My research centers on the study of quantum chromodynamics (QCD) matter under extreme conditions — including high temperatures, strong magnetic fields, and high baryon densities. These environments are particularly relevant to the physics of neutron stars, heavy-ion collisions, and the early universe. By investigating how quarks and gluons behave in such regimes, my work aims to deepen our understanding of the QCD phase structure, the properties of strongly interacting matter, and the fundamental mechanisms governing the strong nuclear force in extreme astrophysical and cosmological settings.

This study explores neutrino emission from strongly magnetized dense quark matter in compact stars using field-theoretic methods. It accounts for Landau-level quantization of electrons while neglecting it for quarks, analyzing emission rate modifications and asymmetries due to magnetic fields. The findings have implications for stellar cooling and potential pulsar kicks.

Anisotropic charge transport in strongly magnetized relativistic matter
Reference:
Using quantum field theory and Kubo's formalism, we study electrical charge transport in hot magnetized plasma, deriving conductivity tensors from fermion damping rates in Landau levels. Our results show strong anisotropy: the transverse conductivity is suppressed due to charge trapping, while the longitudinal conductivity is enhanced, with extensions to strongly coupled quark-gluon plasma.

Utilizing leading-order results for the damping rates within a gauge theory, we derive the transverse and longitudinal conductivities for a strongly magnetized plasma.
⭐Earlier studies (Phys.Rev.D 103, 074019 (2021); Phys.Rev.D 99, 094002 (2019)) tackled chiral susceptibility and anisotropic pressure in the thermomagnetic regime, shedding light on QCD phase transitions.
