactions
A. Milsted, L. Seabra, I. C. Fulga +2
We investigate the effect of interactions on the stability of a disordered, two-dimensional topological insulator realized as an array of nanowires or chains of magnetic atoms on a…
Impurity Bound States and Greens Function Zeroes as Local Signatures of Topology
Robert-Jan Slager, Louk Rademaker, Jan Zaanen +1
We show that the local in-gap Greens function of a band insulator , with the position perpendicular…
Probing the magnetic moment of FePt micromagnets prepared by Focused Ion Beam milling
H. C. Overweg, A. M. J. den Haan, H. J. Eerkens +5
We investigate the degradation of the magnetic moment of a 300 nm thick FePt film induced by Focused Ion Beam (FIB) milling. A rod is milled ou…
Confinement-deconfinement transition due to spontaneous symmetry breaking in quantum Hall bilayers
D. I. Pikulin, P. G. Silvestrov, T. Hyart
Band-inverted electron-hole bilayers support quantum spin Hall insulator and exciton condensate phases. We investigate such a bilayer in an external magnetic field. We show that th…

We report the realization of quantum microwave circuits using hybrid superconductor-semiconductor Josephson elements comprised of InAs nanowires contacted by NbTiN. Capacitively-sh…
Superlubric to stick-slip sliding of incommensurate graphene flakes on graphite
M. M. van Wijk, M. Dienwiebel, J. W. M. Frenken +1
We calculate the friction of fully mobile graphene flakes sliding on graphite. For incommensurately stacked flakes, we find a sudden and reversible increase in friction with load,…
Quench dynamics of fermion-parity switches in a Josephson junction
B. Tarasinski, D. Chevallier, Jimmy A. Hutasoit +2
A Josephson junction may be driven through a transition where the superconducting condensate favors an odd over an even number of electrons. At this switch in the ground-state ferm…
Modeling contact formation between atomic-sized gold tips via molecular dynamics
W. Dednam, C. Sabater, M. A. Fernandez +3
The formation and rupture of atomic-sized contacts is modelled by means of molecular dynamics simulations. Such nano-contacts are realized in scanning tunnelling microscope and mec…
Ballistic Josephson junctions in edge-contacted graphene
