Author(s): Bishnu P. Belbase, Arjun Unnikrishnan, Shi Feng, Eun Sang Choi, Johannes Knolle, and Arnab Banerjee TlYbSe 2 is a triangular-lattice frustrated magnet that exhibits no long-range order down to 30 mK, indicating a ground state that could be a quantum spin liquid. Heat capacity shows a peculiar linear trend that can be reconciled with theory based on U (1) gauge flux excitations interacting with emergent fermions, providing compelling evidence for a U (1) quantum spin liquid state.
