Detecting spin fractionalization in a spinon Fermi surface spin liquid
Motivated by the recent proposal that several candidate materials such as ${\mathrm{YbMgGaO}}_{4}$ could be spinon Fermi surface spin liquids, we explore the experimental consequences of the external magnetic fields on this exotic state. Specifically, we focus on the weak field regime where the spin-liquid state is well preserved and the …
