A Reflection on the Scope of Feminist Pedagogy in Indian Tertiary Education
The Indian National Education Policy seek to restructure and standardize the higher education institution (HEI) curriculum and look forward to a futuristic, meritocratic, equitable, and multidisciplinary pedagogy. Present work critically analyses the scope of Feminist Pedagogy in the Indian higher education scenario, in this regard. It would try to offer an active participatory teaching-learning strategy to dismantle the existing gender hierarchy and oppression in Indian HEIs
Heavy quark damping rate in hot viscous QCD plasma
We derive an expression for the heavy quark damping rate in hot quark gluon
plasma in presence of flow. Here all the bath particles here are out of
equilibrium due to the existence of non-zero velocity gradient. The magnetic
sector shows similar infrared divergences even after hard thermal loop
corrections as one encounters in case of non-viscous plasma. We estimate the
first order correction in () for heavy quark damping rate due to the
non-zero viscosity of the QCD plasma.Comment: 19 pages, 1 figure, accepted for publication in PR
Dynamically screened strongly quantized electron transport in binary neutron-star merger
We examine electron-transport coefficients in magnetized hot and dense
electron-ion plasma relevant in binary neutron star merger simulation. We
calculate electrical and thermal conductivities in low density, high
temperature, highly magnetized plasma of binary neutron star mergers where
quantum oscillatory behavior of electrons emerge. For pronounced thermodynamic
effects, we consider zeroth Landau level population of electrons for the
calculation of conductivity. We solve Boltzmann equation in presence of
magnetic field to obtain the dissipative components of electrical and thermal
conductivities. The dissipative coefficients are formulated considering
frequency dependent dynamical screening in the quantized electron-ion
scattering rate. Numerical estimations show that the effect of dynamical
screening of photon propagator on electrical and thermal conductivities is
pronounced. We observe that dynamical screening reduces the maxima of both the
electrical and thermal conductivities by factors of thirty one and twenty
respectively leading to a reduction in the corresponding time scales of these
coefficients. The common scaling factor between electrical and thermal
conductivity is also observed to follow cubic relationship with temperature
violating Wiedemann-Franz law.Comment: Accepted in The European Physical Journal C. arXiv admin note:

Energy and momentum relaxation of heavy fermion in dense and warm plasma
We determine the drag and the momentum diffusion coefficients of heavy
fermion in dense plasma. It is seen that in degenerate matter drag coefficient
at the leading order mediated by transverse photon is proportional to
while for the longitudinal exchange this goes as . We
also calculate the longitudinal diffusion coefficient to obtain the Einstein
relation in a relativistic degenerate plasma. Finally, finite temperature
corrections are included both for the drag and the diffusion coefficients.Comment: 8 pages, 1 eps figure, typos corrected and paragraphs rearranged.
