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…

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…
