Phase transition in liquid crystal elastomer - a Monte Carlo study employing non-Boltzmann sampling
We investigate Isotropic - Nematic transition in liquid crystal elastomers employing non-Boltzmann Monte Carlo techniques. We consider a lattice model of a liquid elastomer and Selinger-Jeon-Ratna Hamiltonian which accounts for homogeneous/inhomogeneous interactions among liquid crystalline units, i...

| description | We investigate Isotropic - Nematic transition in liquid crystal elastomers employing non-Boltzmann Monte Carlo techniques. We consider a lattice model of a liquid elastomer and Selinger-Jeon-Ratna Hamiltonian which accounts for homogeneous/inhomogeneous interactions among liquid crystalline units, interaction of local nematics with global strain, and with inhomogeneous external fields and stress. We find that when the local director is coupled strongly to the global strain the transition is strongly first order; the transition softens when the coupling becomes weaker. Also the transition temperature decreases with decrease of coupling strength. Besides we find that the nematic order scales nonlinearly with global strain especially for strong coupling and at low temperatures. |
