Vacuum pressures and energy in a strong magnetic field
H. Perez Rojas, E. Rodriguez Querts
We study vacuum in a strong magnetic field. It shows a nonlinear response, as a ferromagnetic medium. Anisotropic pressures arise, and a negative pressure is exerted in the directi…
Effect of a Magnetic Field on the Electroweak Symmetry
E. Rodriguez Querts, H. Perez Rojas, A. Perez Martinez
We discuss the effect of a strong magnetic field in the behavior of the symmetry of an electrically neutral electroweak plasma. We analyze the case of a strong field and low temper…
Negative Pressures and Energies in Magnetized and Casimir Vacua
H. Perez Rojas, E. Rodriguez Querts
We study the electron-positron vacuum in a strong magnetic field in parallel with Casimir effect. Use is made of the energy-momentum tensor, taken as the zero temperature and z…
Magnetic Collapse of a Neutron Gas: No Magnetar Formation
Aurora Perez Martinez, Hugo Perez Rojas, Herman J. Mosquera Cuesta
A degenerate neutron gas in equilibrium with a background of electrons and protons in a magnetic field exerts its pressure anisotropically, having a smaller value perpendicular tha…
