DOI: 10.1103/physrevb.102.155106
Abstract: Here, the resistance of a WSe${}_{2}$ monolayer is measured under a strong, pulsed magnetic field. Non-$\frac{1}{B}$-periodic Shubnikov--de Haas oscillations are observed and attributed to a large spin-valley splitting of the valence band. The authors develop… read more here.

DOI: 10.1103/physrevlett.120.076801
Abstract: The widely reported magnetoresistance oscillations in LaAlO_{3}/SrTiO_{3} heterostructures have invariably been attributed to the Shubnikov-de Haas (SdH) effect, despite a pronounced inconsistency with low-field Hall resistance measurements. Here we report SdH-like resistance oscillations in quasi-1D… read more here.
