Interferometry reveals spin-singlet fractional quantum Hall edges in graphene
R. Ayache, K. Kim, M. Kuiri +7
The edge modes of spin-singlet fractional quantum Hall (FQH) phases are manifestations of multicomponent topological order and SU(2) spin symmetry. An archetype is the spin-unpolar…

Magnons reveal topology and dynamics of a skyrmion crystal
Raphael Ayache, Nilotpal Chakraborty, Manabendra Kuiri +11
Although individual skyrmions are topologically protected objects, their cooperative crystalline order is fragile, easily disrupted by thermal fluctuations or other external pertur…

Competing Orders Driven by Wigner Crystal Phase in Rhombohedral Graphene
Zekang Zhou, Kilian Krötzsch, Raphaël Ayache +7
Rhombohedral graphene systems provide a unique platform where strong electronic interactions and nontrivial band topology coexist at low carrier densities and high displacement fie…
