Liquid-Liquid Phase Separation in a Minimal Explicit-Solvent Lattice Model Mimicking Protein Solutions
Siddhartha Roy, Rakesh S. Singh
Biomolecular condensates play essential roles in cellular processes, and recent efforts have focused on understanding their assembly and rational design principles. In this study,…
Compositional fluctuations and polymorph selection in crystallization of model soft colloids
Abhilasha Kumari, Gadha Ramesh, Debasish Koner +2
Understanding polymorph selection in atomic and molecular systems and its control through thermodynamic conditions and external factors (such as seed characteristics) is fundamenta…
Manifestations of the possible thermodynamic origin of water's anomalies in non-classical vapor nucleation at negative pressures
Yuvraj Singh, Mantu Santra, Rakesh S. Singh
Over the years, various scenarios -- such as the stability-limit conjecture (SLC), two critical point (TCP), critical point-free (CPF), and singularity-free (SF) -- have been propo…
Effects of quenched disorder on the kinetics and pathways of phase transition in a soft colloidal system
Gadha Ramesh, Mantu Santra, Rakesh S. Singh
Although impurities are unavoidable in real-world and experimental systems, most numerical studies on nucleation focus on pure (impurity-free) systems. As a result, the role of imp…
Anomalous Vapor and Ice Nucleation in Water at Negative Pressures: A Classical Density Functional Theory Study
Yuvraj Singh, Mantu Santra, Rakesh S. Singh
In contrast to the abundance of work on the anomalous behavior of water, the relationship between the water's thermodynamic anomalies and kinetics of phase transition from metastab…
Manifestations of the structural origin of supercooled water's anomalies in the heterogeneous relaxation on the potential energy landscape
Arijit Mondal, Gadha R., Rakesh S. Singh
Liquid water is well-known for its intriguing thermodynamic anomalies in the supercooled state. The phenomenological two-state models - based on the assumption of the existence of…
Polymorph selection during crystallization of a model colloidal fluid with a free energy landscape containing a metastable solid
Mantu Santra, Rakesh S. Singh, Biman Bagchi
The free energy landscape responsible for crystallization can be complex even for relatively simple systems like hard sphere and charged stabilized colloids. In this work, using ha…
Orientational order as the origin of the long-range hydrophobic effect
Saikat Banerjee, Rakesh S. Singh, Biman Bagchi
The long range attractive force between two hydrophobic surfaces immersed in water is observed to decrease exponentially with their separation -- this distance-dependence of effect…
Strongly first order melting of a two dimensional molecular solid
Rakesh S. Singh, Mantu Santra, Biman Bagchi
Melting and freezing transitions in two dimensional systems are known to show highly unusual characteristics. Most of the earlier studies considered atomic systems; the melting beh…
Interplay between the range of attractive potential and metastability in gas-liquid nucleation
Rakesh S. Singh, Mantu Santra, Biman Bagchi
We find an interesting interplay between the range of the attractive part of the interaction potential and the extent of metastability (as measured by supersaturation) in gas-liqui…
Propagating rotational jump events drive liquid-liquid transition in supercooled liquid water
Biman Jana, Rakesh Saran Singh, Biman Bagchi
We observe, at low temperature, the appearance of propagating events that originate from the inter-conversion between adjacent four and five coordinated water molecules in supercoo…
