Entropic bottlenecks to nematic ordering in an $R P^{2}$ apolar spin model

B. Kamala Latha, V. S. S. Sastry, S. R. Shenoy

The Lebwohl-Lasher model of uniaxial liquid crystals with (\textit{n} = 3, \textit{d} = 2) was reported earlier to undergo a crossover transition to a novel nematic phase at a temp…

Topological phase transitions in 2-dimensional bent-core liquid crystal models

B. Kamala Latha, Surajit Dhara, V. S. S. Sastry

Spontaneous onset of a low temperature topologically ordered phase in a 2-dimensional (2D) lattice model of uniaxial liquid crystal (LC) was debated extensively pointing to a suspe…

Topological Transition to a Critical Phase in a Two-dimensional 3-Vector Model with non-Abelian Fundamental Group: A Simulational Study

Kamala Latha. B, Sastry V. S. S

Two-dimensional 3-vector (\textit{d}=2, \textit{n}=3) lattice model with inversion site symmetry and fundamental group of its order-parameter space $Π_{1} (R) = Z_{2}$ , did…
