Coexistence of valence-bond formation and topological order in the Frustrated Ferromagnetic - Chain
Cliò Efthimia Agrapidis, Stefan-Ludwig Drechsler, Jeroen van den Brink +1
Frustrated one-dimensional (1D) magnets are known as ideal playgrounds for new exotic quantum phenomena to emerge. We consider an elementary frustrated 1D system: the spin-$\frac{1…

Ordered states in the Kitaev-Heisenberg model: From 1D chains to 2D honeycomb
Cliò Efthimia Agrapidis, Jeroen van den Brink, Satoshi Nishimoto
We study the ground state of the 1D Kitaev-Heisenberg (KH) model using the density-matrix renormalization group and Lanczos exact diagonalization methods. We obtain a rich ground-s…
