Equilibrium current in a Weyl-semimetal - superconductor heterostructure
Kevin A. Madsen, Piet W. Brouwer, Maxim Breitkreiz
A heterostructure consisting of a magnetic Weyl semimetal and a conventional superconductor exhibits an equilibrium current parallel to the superconductor interface and perpendicul…
Chiral Anomaly Trapped in Weyl Metals: Nonequilibrium Valley Polarization at Zero Magnetic Field
Pablo M. Perez-Piskunow, Nicandro Bovenzi, Anton R. Akhmerov +1
In Weyl semimetals the application of parallel electric and magnetic fields leads to valley polarization -- an occupation disbalance of valleys of opposite chirality -- a direct co…
Determination of the Fermi surface and field-induced quasi-particle tunneling around the Dirac nodal-loop in ZrSiS
C. S. A. Müller, T. Khouri, M. R. van Delft +8
Unambiguous and complete determination of the Fermi surface is a primary step in understanding the electronic properties of topical metals and semi-metals, but only in a relatively…
Parabolic Hall Effect due to Co-Propagating Surface Modes
Maxim Breitkreiz
Real-space separations of counter-moving states to opposite surfaces or edges are associated with different types of Hall effects, such as the quantum-, spin-, or the anomalous Hal…
Large contribution of Fermi arcs to the conductivity of topological metals
Maxim Breitkreiz, Piet W. Brouwer
Surface-state contributions to the dc conductivity of most homogeneous metals exposed to uniform electric fields are usually as small as the system size is large compared to the la…
Electron-hole tunneling revealed by quantum oscillations in the nodal-line semimetal HfSiS
M. R. van Delft, S. Pezzini, T. Khouri +6
We report a study of quantum oscillations in the high-field magneto-resistance of the nodal-line semimetal HfSiS. In the presence of a magnetic field up to 31 T parallel to the c-a…
