Apparent inconsistency between Streda formula and Hall conductivity in reentrant integer quantum anomalous Hall effect in twisted MoTe
Yi Huang, Seth Musser, Jihang Zhu +2
Recent experiments in twisted bilayer MoTe (tMoTe) have uncovered a rich landscape of correlated phases. In this work, we investigate the reentrant integer quantum anomalou…
Singlet-only Always-on Gapless Exchange Qubits with Baseband Control
Nathan L. Foulk, Silas Hoffman, Katharina Laubscher +1
We propose a singlet-only always-on gapless exchange (SAGE) spin qubit that encodes a single qubit in the spins of four electrons while allowing universal baseband control. While c…
Integer Quantum Hall Effect: Disorder, temperature, floating, and plateau width
Stuart Yi-Thomas, Yi Huang, Jay D. Sau +1
We theoretically consider disorder and temperature effects on the integer quantum Hall effect (IQHE) using a variety of distinct and complementary analytical and numerical techniqu…
Intravalley spin-polarized superconductivity in rhombohedral tetralayer graphene
Yang-Zhi Chou, Jihang Zhu, Sankar Das Sarma
We study the intravalley spin-polarized superconductivity in rhombohedral tetralayer graphene, which has been discovered experimentally in Han arXiv:2408.15233. We constr…
Vision transformer based Deep Learning of Topological indicators in Majorana Nanowires
Jacob R. Taylor, Sankar Das Sarma
1D superconductor-semiconductor nanowires are the leading candidates for topological quantum computation due to their ability to host non-Abelian Majorana zero modes (MZMs). Howeve…
Fractional quantum anomalous Hall effect in rhombohedral multilayer graphene with a strong displacement field
Ke Huang, Sankar Das Sarma, Xiao Li
We investigate the fractional quantum anomalous Hall (FQAH) effect in rhombohedral multilayer graphene (RnG) in the presence of a strong applied displacement field. We first introd…
