Probing momentum-dependent scattering in uniaxially stressed SrRuO through the Hall effect
Po-Ya Yang, Hilary M. L. Noad, Mark E. Barber +4
Under in-plane uniaxial stress, the largest Fermi surface sheet of the correlated metal SrRuO undergoes a Lifshitz transition from an electron-like to an open geometry. We…
Correlated Hofstadter Spectrum and Flavor Phase Diagram in Magic Angle Graphene
Jiachen Yu, Benjamin A. Foutty, Zhaoyu Han +8
In magic angle twisted bilayer graphene (MATBG), the moiré superlattice potential gives rise to narrow electronic bands1 which support a multitude of many-body quantum phases. Furt…
Intrinsic one-dimensional conducting channels in the Kondo insulator SmB6
Ke-Jun Xu, Mark Barber, Eric Yue Ma +5
Since its discovery as a Kondo insulator 50 years ago, SmB6 recently received a revival of interest due to detection of unexpected quantum oscillations in the insulating state, dis…
A key role of correlation effects in the Lifshitz transition in SrRuO
Mark E. Barber, Frank Lechermann, Sergey V. Streltsov +8
Uniaxial pressure applied along an Ru-Ru bond direction induces an elliptical distortion of the largest Fermi surface of SrRuO, eventually causing a Fermi surface topologic…
Direct Observation of a Uniaxial Stress-driven Lifshitz Transition in SrRuO
V. Sunko, E. Abarca Morales, I. Marković +11
Pressure represents a clean tuning parameter for traversing the complex phase diagrams of interacting electron systems and as such has proved of key importance in the study of quan…
Resistivity in the Vicinity of a Van Hove Singularity: SrRuO Under Uniaxial Pressure
Mark E. Barber, Alexandra S. Gibbs, Yoshiteru Maeno +2
We report the results of a combined study of the normal state resistivity and superconducting transition temperature of the unconventional superconductor SrRuO under…
