Characterizing a high spin magnetic impurity via Andreev reflection spectroscopy
Subhajit Pal, Colin Benjamin
The ground state properties of a high spin magnetic impurity and its interaction with an electronic spin are probed via Andreev reflection. We see that through the charge and spin…
Probing helicity and the topological origins of helicity via non-local Hanbury-Brown and Twiss correlations
Arjun Mani, Colin Benjamin
Quantum Hall edge modes are chiral while quantum spin Hall edge modes are helical. However, unlike chiral edge modes which always occur in topological systems, quasi-helical edge m…
Topologically induced fractional Hall steps in the integer quantum Hall regime of
SK Firoz Islam, Colin Benjamin
The quantum magnetotransport properties of a monolayer of molybdenum disulfide are derived using linear response theory. Especially, the effect of topological terms on longitudinal…
Fragility of non-local edge mode transport in the quantum spin Hall state
Arjun Mani, Colin Benjamin
Non-local currents and voltages are better able at withstanding the deleterious effects of dephasing than local currents and voltages in nanoscale systems. This hypothesis is known…
A scheme to realize the quantum spin-valley Hall effect in monolayer graphene
SK Firoz Islam, Colin Benjamin
Quantum spin Hall effect was first predicted in graphene. However, the weak spin orbit interaction in graphene meant that the search for quantum spin Hall effect in graphene never…
