Hall viscosity and hydrodynamic inverse Nernst effect in graphene
Zhuo-Yu Xian, Sven Danz, David Rodríguez Fernández +6
Motivated by Hall viscosity measurements in graphene sheets, we study hydrodynamic transport of electrons in a channel of finite width in external electric and magnetic fields. We…
Interplay of Band Geometry and Topology in Ideal Chern Insulators in Presence of External Electromagnetic Fields
Christian Northe, Giandomenico Palumbo, Jonathan Sturm +2
Ideal Chern insulating phases arise in two-dimensional systems with broken time-reversal symmetry. They are characterized by having nearly-flat bands, and a uniform quantum geometr…
Temperature and Chemical Potential Dependence of the Parity Anomaly in Quantum Anomalous Hall Insulators
C. Tutschku, F. S. Nogueira, C. Northe +2
The low-energy physics of two-dimensional Quantum Anomalous Hall insulators like (Hg,Mn)Te quantum wells or magnetically doped (Bi,Sb)Te thin films can be effectively described by…
Momentum-Dependent Mass and AC Hall Conductivity of Quantum Anomalous Hall Insulators and Their Relation to the Parity Anomaly
Christian Tutschku, Jan Böttcher, René Meyer +1
The Dirac mass of a two-dimensional QAH insulator is directly related to the parity anomaly of planar quantum electrodynamics, as shown initially in Phys. Rev. Lett. 52, 18 (1984).…
Fate of Quantum Anomalous Hall Effect in the Presence of External Magnetic Fields and Particle-Hole Asymmetry
Jan Böttcher, Christian Tutschku, Ewelina M. Hankiewicz
The quantum anomalous Hall (QAH) effect, a condensed matter analog of the parity anomaly, is characterized by a quantized Hall conductivity in the absence of an external magnetic f…
Topological Quantum Computing Using Nanowire Devices
C. Tutschku, R. W. Reinthaler, C. Lei +2
The boundary of topological superconductors might lead to the appearance of Majorana edge modes, whose non-trivial exchange statistics can be used for topological quantum computing…
