Improved analysis of rare earth magnetic superconductors
Preeti Suman Dash, Salila Das, Prabir K. Mukherjee
We present an improved analysis of the phase transitions in rare earth superconductor using Ginzburg-Landau theory. Our work is based on the systematic study of critical field and…
Role of external and internal perturbations on ferromagnetic phase transitions in manganites: Existence of tricritical points
Prabir K Mukherjee, Prosenjit Sarkar, Amit K Chattopadhyay
A phenomenological mean-field theory is presented to describe the role of external magnetic field, pressure and chemical substitution on the nature of ferromagnetic (FM) to paramag…
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…
