Near-Light-Cone Nonhydrodynamic Structure from Boosted Hydrodynamics
Navid Abbasi, Jewel Kumar Ghosh, Dirk H. Rischke
Hydrodynamics provides a universal description of many-body systems at long wavelengths. Its long-lived collective excitations, known as hydrodynamic modes, admit long-wavelength e…

Hydrostatic equilibrium in multi-Weyl semimetals
Jewel Kumar Ghosh, Francisco Peña-BenÃtez, Patricio Salgado-Rebolledo
We study the hydrostatic equilibrium of multi-Weyl semimetals, a class of systems with Weyl-like quasi-particles but anisotropic dispersion relation $Ï^2 \sim k_\parallel^2 + k_\p…

Scale without conformal symmetry in hydrodynamics
Evangelos Afxonidis, Jewel Kumar Ghosh, Daniele Musso +2
Scale without conformal symmetry corresponds to an inhomogeneous conservation equation for the virial current sourced by the trace of the energy-momentum tensor. Fluids that are ju…
