Interplay between boundary conditions and Wilson's mass in Dirac-like Hamiltonians
A. L. Araújo, R. P. Maciel, R. G. F. Dornelas +2
Dirac-like Hamiltonians, linear in momentum , describe the low-energy physics of a large set of novel materials, including graphene, topological insulators, and Weyl fermions. W…
Spin-orbit interaction and induced superconductivity in an one-dimensional hole gas
F. K. de Vries, J. Shen, R. J. Skolasinski +11
Low dimensional semiconducting structures with strong spin-orbit interaction (SOI) and induced superconductivity attracted much interest in the search for topological superconducto…
Magnetic order induced crystal symmetry lowering in ACrO ferrimagnetic spinels
S. Bordacs, D. Varjas, I. Kezsmarki +6
We demonstrate that the onset of complex spin orders in ACrO spinels with magnetic ACo, Fe and Cu ions lowers the lattice symmetry. This is clearly indicated by the emer…
Magnetoelasticity in ACr2O4 spinel oxides
V. Kocsis, S. Bordács, D. Varjas +6
Dynamical properties of the lattice structure was studied by optical spectroscopy in ACr2O4 chromium spinel oxide magnetic semiconductors over a broad temperature region of T=10-33…
