Derivation of an equation of pair correlation function from BBGKY hierarchy in a weakly coupled self gravitating system
Anirban Bose
An equation of pair correlation function has been derived from the first two members of BBGKY hierarchy in a weakly coupled inhomogeneous self gravitating system in quasi thermal e…
Determination of pair correlation function in a weakly correlated weakly inhomogeneous plasma
Anirban Bose
In a weakly correlated inhomogeneous plasma an equation of pair correlation function is obtained utilizing the Bogoliubov-Born-Green-Kirkwood-Yvon (BBGKY) hierarchy of equations. I…
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…
Collapse of ferromagnetism with Ti doping in SmSrMnO: A combined experimental and theoretical study
P. Sarkar, N. Khan, K. Pradhan +1
We have investigated the effect of Ti doping on the transport properties coupled with the magnetic ones in SmSrMnTiO (). The pa…
Continuously Varying Critical Exponents Beyond Weak Universality
N. Khan, P. Sarkar, A. Midya +2
Renormalization group theory does not restrict the from of continuous variation of critical exponents which occurs in presence of a marginal operator. However, the continuous varia…
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,…
