Spontaneous Formation of Altermagnetism from Orbital Ordering
Valentin Leeb, Alexander Mook, Libor Šmejkal +1
Altermagnetism has emerged as a third type of collinear magnetism. In contrast to standard ferromagnets and antiferromagnets, altermagnets exhibit extra even-parity wave spin order…
Realizing Altermagnetism in Fermi-Hubbard Models with Ultracold Atoms
Purnendu Das, Valentin Leeb, Johannes Knolle +1
Altermagnetism represents a type of collinear magnetism, that is in some aspects distinct from ferromagnetism and from conventional antiferromagnetism. In contrast to the latter, s…
Interband scattering- and nematicity-induced quantum oscillation frequency in FeSe
Valentin Leeb, Johannes Knolle
Understanding the nematic phase observed in the iron-chalcogenide materials is crucial for describing their superconducting pairing. Experiments on FeSeS showed that on…
Quantum Oscillations of the Quasiparticle Lifetime in a Metal
Nico Huber, Valentin Leeb, Andreas Bauer +4
Following nearly a century of research, it remains a puzzle that the low-lying excitations of metals are remarkably well explained by effective single-particle theories of non-inte…
Theory of Difference Frequency Quantum Oscillations
Valentin Leeb, Johannes Knolle
Quantum oscillations (QO) describe the periodic variation of physical observables as a function of inverse magnetic field in metals. The Onsager relation connects the basic QO freq…
Quantum oscillations in a doped Mott insulator beyond Onsager's relation
Valentin Leeb, Johannes Knolle
The kinetic energy of electrons in a magnetic field is quenched resulting in a discrete set of highly degenerate Landau levels (LL) which gives rise to fascinating phenomena like t…
