Low-temperature magnetic excitations in a 3D S=1/2 bcc quantum spin-liquid candidate

Abstract: A quantum spin-liquid (QSL) state is a highly correlated and long-range entangled state of matter, which evades any thermodynamic phase-transition and remains dynamically disordered as a result of quantum fluctuations. QSL state in 1D is well established, but in a sense much restricted compared to all the varieties of QSL predicted for 2D and 3D. Rare-earth based pyrochlore and hyperkagome materials have been extensively studied since they can host very exotic ground-states stabilized by anisotropic interactions, but identifying the true key ingredients of their low-T physics may be cumbersome. Here, we propose to investigate a more simple (3d), copper-based material that we have recently synthesized as single crystals. and identified as a QSL candidate. We now wish to identify the nature of its low energy excitation using inelastic neutron scattering.
