(Anti)kaon condensation in strongly magnetized dense matter

Recent observations of several massive pulsars, with masses near and above 2M⊙, point towards the existence of matter at very high densities, compared to normal matter that we are familiar with in our terrestrial world. This leads to the possibility of the appearance of exotic degrees of freedom other than nucleons inside the core of the neutrons stars (NSs). Another significant property of NSs is the presence of a high surface magnetic field, with the highest range of the order of ≈1016 G. We study the properties of highly dense matter with the possibility of the appearance of heavier strange and nonstrange baryons, and kaons in the presence of a strong magnetic field. We find that the presence of a strong magnetic field stiffens the matter at high density, delaying the kaon appearance and, hence, increasing the maximum attainable mass of NS family.
