Field-induced incommensurate ordering in the Heisenberg chains coupled by Ising interaction: Model for the ytterbium aluminum perovskite YbAlO
Cliò Efthimia Agrapidis, Jeroen van den Brink, Satoshi Nishimoto
We study isotropic antiferromagnetic Heisenberg chains coupled by antiferromagnetic Ising interaction as an effective spin model for the ytterbium aluminum perovskite YbAlO. Us…
Ground state and low-energy excitations of the Kitaev-Heisenberg ladder
Cliò Efthimia Agrapidis, Jeroen van den Brink, Satoshi Nishimoto
We study the ground state and low-lying excited states of the Kitaev-Heisenberg model on a ladder geometry using the density matrix renormalization group and Lanczos exact diagonal…
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…
