Hydrodynamics without a relaxation gap: memory effects, nonlocality, and superdiffusion
Lorenzo Gavassino, Sukanya Mitra, Rajeev Singh
By studying a simple model of relativistic particles propagating through a background medium with an energy-dependent relaxation time that is unbounded from above, we investigate h…
Poles from the conserved kinetic equation: The emerging gradient structure and causality riddle of relativistic hydrodynamics
Sukanya Mitra
In this work, the poles and the resulting dispersion spectra from the relativistic kinetic equation have been analyzed with the help of a proposed collision kernel that conserves b…
Relativistic Dispersion Spectra across Lorentz boosted frames: Spurious modes and the enigma of causality
Sayantani Bhattacharyya, Sukanya Mitra, Shuvayu Roy +1
The analysis of excitation spectra in gradient-expanded relativistic fluid theories frequently leads to pathologies under Lorentz boosts. However, extracting the dispersion modes i…
Necessary conditions for causality from linearized stability at ultra-high boosts
Shuvayu Roy, Sukanya Mitra, Rajeev Singh
In this work, we provide a novel method to constrain the causal parameter space of a relativistic hydrodynamic system exclusively from its linear stability analysis at non-zero mom…
On the Approach Towards Equilibrium Through Momentum-Dependent Relaxation:Insights from Evolution of the Moments in Kinetic Theory
Reghukrishnan Gangadharan, Sukanya Mitra, Victor Roy
We investigate the impact of momentum-dependent relaxation time approximation in the Boltzmann equation within the Bjorken flow framework by analyzing the moments of the single-par…
Transport coefficients of hot and dense matter in relativistic heavy-ion collisions
Sukanya Mitra
The transport coefficients are known as the measure of system interactions, as well as the dynamical input of the hydrodynamic evolution equations of an expanding system created in…
