| Summary: | The hard-core lattice gas on a triangular lattice with up to thirdneighbour exclusion has been simulated by the transfer matrix
method. To calculate the transfer matrix a special algorithm for
generating rings is used. The algorithm is based on the selection
of admissible states of rings directly in the process of their
construction. This approach allows us to increase the available
sizes of rings. Isotherms have been constructed for all three
models. For the first and second models, the previously obtained
results are reproduced. For the third model, it is found that there
is a first-order phase transition and the unit cell size of the ordered
phase is equal to seven. |
