Geometric optics analysis in Lorentz violating Chern-Simons electrodynamics
Arpan Das, Hriditi Howlader, Alekha C. Nayak
We study the geometric optics limit of the electrodynamics in the presence of Lorentz violating Chern-Simons term in (3+1) dimensions. The Chern-Simons term couples the dual electr…

Kubo formula for spin hydrodynamics: spin chemical potential as leading order in gradient expansion
Sourav Dey, Arpan Das
We present a first-order dissipative spin hydrodynamic framework, where the spin chemical potential is treated as the leading term in the hydrodynamic gradient expansion,…
