Claims
The Ising models can be strain-tuned into and out of classical spin-liquid phases, and we show that η can become arbitrarily large at low temperature T near the point of maximal frustration, a universal hallmark of an extensive ground-state entropy.
The assumption that uniaxial strain acts primarily as a tunable anisotropy parameter that drives the system through the maximally frustrated point without introducing additional interactions or disorder not captured by the minimal lattice models (abstract, paragraph on model definitions).
The elastic Grüneisen ratio becomes arbitrarily large at low T near maximal frustration in Ising models, signaling extensive ground-state entropy, while Heisenberg models show phase transitions dominating the low-T response.
