Anomalous thermodynamics of a quantum spin system with large residual entropy
J. Richter, J. Schulenburg, D. V. Dmitriev +2
In contrast to strongly frustrated classical systems, their quantum counterparts typically have a non-degenerate ground state. A counterexample is the celebrated Heisenberg sawtoot…

Flat-band physics in the spin-1/2 sawtooth chain
Oleg Derzhko, Jürgen Schnack, D. V. Dmitriev +2
We consider the strongly anisotropic spin-1/2 model on the sawtooth-chain lattice with ferromagnetic longitudinal interaction and aniferromagnetic transversal int…
