Microscopic origin of -wave magnetism
Johannes Mitscherling, Jan Priessnitz, Clara K. Geschner +1
-, -, or -wave antialtermagnets yield large non-relativistic spin splitting with out-of-plane spin polarization in momentum space perpendicular to the coplanar non-colline…
Orbital magnetization from parallel transport of Bloch states
Johannes Mitscherling, Jan Priessnitz, Libor Šmejkal
Quantum geometric formulations of linear and nonlinear responses can be constructed from a single building block in the form of a gauge-invariant interband transition operator. Her…
Quantum Geometric Origin of the Intrinsic Nonlinear Hall Effect
Yannis Ulrich, Johannes Mitscherling, Laura Classen +1
We decompose the intrinsic second-order nonlinear Hall effect (NLHE) of a generic multiband system into its quantum-geometric contributions within a fully quantum-mechanical, proje…
Symmetry-enforced double Weyl points, multiband quantum geometry, and singular flat bands of doping-induced states at the Fermi level
Moritz M. Hirschmann, Johannes Mitscherling
Two common difficulties in the design of topological quantum materials are that the desired features lie too far from the Fermi level and are spread over a too-large energy range.…
Nontrivial quantum geometry of degenerate flat bands
Bruno Mera, Johannes Mitscherling
The importance of the quantum metric in flat-band systems has been noticed recently in many contexts such as the superfluid stiffness, the dc electrical conductivity, and ideal Che…
Bound on resistivity in flat-band materials due to the quantum metric
Johannes Mitscherling, Tobias Holder
The quantum metric is a central quantity of band theory but has so far not been related to many response coefficients due to its nonclassical origin. However, within a newly develo…
Non-linear conductance in mesoscopic weakly disordered wires -- Interaction and magnetic field asymmetry
Christophe Texier, Johannes Mitscherling
We study the non-linear conductance in coherent quasi-1D weakly disordered metallic wires. The analysis is based on the calculation…
