Magnetic Field Induced Quantum Phases in a Tensor Network Study of Kitaev Magnets

In a recent published article in Nature Communication, a team of researchers from University of Tokyo and University of Toronto led by Prof Yong Baek Kim reported the discovery of a novel quantum ground state in theoretical models designed for the so-called Kitaev magnets in external magnetic field.

They used the tensor-network approach, a quantum-information inspired method, to demonstrate the existence of the nematic paramagnet. Such novel ground states break the lattice rotational symmetry spontaneously and may be relevant to a series of remarkable recent experiments done on this class of materials.
