"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…
