Ground state entropy of the Potts antiferromagnet on homeomorphic expansions of kagomé lattice strips.

چکیده
We present exact calculations of the chromatic polynomial and resultant ground state entropy of the q-state Potts antiferromagnet on lattice strips that are homeomorphic expansions of a strip of the kagomé lattice. The dependence of the ground state entropy on the form of homeomorphic expansion is elucidated.

Ground State Entropy of the Potts Antiferromagnet on Strips of the Square Lattice
We present exact solutions for the zero-temperature partition function (chromatic polynomial P ) and the ground state degeneracy per site W (= exponent of the ground-state entropy) for the q-state Potts antiferromagnet on strips of the square lattice of width Ly vertices and arbitrarily great length Lx vertices. The specific solutions are for (a) Ly = 4, (FBCy, PBCx) (cyclic); (b) Ly = 4, (FBCy...

We present exact calculations of the zero-temperature partition function (chromatic polynomial) and W(q), the exponent of the ground-state entropy, for the q-state Potts antiferromagnet with next-nearest-neighbor spin-spin couplings on square lattice strips, of width L(y)=3 and L(y)=4 vertices and arbitrarily great length Lx vertices, with both free and periodic boundary conditions. The resulta...
متن کاملAntiferromagnet on the Honeycomb Lattice
We study the q-state Potts antiferromagnet with q = 3 on the honeycomb lattice. Using an analytic argument together with a Monte Carlo simulation, we conclude that this model is disordered for all T ≥ 0. We also calculate the ground state entropy to be S0/kB = 0.507(10) and discuss this result. ∗email: [email protected] ∗∗email: [email protected] The effect of ground s...

We present exact calculations of the zero-temperature partition function (chromatic polynomial) P for the q-state Potts antiferromagnet on triangular lattice strips of arbitrarily great length Lx vertices and of width Ly = 3 vertices and, in the Lx → ∞ limit, the exponent of the ground-state entropy, W = e0B . The strips considered, with their boundary conditions (BC) are (a) (FBCy, PBCx) = cyc...
متن کاملLower bounds on the ground-state entropy of the Potts antiferromagnet on slabs of the simple cubic lattice.
We calculate rigorous lower bounds for the ground-state degeneracy per site, W, of the q-state Potts antiferromagnet on slabs of the simple cubic lattice that are infinite in two directions and finite in the third and that thus interpolate between the square (sq) and simple cubic (sc) lattices. We give a comparison with large-q series expansions for the sq and sc lattices and also present numer...
