Phys. Rev. B 71, 014417 (2005) [7 pages]Specific heat of the S=1/2 Heisenberg model on the kagome lattice: High-temperature series expansion analysisReceived 13 July 2004; published 13 January 2005 We compute specific heat of the antiferromagnetic spin-1/2 Heisenberg model on the kagome lattice. We use a recently introduced technique to analyze high-temperature series expansion based on the knowledge of high-temperature series expansions, the total entropy of the system and the low-temperature expected behavior of the specific heat, as well as the ground-state energy. In the case of the kagome-lattice antiferromagnet, this method predicts a low-temperature peak at T∕J≲0.1. © 2005 The American Physical Society URL:
