Cosmological evolution with quadratic gravity and nonideal fluids
Saikat Chakraborty, Daniele Gregoris
Some cosmological models based on the gravitational theory , and on fluids obeying to the equations of state of Redlich-Kwong, Berthelot, and Dieterici are proposed…
A model independent approach to the study of cosmologies with expansion histories close to CDM
Saikat Chakraborty, Kelly MacDevette, Peter Dunsby
We propose a new framework for studying the cosmology of gravity which completely avoids using the reconstruction programme. This allows us to easily obtain a qualitative fe…
Relaxation in a Phase-separating Two-dimensional Active Matter System with Alignment Interaction
Saikat Chakraborty, Subir K. Das
Via computer simulations we study kinetics of pattern formation in a two-dimensional active matter system. Self-propulsion in our model is incorporated via the Vicsek-like activity…
Initial Correlation Dependence of Aging in Phase Separating Solid Binary Mixtures and Ordering Ferromagnets
Subir K. Das, Koyel Das, Nalina Vadakkayil +2
Following quenches of initial configurations having long range spatial correlations, prepared at the demixing critical point, to points inside the miscibility gap, we study aging p…
Dynamical equivalence of gravity in Jordan and Einstein frames
Saikat Chakraborty, Sanchari Pal, Alberto Saa
We investigate the dynamics of gravity in Jordan and Einstein frames. First, we perform a phase-space singularities analysis in both frames. We show that, typically, anisotr…
Finite-Size Scaling Study of Aging during Coarsening in Non-Conserved Ising Model: The case of zero temperature quench
Nalina Vadakkayil, Saikat Chakraborty, Subir K. Das
Following quenches from random initial configurations to zero temperature, we study aging during evolution of the ferromagnetic (nonconserved) Ising model towards equilibrium, via…
