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…
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…
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…
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…
Connecting real glasses to mean-field models
Ujjwal Kumar Nandi, Walter Kob, Sarika Maitra Bhattacharyya
We propose a novel model for a glass-forming liquid which allows to switch in a continuous manner from a standard three-dimensional liquid to a fully connected mean-field model. Th…
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…
Composition dependence of the glass forming ability in binary mixtures: The role of demixing entropy
Ujjwal Kumar Nandi, Atreyee Banerjee, Suman Chakrabarty +1
We present a comparative study of the glass forming ability of binary systems with varying composition, where the systems have similar global crystalline structure (CsCl+fcc). Bias…
