Magnetization plateaux induced by a coupling to the lattice
T. Vekua, D. C. Cabra, A. Dobry +2
We investigate a simple model of a frustrated spin-1/2 Heisenberg chain coupled to adiabatic phonons under an external magnetic field. Using field theoretic methods complemented by…

Incidence of the boundary shape in the tunnelling exponent of electrons into fractional quantum Hall edges
D. C. Cabra, N. E. Grandi
Experiments on tunneling into fractional quantum Hall droplets systematically found tunneling exponents smaller than those predicted by the ordinary chiral Luttinger liquid theory.…
