A self-consistent quasilinear theory for collisionless relaxation to universal quasi-steady state attractors in cold dark matter halos
Uddipan Banik, Amitava Bhattacharjee
Collisionless self-gravitating systems, e.g., cold dark matter halos, harbor universal density profiles despite the intricate non-linear physics of hierarchical structure formation…
Universal non-thermal power-law distribution functions from the self-consistent evolution of collisionless electrostatic plasmas
Uddipan Banik, Amitava Bhattacharjee, Wrick Sengupta
Distribution functions of collisionless systems are known to show non-thermal power law tails. Interestingly, collisionless plasmas in various physical scenarios, (e.g., the ion po…
Pushing the Frontiers of Non-equilibrium Dynamics of Collisionless and Weakly Collisional Self-gravitating Systems
Uddipan Banik
In the standard cosmological paradigm, structure formation occurs via gravitational encounters and mergers between galaxies and dark matter halos. These collisionless self-gravitat…
Relaxation of weakly collisional plasma: continuous spectra, discrete eigenmodes, and the decay of echoes
Uddipan Banik, Amitava Bhattacharjee
The relaxation of a weakly collisional plasma, which is of fundamental interest to laboratory and astrophysical plasmas, can be described by the Boltzmann-Poisson equations with th…
