Geometry-induced flocking and topological sound on a defect-free curved surface
Devendra Saini, Atanu Bhatta, Pritha Dolai
We study an ordered polar active flock on a torus and show that topological sound persists on a compact curved surface without topological defects or physical boundaries. Using the…
Shape Evolution and Dynamics of Deformable Ring
Arun Kumar, Partha Sarathi Mondal, Pritha Dolai +1
We numerically investigate the dynamics of a deformable closed ring filled with active particles. The ring is modeled as a flexible boundary made up of passive beads interacting wi…
Boundary layers, transport and universal distribution in boundary driven active systems
Pritha Dolai, Arghya Das
We discuss analytical results for a run-and-tumble particle (RTP) in one dimension in presence of boundary reservoirs. It exhibits `kinetic boundary layers', nonmonotonous distribu…
Shape-dependent motility of polar inclusions in active baths
Pritha Dolai, Aditya Singh Rajput, K. Vijay Kumar
Collections of persistently moving active particles are an example of a nonequilibrium heat bath. One way to study the nature of nonequilibrium fluctuations in such systems is to f…
Specific heat of a driven lattice gas
Pritha Dolai, Christian Maes
Calorimetry for equilibrium systems aims to determine the available microscopic occupation and distribution of energy levels by measuring thermal response. Nonequilibrium versions…
Calorimetry for active systems
Pritha Dolai, Christian Maes, Karel Netočný
We provide the theoretical basis of calorimetry for a class of active particles subject to thermal noise. Simulating AC-calorimetry, we numerically evaluate the heat capacity of ru…
Inducing a bound state between active particles
Pritha Dolai, Simon Krekels, Christian Maes
We show that two active particles can form a bound state by coupling to a driven nonequilibrium environment. We specifically investigate the case of two mutually noninteracting run…
Harnessing confinement and driving to tune active particle dynamics
Aniruddh Murali, Pritha Dolai, Ashwini Krishna +2
A distinguishing feature of active particles is the nature of the non-equilibrium noise driving their dynamics. Control of these noise properties is, therefore, of both fundamental…
Kardar-Parisi-Zhang universality in two-component driven diffusive models: Symmetry and renormalization group perspectives
Pritha Dolai, Aditi Simha, Abhik Basu
We elucidate the universal spatio-temporal scaling properties of the time-dependent correlation functions in a class of two-component one-dimensional (1D) driven diffusive system t…
Universal scaling in active single-file dynamics
Pritha Dolai, Arghya Das, Anupam Kundu +3
We study the single-file dynamics of three classes of active particles: run-and-tumble particles, active Brownian particles and active Ornstein-Uhlenbeck particles. At high activit…
Phase separation in binary mixtures of active and passive particles
Pritha Dolai, Aditi Simha, Shradha Mishra
We study binary mixtures of small active and big passive athermal particles interacting via soft repulsive forces on a frictional substrate. Athermal self propelled particles are k…
Universal spatio-temporal scaling of distortions in a drifting lattice
Pritha Dolai, Abhik Basu, Aditi Simha
We study the dynamical response to small distortions of a lattice about its uniform state, drifting through a dissipative medium due to an external force, and show, analytically an…
Large deviation statistics of non-equilibrium fluctuations in a sheared model-fluid
Pritha Dolai, Aditi Simha
We analyse the statistics of the shear stress in a one dimensional \emph{model fluid}, that exhibits a rich phase behaviour akin to real complex fluids under shear. We show that th…
