Moiré miniband features in the angle-resolved photoemission spectra of graphene/hBNheterostructures

The angle-resolved photoemission spectra of uranium based ferromagnets

We investigate the spin-split and magnetization dependence of the 5f angle resolved photoemission spectra. For large values of the spontaneous magnetization, the model supports magnetic polaron excitations. We compare the results of our calculations with recent experimental results of Durakiewicz, Joyce and co-workers on related 5f compounds.

Angle-resolved photoemission spectra of the Hubbard model

We discuss spectra calculated for the two-dimensional Hubbard model in the intermediate coupling regime with the dynamical cluster approximation, which is a nonperturbative approach. We find a crossover from a normal Fermi liquid with a Fermi surface closed around the Brillouin-zone center at large doping to a nonFermi liquid for small doping where the Fermi surface is holelike, closed around M...

Angle resolved resonant photoemission in transition metals

Angle-resolved photoemission study of Sr2RuO4.

We present high-resolution ~HR! angle-resolved photoemission spectroscopy ~ARPES! measurements of the noncuprate layered perovskite superconductor Sr2RuO4 . ARPES spectra of the whole valence-band region obtained along two high-symmetry directions in the Brillouin zone show clear dispersion, generally similar to that of a band calculation. However, HRARPES measurements taken in the vicinity of ...
