  • The large D black hole membrane paradigm at first subleading order 
    Dandekar, Yogesh; DE, ANANDITA; Mazumdar, Subhajit; Minwalla, Shiraz; Saha, Arunabha (Springer Nature, 2016-12)
    In the large D limit, and under certain circumstances, it has recently been demonstrated that black hole dynamics in asymptotically flat spacetime reduces to the dynamics of a non gravitational membrane propagating in flat ...
  • Effects of initial-state dynamics on collective flow within a coupled transport and viscous hydrodynamic approach 
    Chattopadhyay, Chandrodoy; BHALERAO, RAJEEV S.; Ollitrault, Jean-Yves; Pal, Subrata (American Physical Society, 2018-03)
    We evaluate the effects of preequilibrium dynamics on observables in ultrarelativistic heavy-ion collisions. We simulate the initial nonequilibrium phase within a multiphase transport (AMPT) model, while the subsequent ...
  • Density relaxation in conserved Manna sandpiles 
    Tapader, Dhiraj; Pradhan, Punyabrata; DHAR, DEEPAK (American Physical Society, 2021-03)
    We study relaxation of long-wavelength density perturbations in a one-dimensional conserved Manna sand-pile. Far from criticality where correlation length xi is finite, relaxation of density profiles having wave numbers k ...
  • GPU-based Multiscale Simulation to Model Active Matter Hydrodynamics in Fluid Medium 
    T N, SUHAL SIVA RATAN (2023-05)
    Active matter systems are soft matter systems characterized by many interacting active particles, such as bacterial suspensions or Janus particles. While dry active matter systems have been studied extensively, hydrodynamic ...
  • The dynamical tides of spinning Newtonian stars 
    Pnigouras, P.; Gittins, F.; NANDA, A.; Andersson, N.; Jones, D. I. (The Royal Astronomical Society, 2024-01)
    We carefully develop the framework required to model the dynamical tidal response of a spinning neutron star in an inspiralling binary system, in the context of Newtonian gravity, making sure to include all relevant details ...
  • Anomalous transport in long-ranged open quantum systems 
    DHAWAN, ABHINAV; GANGULY, KATHA; Kulkarni, Manas; AGARWALLA, BIJAY KUMAR (American Physical Society, 2024-08)
    We consider a one-dimensional fermionic lattice system with long-ranged power-law decaying hopping with exponent 𝛼. The system is further subjected to dephasing noise in the bulk. We investigate two variants of the problem: ...
