Field-induced Bose-Einstein condensation and supersolid in the two-dimensional Kondo necklace

Abstract

Quantum magnets are a promising platform to aid in the search for a Bose-Einstein condensate and investigations into the underlying mechanisms of these materials are an active area of research. Here, the authors present a numerical study of the two-dimensional Kondo necklace model and consider the various phases which can occur under an applied magnetic field suggesting field-induced condensate phases may exist for the quantum magnet Ba2NiO2(AgSe)2.
