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…
Strange metal transport from coupling to fluctuating spins
Simone Fratini, Ivan Duchemin, Arnaud Ralko +1
Metals hosting strong electronic interactions, including high-temperature superconductors, behave in ways that do not conform to normal Fermi liquid theory. To pinpoint the microsc…
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…
Transient localization from the interaction with quantum bosons
H. Rammal, A. Ralko, S. Ciuchi +1
We carefully revisit the electron-boson scattering problem, going beyond popular semi-classical treatments. By providing numerically exact results valid at finite temperatures, we…
