Role of partial stable stratification on the onset of rotating magnetoconvection with a uniform horizontal field
Tirtharaj Barman, Arpan Das, Swarandeep Sahoo
To explore the combined effects of partial thermal stable stratification and magnetic back-reaction within Earth's tangent cylinder, we study the onset of magnetoconvection in an i…
On Modular maximal-cyclic braces
Arpan Das, Arpan Kanrar
Inspired by a conjecture by Guarnieri and Vendramin concerning the number of braces with a generalized quaternion adjoint group, many researchers have studied braces whose adjoint…
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 expansio…
