Finite temperature effects on anisotropic pressure and equation of state of dense neutron matter in an ultrastrong magnetic field    [PDF]

A. A. Isayev, J. Yang

Spin polarized states in dense neutron matter with recently developed Skyrme effective interaction (BSk20 parametrization) are considered in the magnetic fields $H$ up to $10^{20}$ G at finite temperature. In a strong magnetic field, the total pressure in neutron matter is anisotropic, and the difference between the pressures parallel and perpendicular to the field direction becomes significant at $H>H_{th}\sim10^{18}$ G. The longitudinal pressure decreases with the magnetic field and vanishes in the critical field $10^{18}View original: http://arxiv.org/abs/1301.0544
