Realization of an atomic quantum Hall system in four dimensions
Modern condensed matter physics relies on the concept of topology to classify matter, from quantum Hall systems to topological insulators. Engineered systems, benefiting from synthetic dimensions, can potentially give access to topological states predicted ...
Amer Assoc Advancement Science2024Magneto-Thermoelectric Transport in Graphene Quantum Dot with Strong Correlations
Disorder at etched edges of graphene quantum dots (GQD) enables random all-to-all interactions between localized charges in partially filled Landau levels, providing a potential platform to realize the Sachdev-Ye-Kitaev (SYK) model. We use quantum Hall edg ...
2024Thouless pumping in Josephson junction arrays
Recent advancements in fabrication techniques have enabled unprecedented clean interfaces and gate tunability in semiconductor-superconductor heterostructures. Inspired by these developments, we propose protocols to realize Thouless quantum pumping in elec ...
Scipost Foundation2024Investigation of thermoelectric nanomaterials
Thermoelectric conversion remains an active research field in light of its potential to enhance energy efficiency by waste heat recovery in a noise and wear-free manner.Nanostructuring is responsible for most of the recently reported improvements of the fi ...
EPFL2023Anomalous Hall effect and magnetic structure of the topological semimetal (Mn0.78Fe0.22)3Ge
Me3+8Ge, being a Weyl semimetal, shows a large anomalous Hall effect (AHE), which decreases slowly with an increase in 8 from 0.1 to 0.4. However, AHE in this compound remains significantly large in the whole range of 8 because of the robust nature of the ...
AMER PHYSICAL SOC2023Isolated ballistic non-abelian interface channel
The topological order of a quantum Hall state is mirrored by the gapless edge modes owing to bulk-edge correspondence. The state at the filling of ν = 5/2, predicted to host non-abelian anyons, supports a variety of edge modes (integer, fractional, neutral ...
