“…most likely due to the magnetic breakdown or "orbital crossing" of the split Fermi surfaces in the non-centrosymmetric crystal structure, as reported in Yb 4 Sb 3 [13]. A similar phenomenon has been reported in several non-centrosymmetric metallic compounds, such as a cubic non-centrosymmetric uranium heavy-fermion U 3 Ni 3 Sn 4 [14] and a chiral cubic compound CrGe [15]. To clarify the electronic state of UPt 5 , we performed the energy band calculations using a full potential linear augmented plane wave (FLAPW) method with a local density approximation (LDA) for the 5 f -itinerant model.…”

We report single crystal growth of a non-centrosymmetric heavy-fermion paramagnet UPt 5 and its strongly-correlated electronic state investigated by the de Haas-van Alphen (dHvA) effect. UPt 5 crystallizes in a non-centrosymmetric cubic structure with the space group of F43m which is same as the well-known zinc-blende-or half-Heusler-type structure. We discuss detected dHvA frequencies based on the "orbital crossing" and the magnetic breakdown of the split hole Fermi surfaces pair. We also performed the energy band calculations using a local density approximation based on the 5 f-itinerant model, indicating the large density of states in the vicinity of Fermi energy E F due to the 5 f electrons.

“…A well-known indication of nearly overlapping orbits is a beating of the quantum-oscillatory wave form. Such beatings have been observed for semiconductor heterostructures (104-107), bulk semiconductors, 31 and inversion-asymmetric metals (109)(110)(111) and are most transparent in the high-temperature regime, 2π 2 k B T ∼ ε c , where the fundamental harmonic is dominant. In most experiments thus far, the periodic recurrence of beating nodes has been used to infer the magnitude of the spin-orbit coupling (105,110,111).…”

The modern scope of fermiology encompasses not just the classical geometry of Fermi surfaces but also the geometry of quantum wave functions over the Fermi surface. This enlarged scope is motivated by the advent of topological metals—metals whose Fermi surfaces are characterized by a robustly nontrivial Berry phase. We review the extent to which topological metals can be diagnosed from magnetic-field-induced quantum oscillations of transport and thermodynamic quantities. A holistic analysis of the oscillatory wave form is proposed, in which different characteristics of the wave form (e.g., phase offset, high-harmonic amplitudes, temperature-dependent frequency) encode different aspects of a topologically nontrivial Fermi surface. Which characteristic to focus on depends on ( a) the orientation of the magnetic field relative to certain crystallographic axes, ( b) the symmetry class of the topological metal, and ( c) the separation of Fermi-surface pockets in quasimomentum k space. Closely proximate pockets arise when (1) spin–split pockets are nearly overlapping due to a weak spin–orbit force or when (2) two pockets touch at an isolated k point, which can be a topological band-touching point or a saddlepoint in the energy-momentum dispersion. The emergence of a pseudospin degree of freedom (in case 1) and the implications of magnetic breakdown (in case 2) are reviewed, with emphasis on new aspects originating from the (nonabelian) Berry connection of the Fermi surface. Future extensions of topofermiology are suggested in the directions of interaction-induced Fermi-liquid instabilities and two-dimensional electron liquids. Expected final online publication date for the Annual Review of Condensed Matter Physics, Volume 14 is March 2023.

“…Such beatings have been observed for semiconductor heterostructures [67][68][69] and inversion-asymmetric metals [70][71][72]. In most experiments, the beating has been used to infer the magnitude of the spin-orbit coupling [67,71,72]; some of these experiments [67] paid attention to the aperiodicity of the beating, and attributed it phenomenologically to a B-dependent splitting of the two orbits, which have distinct frequencies f 1 and f 2 in 1/B.…”

Landau quantization of nearly degenerate bands and full symmetry classification of Landau level crossings

et al. 2019

Semiclassical quantization rules compactly describe the energy dispersion of Landau levels, and are predictive of quantum oscillations in transport and thermodynamic quantities. Such rules -as formulated by Onsager, Lifshitz and Roth -apply when the spin-orbit interaction dominates over the Zeeman interaction (or vice versa), but does not generally apply when the two interactions are comparable in strength. In this work, we present a generalized quantization rule which treats the spin-orbit and Zeeman interactions on equal footing, and therefore has wider applicability to spinorbit-coupled materials lacking a spatial inversion center, or having magnetic order. More generally, our rule describes the Landau quantization of any number of nearly degenerate energy bands -in any symmetry class. The resultant Landau-level spectrum is generically non-equidistant but may contain spin (or pseudospin) degeneracies. To tune to such degeneracies in the absence of crystalline point-group symmetries, three real parameters are needed. We have exhaustively identified all symmetry classes of cyclotron orbits for which this number is reduced from three, thus establishing symmetry-enforced 'non-crossing rules' for Landau levels. In particular, only one parameter is needed in the presence of spatial rotation or inversion; this single parameter may be the magnitude or orientation of the field. Signatures of single-parameter tunability include (i) a smooth crossover between period-doubled and -undoubled quantum oscillations in the low-temperature Shubnikov-de Haas effect, as well as (ii) 'magic-angle' magnetoresistance oscillations. We demonstrate the utility of our quantization rule, as well as the tunability of Landau-level degeneracies, for the Rashba-Dresselhaus two-dimensional electron gas -subject to an arbitrarily oriented magnetic field. arXiv:1810.01908v2 [cond-mat.mes-hall]
