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…
Role of quantum fluctuations on spin liquids and ordered phases in the Heisenberg model on the honeycomb lattice
J. Merino, A. Ralko
Motivated by the rich physics of honeycomb magnetic materials, we obtain the phase diagram and analyze magnetic properties of the spin-1/2 and spin-1 J1-J2-J3 Heisenberg model on t…
