Flow-induced currents in nanotubes: a Brownian dynamics approach
Moumita Das, Sriram Ramaswamy, A. K. Sood +1
Motivated by recent experiments [Science {\bf 299}, 1042 (2003)] reporting that carbon nanotubes immersed in a flowing fluid displayed an electric current and voltage, we numerical…
Nonequilibrium steady states of the isotropic classical magnet
Jayajit Das, Madan Rao, Sriram Ramaswamy
We drive a d-dimensional Heisenberg magnet using a spatially anisotropic current of mobile particles or heat. The continuum Langevin equation is analyzed using a dynamical renormal…
The segregation instability of a sheared suspension film
Rama Govindarajan, Prabhu R. Nott, Sriram Ramaswamy
Starting from the equations of Stokes flow and the mass conservation of particles as determined by shear-induced diffusion, we derive the coupled equations for the dynamics of part…
Collective stochastic resonance in shear-induced melting of sliding bilayers
Moumita Das, G. Ananthakrishna, Sriram Ramaswamy
The far-from-equilibrium dynamics of two crystalline two-dimensional monolayers driven past each other is studied using Brownian dynamics simulations. While at very high and low dr…
A ratchet for heat transport between identical reservoirs
Souvik Das, Onuttom Narayan, Sriram Ramaswamy
A one-dimensional periodic array of elastically colliding hard points, with a non-centrosymmetric unit cell, connected at its two ends to {\em identical but non-thermal} energy res…
Phase Diagram of a Two-Species Lattice Model with a Linear Instability
Sriram Ramaswamy, Mustansir Barma, Dibyendu Das +1
We review recent progress in understanding the full phase diagram of a one-dimensional, driven, two-species lattice model [Lahiri and Ramaswamy, PRL 79 (1997) 1150] in which the mo…
