Título: Comportamento termodinâmico de varetas polidispersas na rede quadrada

Apresentador: Jurgen Stilck (UFF).

Resumo: We study the grand-canonical solution of a system of hard
polydispersed rods placed on the square lattice using transfer matrix and
finite size scaling calculations. We determine the critical line
separating an isotropic from a nematic phase. No second transition to a
disordered phase is found at high density, contrary to what is observed in
the monodispersed case. The estimates of critical exponents and the central
charge on the critical line are consistent with the Ising universality class..
