Engineering Physics Annotation << Back ON THE PLASMA PROPERTIES OF A GAS CONSISTING OF LIGHT DIPOLE PARTICLES Nedospasov A.V. A gas of light Bose particles with electric dipole moments is considered. When dipole moments in the gas are oriented by an external electric field, this together with the dipole-dipole interaction produces pressure anisotropy. The pressure is negative along the field direction, and positive in a perpendicular direction. The media instable due to a negative internal pressure can be stabilized by Bose-Einstein condensation. This stabilization gives a relation between the mass of a particle, its dipole moment, and a scattering length which in Bose-Einstein condensate corresponds to a minimal distance between particles. In a Bose gas with oriented dipole moments, there can be pressure waves similar to the electron plasma waves. They can affect the propagation of electromagnetic waves. Dense enough, heterogeneous clusters of light dipole particles, if formed in Space, may affect the propagation of light from distant objects. Key words: axions, dipole moment, plasma, Bose gaseous, Bose-Einstein condensate, dipole interaction. Contacts: E-mail: a-nedospasov@yandex.ru Pp. 11-13.
