Chiral bosonic mean-field Ansatz and spin dynamics in spin-1 Kitaev magnets
Daiki Sasamoto, Arnaud Ralko, Jaime Merino +1
The Kitaev model is a paradigmatic system for realizing quantum spin liquids, but its higher-spin extensions are not exactly solvable, and their spin dynamics is less well understo…
Order-by-disorder from Schwinger bosons in a frustrated honeycomb ferromagnet
Arnaud Ralko, Jaime Merino
The cobalt-based honeycomb magnet BaCo(AsO) (BCAO) has recently emerged as a promising platform for frustrated magnetism beyond conventional paradigms. Neutron-scatteri…
Even-odd effect in multilayer Kitaev honeycomb magnets
Jaime Merino, Arnaud Ralko
Motivated by the three-dimensional structure of Kitaev materials we explore multilayer Kitaev models. The magnetic properties of a multilayer of an arbitrary number of Kitaev honey…
Chiral bosonic quantum spin liquid in the integer-spin Heisenberg-Kitaev model
Arnaud Ralko, Jaime Merino
Motivated by the possibility of finding a bosonic quantum spin liquid in the integer spin- Heisenberg-Kitaev model on the honeycomb lattice, we derive a Schwinger boson mean fie…
