Anomalous thermodynamics of a quantum spin system with large residual entropy
In contrast to strongly frustrated classical systems, their quantum counterparts typically have a non-degenerate ground state. A counterexample is the celebrated Heisenberg sawtooth spin chain with ferromagnetic zigzag bonds J_1 and competing antiferromagnetic basal bonds J_2. At a quantum phase tra...
