Intrinsic Time-reversal-invariant Topological Superconductivity in Thin Films of Iron-based Superconductors
Rui-Xing Zhang, S. Das Sarma
We establish quasi-two-dimensional thin films of iron-based superconductors (FeSCs) as a new high-temperature platform for hosting intrinsic time-reversal-invariant helical topolog…
Disorder effects on Majorana zero modes: Kitaev chain versus semiconductor nanowire
Haining Pan, S. Das Sarma
Majorana zero modes in a superconductor-semiconductor nanowire have been extensively studied during the past decade. Disorder remains a serious problem, preventing the definitive o…
Hydrodynamic sound and plasmons in three dimensions
Shao-Kai Jian, Sankar Das Sarma
In a recent paper by Lucas and Das Sarma [Physical Review B 97, 115449 (2018)], a solvable model of collective modes in 2D metals was considered in the hydrodynamic regime. In the…
Interaction-Driven Filling-Induced Metal-Insulator Transitions in 2D Moiré Lattices
Haining Pan, Sankar Das Sarma
Using a realistic band structure for twisted WSe materials, we develop a theory for the interaction-driven correlated insulators to conducting metals transitions through the t…
Anomalous Floquet Chiral Topological Superconductivity in a Topological Insulator Sandwich Structure
Rui-Xing Zhang, S. Das Sarma
We show that Floquet chiral topological superconductivity arises naturally in Josephson junctions made of magnetic topological insulator-superconductor sandwich structures. The Jos…
Three-terminal nonlocal conductance in Majorana nanowires: Distinguishing topological and trivial in realistic systems with disorder and inhomogeneous potential
Haining Pan, Jay D. Sau, S. Das Sarma
We develop a theory for the three-terminal nonlocal conductance in Majorana nanowires as existing in the superconductor-semiconductor hybrid structures in the presence of supercond…
