Motility driven glassy dynamics in confluent epithelial monolayers
Souvik Sadhukhan, Manoj Kumar Nandi, Satyam Pandey +4
As wounds heal, embryos develop, cancer spreads, or asthma progresses, the cellular monolayer undergoes glass transition between solid-like jammed and fluid-like flowing states. Du…
Thermodynamics and its correlation with dynamics in a mean-field model and pinned systems: A comparative study using two different methods of entropy calculation
Ujjwal Kumar Nandi, Palak Patel, Mohd Moid +6
Recently, some of us developed a novel model glass-forming liquid with k extra interactions with pseudo neighbours to each liquid particle over and above the regular interactions w…
Identifying structural signature of dynamical heterogeneity via the local softness parameter
Mohit Sharma, Manoj Kumar Nandi, Sarika Maitra Bhattacharyya
In a recent study by some of us, we have proposed a new measure of the structure of a liquid, the softness of the mean-field caging potential, and shown that it can describe the te…
Effective structure of a system with continuous polydispersity
Palak Patel, Manoj Kumar Nandi, Ujjwal Kumar Nandi +1
In a system of N particles, with continuous size polydispersity there exists N(N-1) number of partial structure factors making it analytically less tractable. A common practice is…
A Microscopic Theory of Softness in Supercooled Liquids
Manoj Kumar Nandi, Sarika Maitra Bhattacharyya
We introduce a new measure of the structure of a liquid which is the softness of the mean-field potential developed by us earlier. We find that this softness is sensitive to small…
Continuous time random walk concepts applied to extended mode coupling theory: A study of the Stokes-Einstein breakdown
Manoj Kumar Nandi, Sarika Maitra Bhattacharyya
In an attempt to extend the mode coupling theory (MCT) to lower temperatures, an Unified theory was proposed which within the MCT framework incorporated the activated dynamics via…
A Comparative Study of a Class of Mean Field Theories of the Glass Transition
Indranil Saha, Manoj Kumar Nandi, Chandan Dasgupta +1
In a recently developed microscopic mean field theory, we have shown that the dynamics of a system, when described only in terms of its pair structure, can predict the correct dyna…
Analysis of the anomalous mean field like properties of Gaussian core model in terms of entropy
Manoj Kumar Nandi, Sarika Maitra Bhattacharyya
Studies of the Gaussian core model (GCM) have shown that it behaves like a mean field model and the properties are quite different from standard glass former. In this work we inves…
The role of pair correlation function in the dynamical transition predicted by the mode coupling theory
Manoj Kumar Nandi, Atreyee Banerjee, Chandan Dasgupta +1
In a recent study we have found that for a large number of systems the configuration entropy at pair level, , which is primarily determined by the structural information, v…
Validity of the Rosenfeld relationship: A comparative study of the network forming NTW model and other simple liquids
Atreyee Banerjee, Manoj Kumar Nandi, Sarika Maitra Bhattacharyya
In this paper we explore the validity of the Rosenfeld and the Dzugutov relation for the Lennard-Jones (LJ) system, its repulsive counterpart, the WCA system and a network forming…
Determination of onset temperature from the entropy for fragile to strong liquids
Atreyee Banerjee, Manoj Kumar Nandi, Srikanth Sastry +1
In this paper we establish a connection between the onset temperature of glassy dynamics with the change in the entropy for a wide range of model systems. We identify the crossing…
Effect of total and pair configurational entropy in determining dynamics of supercooled liquids over a range of densities
Atreyee Banerjee, Manoj Kumar Nandi, Srikanth Sastry +1
In this paper, we present a study of supercooled liquids interacting with the Lennard Jones (LJ) potential and the corresponding purely repulsive (Weeks-Chandler-Andersen or WCA) p…
Unraveling the success and failure of mode coupling theory from consideration of entropy
Manoj Kumar Nandi, Atreyee Banerjee, Shiladitya Sengupta +2
We analyze the dynamics of model supercooled liquids in a temperature regime where predictions of mode coupling theory (MCT) are known to be valid qualitatively. In this regime, th…
Non-monotonic Size Dependence of Diffusion and Levitation Effect: A Mode Coupling Theory Analysis
Manoj Kumar Nandi, Atreyee Banerjee, Sarika Maitra Bhattacharyya
We present a study of diffusion of small tagged particles in a solvent, using mode coupling theory (MCT) analysis and computer simulations. The study is carried out for various int…
