Magnetic Breakdown and Anomalous Quantum Oscillation in Rhombohedral Tetralayer Graphene
Jing-Yu Zhao, Yang-Zhi Chou, Sankar Das Sarma
We investigate magnetic breakdown near Van Hove singularities (VHSs) in the electron-doped rhombohedral tetralayer graphene, where chiral superconductivity has recently been report…
An asymptotically solvable model of many-body critical phases: mobility edges, scars, and inverted scars
Yi-Ting Tu, Zi-Jian Li, Sankar Das Sarma
While the prethermal regime of random many-body localized (MBL) systems is dominated by accidental many-body resonances, another class of resonances, originating from the underlyin…
Stripe-tuned superconductivity in single-flavor metals with nontrivial quantum geometry
Yi-Ting Tu, Yang-Zhi Chou, Yi Huang +1
We study how the interplay between nontrivial quantum geometry and an applied stripe potential affects superconductivity in a two-dimensional single-flavor metal. Assuming a weak c…
2D Transport in an in-plane magnetic field
Aryaman Babbar, Sankar Das Sarma
A parallel in-plane magnetic field could, in principle, distinguish between two competing physical scenarios for the experimentally observed density-tuned 2D metal-insulator transi…
Collective Spin Excitations in Correlated Moiré Chern Ferromagnets
Ming Xie, Sankar Das Sarma
Moiré-induced narrow electronic bands in transition metal dichalcogenide superlattices support many correlated quantum phases characterized by novel charge, flavor, and topological…
Disorder-induced strong-field strong-localization in 2D systems
Yi Huang, Sankar Das Sarma
A recent STM experiment in 2D bilayer graphene [Y.-C. Tsui, et al., Nature 628, 287 (2024)], under a strong perpendicular magnetic field, has made a direct observation of the exist…
