Specific heat of the S = 12 Heisenberg model on the kagome lattice : High - temperature series expansion analysis
نویسنده
چکیده
We compute specific heat of the antiferromagnetic spin2 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.

Magnetic susceptibility and specific heat of the spin - 12 Heisenberg model on the kagome lattice and experimental data on
We compute the magnetic susceptibility and specific heat of the spin1 2 Heisenberg model on the kagome lattice with high-temperature expansions and exact diagonalizations. We compare the results with the experimental data on ZnCu3(OH)6Cl2 obtained by Helton et al. [Phys. Rev. Lett. 98, 107204 (2007)]. Down to kBT/J ' 0.2, our calculations reproduce accurately the experimental susceptibility, wi...
متن کاملSpecific Heat of discrete systems and high - temperature series : new interpolation scheme and examples on spin - 1 / 2 Heisenberg models
We present a model for evaluating the specific heat of lattice spin systems. It is 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. By the choice of an appropriate variable (entropy as a function of energy), a stable interpolation scheme between low and...
متن کاملAlgebraic vortex liquid theory of a quantum antiferromagnet on the kagome lattice
There is growing evidence from both experiment and numerical studies that low half-odd integer quantum spins on a kagome lattice with predominant antiferromagnetic near-neighbor interactions do not order magnetically or break lattice symmetries even at temperatures much lower than the exchange interaction strength. Moreover, there appears to be a plethora of low-energy excitations, predominantl...
متن کاملDamage spreading in two dimensional geometrically frustrated lattices: the triangular and kagome anisotropic Heisenberg model
The technique of damage spreading is used to study the phase diagram of the easy axis anisotropic Heisenberg antiferromagnet on two geometrically frustrated lattices. The triangular and kagome systems are built up from triangular units that either share edges or corners respectively. The triangular lattice undergoes two sequential Kosterlitz-Thouless transitions while the kagome lattice undergo...

The Ising model is one of the simplest models describing the interacting particles. In this work, we calculate the high temperature series expansions of zero field susceptibility of ising model with ferromagnetic, antiferromagnetic and one antiferromagnetic interactions on two dimensional kagome lattice.
