Dense nuclear matter in a strong magnetic field

We investigate in a relativistic Hartree theory the gross properties of cold symmetric nuclear matter and nuclear matter in beta equilibrium under the influence of strong magnetic fields. If the field strengths are above the critical values for electrons and protons, the respective phase spaces are strongly modified. This results in additional binding of the systems with distinctively softer equations of state compared to the field free cases. For magnetic field $\sim 10^{20}$ Gauss and beyond, the nuclear matter in beta equilibrium practically converts into a stable proton rich matter.

Expulsion of Magnetic Flux Lines from Growing Superconducting Core of a Quark Star and The Possibility of Mullins-Sekerka Interface Instability

The expulsion of magnetic flux lines from a growing superconducting core of a quark star has been investigated using the idea of impurity diffusion in molten alloys. The possibility of Mullins-Sekerka normal-superconducting interface instability has also been studied.

Quark Matter in Strong Magnetic Field

The effect of strong magnetic field on the stability and gross properties of bulk as well as quasi-bulk quark matter has been investigated using the conventional MIT bag model. Both the Landau diamagnetism and the paramagnetism of quark matter has been studied. How the quark hadron phase transition is affected by the presence of strong magnetic field has also been investigated. The equation of state of strange quark matter changes significantly in strong magnetic field. It is also shown that the thermal nucleation of quark bubbles in compact metastable state of neutron matter is completely forbidden in presence of strong magnetic field.
