Research Interest Quantum Chromodynamics (QCD) is the theory of the strong color forces among the quarks. QCD at finite temperature and chemical potential plays an important role to understand the different transitions that took place in the early universe, after a few micro seconds from the Big Bang. As it is known, the observable degrees of freedom of quantum chromodynamics (QCD) at low temperature are the color-singlet hadrons, while at high temperature, these composite objects split up in a new phase where the dominant degrees of freedom are quarks and gluons. This phase transition is referred to as confinement-deconfinement transition. The vanishing of dynamically generated quark mass at high temperature and/or chemical potential corresponds to another type of transition i.e., chiral symmetry restoration, while at zero temperature and chemical potential, chiral symmetry is broken. Thus, when the strength of the QCD interaction diminishes with increasing temperature and chemical, only the current quark masses survive when temperature and chemical exceed a set of critical values. This is the chiral symmetry breaking-restoration phase transition. As for experiment is concerned, implications of chiral symmetry breaking for the elastic and transition form factors of mesons and baryons form an integral part of the planned program at the $12$ GeV upgrade of the Thomas Jefferson National Accelerator Facility in Virginia. There are other experiments around the world that might help to understand the confinement and chiral transitions like RHIC in Brookhaven, LHC at CERN, and future experiment proposals like CBM at FAIR, in Germany. In the past few years, the effect of an external magnetic field on the QCD phase transitions has opened an interesting area of research where phenomena such as Magnetic Catalysis (MC) and Inverse Magnetic Catalysis (IMC) could take place and modify the behavior of hadron matter. Experimental motivation behind this fact comes from peripheral heavy-ion collisions, since not all the nucleons are participants in the reaction, because they are electric charges in motion, they produce in the interaction region a very strong magnetic field which quickly weakens, but whose effects can be measured in experiments.

5 There are several approaches (Schwinger-Dyson Equations, Lattice and effective models (NJLmodel, Linear sigma model etc.) to understand the QCD Phase transitions. I am basically interested in to understand these phase transitions by using Schwinger-Dyson equations and also from some effective model like NJL etc. I am also interested in to understand how the magnetic field effect the QCD phase diagram under the influence of strong magnetic field at zero density as well as at finite density, at zero temperature but finite density.
