No quasi-long-range order in the two-dimensional liquid crystal
Ricardo Paredes, Ana-Isabel Fariñas-Sánchez, Robert Botet
Systems with global symmetry group O(2) experience topological transition in the 2-dimensional space. But there is controversy about such a transition for systems with global symme…
Topological transition in a two-dimensional model of liquid crystal
Ana Fariñas-Sanchez, Ricardo Paredes, Bertrand Berche
Simulations of nematic-isotropic transition of liquid crystals in two dimensions are performed using an O(2) vector model characterised by non linear nearest neighbour spin interac…
Correlations in the low-temperature phase of the two-dimensional XY model
B. Berche, A. Farinas Sanchez, R. Paredes
Monte Carlo simulations of the two-dimensional XY model are performed in a square geometry with fixed boundary conditions. Using a conformal mapping it is very easy to deduce the e…
