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…
Self-Magnetization of charged particles and Bose-Einstein Condensation
H. Perez Rojas, A. Perez Martinez, H. Mosquera Cuesta
We discuss the Bose-Einstein condensation of relativistic vector charged particles in a strong external magnetic field in very dense matter, as may be paired spin-up electrons. We…
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…
