Effect of Spherical Confinement on the 2-TIPS of Soft Repulsive Spherocylinders
Jaydeep Mandal, Chandan Dasgupta, Prabal K. Maiti
We studied the 2-Temperature induced phase separation (2-TIPS) in a system of soft repulsive sphe rocylinders (SRS), confined on the surface of a sphere. We used two different anch…
Motility destabilizes an absorbing-state flock
Narayan Dutt Sharma, Subroto Mukerjee, Chandan Dasgupta +1
Activity, when it takes the form of motility, is generally seen to promote order in many-body systems. Here we present a one-dimensional lattice model that, in the non-motile limit…
The Jammed Phase of Infinitely Persistent Active Matter
M. C. Gandikota, Rituparno Mandal, Pinaki Chaudhuri +2
We study an extreme active matter system, which is essentially a dense assembly of athermal, soft and infinitely persistent active particles. Using extensive numerical simulations…
Dynamics of self-organization in dense persistent active matter
Atharva Shukla, Chandan Dasgupta
We consider a two-dimensional athermal binary mixture of Lennard-Jones particles with persistent random active forces. The liquid phase of this system for active forces exceeding a…
Activity-driven sorting, approach to criticality and turbulent flows in dense persistent active fluids
Suman Dutta, Pinaki Chaudhuri, Madan Rao +1
We show that dense active fluids comprising interacting particles with persistent self-propulsion are driven to a non-equilibrium steady state consisting of co-moving particles wit…
Melting of rods on a sphere via an intermediate hexatic phase
Jaydeep Mandal, Chandan Dasgupta, Prabal K. Maiti
We have studied, using molecular dynamics simulations, the pressure-induced melting in a monolayer of soft repulsive spherocylinders whose centers of mass are constrained to move o…
Percolation in a three-dimensional non-symmetric multi-color loop model
Soumya Kanti Ganguly, Sumanta Mukherjee, Chandan Dasgupta
We conducted Monte Carlo simulations to analyze the percolation transition of a non-symmetric loop model on a regular three-dimensional lattice. We calculated the critical exponent…
Thermodynamics of multi-colored loop models in three dimensions
Soumya Kanti Ganguly, Sumanta Mukherjee, Chandan Dasgupta
We study order-disorder transitions in three-dimensional \textsl{multi-colored} loop models using Monte Carlo simulations. We show that the nature of the transition is intimately r…
Cooperative motion in equilibrium phases across two-dimension melting in pure and disordered systems
Saikat Dutta, Prashanti Jami, Pinaki Chaudhuri +2
We uncover the dynamics of particles with Gaussian core interactions across melting in pure and disordered two-dimensional (2D) systems. Intriguing signatures of cooperative motion…
Growing length and time scales in activity-mediated glassy dynamics in confluent cell monolayers
Souvik Sadhukhan, Chandan Dasgupta, Saroj Kumar Nandi
Activity-mediated unjamming of a confluent glassy system is crucial for several biological processes, such as embryogenesis and cancer metastasis. During these processes, the cells…
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…
Extreme active matter at high densities
Rituparno Mandal, Pranab Jyoti Bhuyan, Pinaki Chaudhuri +2
Extreme active matter, an assembly of self-propelled particles with large persistence time and high Péclet number, exhibits remarkable behaviour at high densities. As $τ_p\to…
Dynamics of Glass Forming Liquids with Randomly Pinned Particles
Saurish Chakrabarty, Smarajit Karmakar, Chandan Dasgupta
It is frequently assumed that in the limit of vanishing cooling rate, the glass transition phenomenon becomes a thermodynamic transition at a temperature . However, with any…
