"Ultra-weak" First-Order Phase Transition in Biaxial Liquid Crystals
Soumyajit Pramanick, Mrinal Kanti Debnath, Nababrata Ghoshal +2
We report high-resolution Monte Carlo evidence characterizing the hierarchy of transition strengths in biaxial nematogens. By employing multiple histogram reweighting on large latt…
Phase diagram of a biaxial nematogenic lattice model: A Monte Carlo simulation study
Mrinal Kanti Debnath, Soumyajit Pramanick, Sudeshna DasGupta +1
The phase diagram for a lattice system of biaxial molecules possessing symmetry and interacting with Straley's quadrupolar pair potential in Sonnet-Virga-Durand parameteri…
A Molecular Field Approach to Pressure Induced Phase Transitions in Liquid Crystals : Smectic-Nematic transition
Sabana Shabnam, Sudeshna DasGupta, Nababrata Ghoshal +2
Since a rigorous microscopic treatment of a nematic fluid system based on a pairwise interaction potential is immensely complex we had introduced a simple mean field potential whic…
High accuracy Monte Carlo study of dispersion model of biaxial liquid crystals
Nababrata Ghoshal, Soumyajit Pramanick, Sudeshna DasGupta +1
We present a high accuracy Monte Carlo simulation study of the Isotropic - Nematic phase transition of a lattice dispersion model of biaxial liquid crystals. The NI coexistence cur…
The bend elastic constant in a mixture of (4,4')-n-octyl-cyanobiphenyl and biphenyl
Sudeshna DasGupta, Soumen Kumar Roy
The effect of a rigid, non-polar and nonmesogenic solute biphenyl ((C_{6}H_{5}-C_{6}H_{5})) on the divergence of the bend elastic constant K_{33} of (4,4^{\prime}) -n-octyl-cyanobi…
Effect of a rigid nonpolar solute on the splay, bend elastic constants and on rotational viscosity coefficient of 4-4^\prime -n-octyl-cyanobiphenyl
Sudeshna DasGupta, Pinku Chattopadhyay, Soumen Kumar Roy
The effect of a rigid nonpolar non-mesogenic solute, ``biphenyl'' which is (C_{6}H_{5}-C_{6}H_{5}), on the splay and bend elastic constants and on the rotational viscosity coeffici…
