Novel Universality Classes in Ferroelectric Liquid Crystals
Amit K Chattopadhyay, Prabir K Mukherjee
Starting from a Langevin formulation of a thermally perturbed nonlinear elastic model of the ferroelectric smectic-C (SmC) liquid crystals in the presence of an electric f…
Effect of magnetic nanoparticles on the nematic-smectic-A phase transition
Prabir K Mukherjee, Amit K Chattopadhyay
Recent experiments on mixed liquid crystals have highlighted the hugely significant role of ferromagnetic nanoparticle impurities in defining the nematic-smectic-A phase transition…
Double diffusivity model under stochastic forcing
Amit K Chattopadhyay, Elias C Aifantis
The "double diffusivity" model was proposed in the late 1970s, and reworked in the early 1980s, as a continuum counterpart to existing discrete models of diffusion corresponding to…
Dynamics of cholesteric liquid crystals in the presence of random magnetic fields
Amit K. Chattopadhyay, Prabir K. Mukherjee
Based on dynamic renormalization group techniques, this letter analyzes the effects of external stochastic perturbations on the dynamical properties of cholesteric liquid crystals,…
Dynamics of Pulsed Flow in an Elastic Tube
Amit K. Chattopadhyay, Shreekantha Sil
Internal haemorrhage, often leading to cardio-vascular arrest happens to be one of the prime sources of high fatality rates in mammals. We propose a simplistic model of fluid flow…
Dynamics of linear polymers in random media
Bikas K. Chakrabarti, Amit K. Chattopadhyay, Amit Dutta
We study phenomenological scaling theories of the polymer dynamics in random media, employing the existing scaling theories of polymer chains and the percolation statistics. We inv…
