A comparison of two constructions for dynamical corrections to Wald entropy
Sayantani Bhattacharyya, Parthajit Biswas, Nilay Kundu
In this work, we analyze the differences and similarities between two recent constructions, which are distinct in their methodologies for extending the Wald entropy of stationary 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…
Relativistic fluid dynamics in a 'hydro' frame
Sayantani Bhattacharyya, Sukanya Mitra, Shuvayu Roy +1
In this letter, we investigate how field redefinition influences the spectrum of linearized perturbations in relativistic fluid dynamics. We show that the hydrodynamic modes do not…
Field redefinition and its impact in relativistic hydrodynamics
Sayantani Bhattacharyya, Sukanya Mitra, Shuvayu Roy +1
In this paper, we explore the impact of field redefinition on the spectrum of linearized perturbations in relativistic hydrodynamics. We observe that the spectrum of hydrodynamics…
Causality and stability in relativistic hydrodynamic theory -- a choice to be endured
Sayantani Bhattacharyya, Sukanya Mitra, Shuvayu Roy
In this work, it has been indicated that the key features requisite for preserving causality and stability of the popularly existing relativistic hydrodynamic theories, can be tran…
A classical Bousso bound for higher derivative corrections to general relativity
Sayantani Bhattacharyya, Parthajit Biswas, Nilay Kundu
Focussing on theories for which the higher derivative terms are considered as small corrections in the Lagrangian to Einstein's two-derivative theory of general relativity (GR), we…
