Identifying Chern numbers of superconductors from local measurements
Paul Baireuther, Marcin Płodzień, Teemu Ojanen +2
Fascination in topological materials originates from their remarkable response properties and exotic quasiparticles which can be utilized in quantum technologies. In particular, la…
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…
Weyl-Majorana solenoid
P. Baireuther, J. Tworzydło, M. Breitkreiz +2
A Weyl semimetal wire with an axial magnetization has metallic surface states (Fermi arcs) winding along its perimeter, connecting bulk Weyl cones of opposite topological charge (B…
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…
Manipulation of a two-photon pump in superconductor - semiconductor heterostructures
Paul Baireuther, Peter P. Orth, Ilya Vekhter +1
We investigate the photon statistics, entanglement and squeezing of a pn-junction sandwiched between two superconducting leads, and show that such an electrically-driven photon pum…
