Query: Finite-temperature crossover phenomenon in the $S=1/2$ antiferromagnetic
  Heisenberg model on the kagome lattice   Thermal properties of the $S=1/2$ kagome Heisenberg antiferromagnet at low
temperatures are investigated by means of the Hams-de Raedt method for clusters
of up to 36 sites possessing a full symmetry of the lattice. The specific heat
exhibits, in addition to the double peaks, the third and the forth peaks at
lower temperatures. With decreasing the temperature, the type of the magnetic
short-range order (SRO) changes around the third-peak temperature from the
$\sqrt{3} \times \sqrt{3}$ to the $q$=0 states, suggesting that the third peak
of the specific heat is associated with a crossover phenomenon between the
spin-liquid states with distinct magnetic SRO. Experimental implications are
discussed.
