SSD-based finite-size calculations show shoulder or double-peak specific heat in triangular and kagome antiferromagnets plus strong low-T susceptibility enhancement in kagome, indicating magnetic states dominate its excitations below 0.5J unlike the triangular case.
Advocates treating numerical, analytical, and experimental efforts as equal contributors to progress in quantum magnetism instead of viewing them as supporting tools.
