This field induced phase appears between the low field zig-zag magnetic order and the high field polarized state. Motivated by this experiment, we study possible field induced quantum phases in theoretical models of the Kitaev magnets, using the two dimensional tensor network approach or infinite tensor product states. We find various quantum ground states in addition to the chiral Kitaev spin liquid occupying a small area in the phase diagram. They form a band of emergent quantum phases in an intermediate window of external magnetic fields, somewhat reminiscent of the experiment. We discuss the implications of these results in view of the experiment and previous theoretical studies.Nature communicationsMagnetic field induced quantum phases in a tensor network study of Kitaev magnets.PMC7118087JPMJPR15NFKAKENHI (19H01809)KAKENHI 19K03740Kawashima NChern LELee HYKaneko RYamaji YOkubo TKim YB45falseMagnetic field induced quantum phases in a tensor network study of Kitaev magnets.Recent discovery of the half quantized thermal Hall conductivity in [Formula: see text]-RuCl[Formula: see text], a candidate material for the Kitaev spin liquid, suggests the presence of a highly entangled quantum state in external magnetic fields.
