A binary black hole merger rate comparison within the same metallicity - star formation rate framework
Lumen Boco, Michele Bosi, Cecilia Sgalletta +2
Recent studies have suggested that binary population synthesis models, when coupled with observationally based, metallicity-dependent star formation rate density, overpredict the o…
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…
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 Å mejkal
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…
Gauge-invariant projector calculus for quantum state geometry and applications to observables in crystals
Johannes Mitscherling, Alexander Avdoshkin, Joel E. Moore
The importance of simple geometrical invariants, such as the Berry curvature and quantum metric, constructed from the Bloch states of a crystal has become well-established over fou…
The multi-state geometry of shift current and polarization
Alexander Avdoshkin, Johannes Mitscherling, Joel E. Moore
The quantum metric and Berry curvature capture essential properties of non-trivial Bloch states and underpin many fascinating phenomena. However, it becomes increasingly evident th…
