Metastable magnetic domains and the anomalous resistance peak in twisted double bilayer graphene
Zhenxiang Gao, Christopher Coleman, Silvia Lüscher +7
In graphene moirés, valley polarization gives rise to orbital magnetism, manifested as an anomalous Hall effect and resulting in Barkhausen jumps in longitudinal resistance when ch…
Signatures of a ferro-Josephson effect in twisted graphene
Ruiheng Su, Zhenxiang Gao, Christopher Coleman +9
When a spin-polarized current is driven across a magnetic domain wall, the resulting spin-transfer torque may, beyond a critical threshold, set the wall's moments into precession.…
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…
