Spin preservation in screw-symmetric molecules
Jonas Bloch, Fedor Baranov, Maxim Breitkreiz
In electronic transport through long molecules, spin is expected to be preserved only when the dwell time is much shorter than the characteristic spin-mixing timescale , w…
Tunneling amplifies chirality-induced spin selectivity and explains its current-direction invariance
Fedor Baranov, Virginia Gali, Gal Lemut +1
We propose a minimal model for chirality-induced spin selectivity (CISS) in dc transport through insulating chiral molecules, based on quantum tunneling and interaction-induced spi…
Long-range spin-polarized Josephson effect in ballistic S/F/S junctions with precessing magnetization
E. S. Andriyakhina, M. Mansouri, M. Breitkreiz +1
We present a theory of ballistic N/F/S and S/F/S junctions with a uniformly precessing magnetization, which generates long-range equal-spin superconducting correlations [Takahashi…
Step-Edge Anomaly in Topological Metals
Oskar Schweizer, Virginia Gali, Adam Y. Chaou +3
Bulk-boundary correspondence guarantees the presence of robust, anomalous states on the boundary of topological matter. The edges of a two-dimensional Chern insulator harbor one-di…
Magnetotransport across Weyl semimetal grain boundaries
Haoyang Tian, Vatsal Dwivedi, Adam Yanis Chaou +1
A clean interface between two Weyl semimetals features a universal, field-linear tunnel magnetoconductance of per magnetic flux quantum, where $N_\mathrm{ho}…
Quantum Oscillation Signatures of Fermi Arcs in Tunnel Magnetoconductance
Adam Yanis Chaou, Vatsal Dwivedi, Maxim Breitkreiz
Fermi-arc surface states of Weyl semimetals exhibit a unique combination of localization to a surface and connectivity to the bulk Weyl fermions that can move along the localizatio…
Axionic Instability of Periodic Weyl-Semimetal Superstructures
Tommy Li, Maxim Breitkreiz
Weyl-semimetal superstructures with a spiraling position of a pair of Weyl nodes of opposite chirality can host a chiral-symmetry preserving Fermi-arc metal state, where the chiral…
Magnetic Breakdown and Chiral Magnetic Effect at Weyl-Semimetal Tunnel Junctions
Adam Yanis Chaou, Vatsal Dwivedi, Maxim Breitkreiz
We investigate magnetotransport across an interface between two Weyl semimetals whose Weyl nodes project onto different interface momenta. Such an interface generically hosts Fermi…
Fermi-arc metals
Maxim Breitkreiz, Piet W. Brouwer
We predict a novel metallic state of matter that emerges in a Weyl-semimetal superstructure with spatially varying Weyl-node positions. In the new state, the Weyl nodes are stretch…
Surface photogalvanic effect in Weyl semimetals
J. F. Steiner, A. V. Andreev, M. Breitkreiz
The photogalvanic effect -- a rectified current induced by light irradiation -- requires the intrinsic symmetry of the medium to be sufficiently low, which strongly limits candidat…
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…
Phase shift of cyclotron orbits at type-I and type-II multi-Weyl nodes
M. Breitkreiz, N. Bovenzi, J. Tworzydlo
Quantum oscillations of response functions in high magnetic fields tend to reveal some of the most interesting properties of metals. In particular, the oscillation phase shift is s…
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…
Chirality blockade of Andreev reflection in a magnetic Weyl semimetal

Linear Response of Zero-Resistance States
Maxim Breitkreiz
A two-dimensional electron system in the presence of a magnetic field and microwave irradiation can undergo a phase transition towards a zero-resistance state. A widely used model…
Interrupted orbital motion in density-wave systems
Maxim Breitkreiz, Philip M. R. Brydon, Carsten Timm
In conventional metals, electronic transport in a magnetic field is characterized by the motion of electrons along orbits on the Fermi surface, which usually causes an increase in…

Maxim Breitkreiz, Philip M. R. Brydon, Carsten Timm
The large in-plane anisotropy of the resistivity is a hallmark of the nematic state of the iron pnictides. Solving the Boltzmann transport equation, we show that the prominent dopi…
