de Haas–van Alphen effect in superconductors
A theory of the de Haas–van Alphen effect in type-II superconductors is proposed. The effect of the electron scattering by nonmagnetic impurities in a magnetic field in the potential produced by a nonuniform distribution of the order parameter in a mixed state is investigated. The magnitude of the order parameter and quasiparticle density of states are determined from the solution of the system...
متن کاملPhotonic de Haas-van Alphen effect.
Based on the recently proposed concept of effective gauge potential and magnetic field for photons, we numerically demonstrate a photonic de Haas-van Alphen effect. We show that in a dynamically modulated photonic resonator lattice exhibiting an effect magnetic field, the trajectories of the light beam at a given frequency have the same shape as the constant energy contour for the photonic band...
متن کاملde Haas-van Alphen effect in single crystal MgB2.
We report observations of quantum oscillations in single crystals of the high temperature superconductor MgB2. Three de Haas-van Alphen frequencies are clearly resolved. Comparison with band structure calculations strongly suggests that two of these come from a single warped Fermi surface tube along the c direction, and that the third arises from cylindrical sections of an in-plane honeycomb ne...
متن کاملBerry phase and de Haas-van Alphen effect in LaRhIn5.
We explain the experimental data on the magnetization of LaRhIn5 recently published by Goodrich et al. [Phys. Rev. Lett. 89, 026401 (2002)]]. We show that the magnetization of a small electron group associated with a band-contact line was detected in that Letter. These data provide the first observation of the Berry phase of electrons in metals via the de Haas-van Alphen effect.
متن کاملDe Haas–van Alphen effect in unconventional superconductors
A theory of the de Haas–van Alphen effect in type-II p-wave and D-wave superconductors ~the latter corresponds to the B1g one-dimensional representation of group D4h) has been developed. Solutions for the order parameter and density of quasiparticle states near the upper critical field have been calculated. If the curve enclosing the extremal cross section of the Fermi surface in the plane perp...
