Growth of Structural Lengthscale in Kob Andersen Binary Mixtures: Role of medium range order
Sanket Kumawat, Mohit Sharma, Ujjwal Kumar Nandi +2
A central and extensively debated question in glass physics concerns whether a single, growing lengthscale fundamentally controls glassy dynamics, particularly in systems lacking o…
Structure-Dynamics Correlation and Its Link to Fragility and Dynamic Heterogeneity
Mohit Sharma, Srikanth Sastry, Sarika Maitra Bhattacharyya
Understanding the connection between structure, dynamics, and fragility, the rate at which the relaxation time grows with decreasing temperature, is central to unravelling the glas…
Dynamic signature of the thermodynamic transition in a novel mean field system
Ehtesham Anwar, Ujjwal Kumar Nandi, Palak Patel +2
Understanding the connection between thermodynamics and dynamics in glass-forming liquids remains a central challenge in condensed matter physics. In this study, we investigate a n…
Exploring the soft pinning effect in the dynamics and the structure dynamics correlation in multicomponent supercooled liquids
Ehtesham Anwar, Palak Patel, Mohit Sharma +1
We study multicomponent liquids by increasing the mass of of the particles in a binary Kob-Andersen model. We find that the heavy particles have dual effects on the lighter…
Effect of the presence of pinned particles on the structural parameters of a liquid and correlation between structure and dynamics at the local level
Palak Patel, Sarika Maitra Bhattacharyya
Pinning particles at the equilibrium configuration of the liquid is expected not to affect the structure and any property that depends on the structure while slowing down the dynam…
A comparative study of the correlation between the structure and the dynamics for systems interacting via attractive and repulsive potentials
Mohit Sharma, Manoj Kumar Nandi, Sarika Maitra Bhattacharyya
We present the study of the structure-dynamics correlation for systems interacting via attractive Lennard- Jones and its repulsive counterpart, the WCA potentials. The structural o…
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…
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…
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…
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…
Fickian yet non-Gaussian behaviour: A dominant role of the intermittent dynamics
Sayantan Acharya, Ujjwal Kumar Nandi, Sarika Maitra Bhattacharyya
We present a study of the dynamics of small solute particles in a solvent medium where the solute is much smaller in size, mimicking the diffusion of small particles in crowded env…
