Cosmological Symmetry Breaking and Generation of Electromagnetic Field [PDF]

open access: yes, 2010
Cosmological phase transitions accompanied by some kind of symmetry breaking would cause the creation of topological defects and the resulting production of primordial magnetic field.

Nucleation and growth of sodium colloids in NaCl under irradiation: theory and experiment [PDF]

open access: yes, 2005
A mechanism of radiation-induced emission of Schottky defects from extended defects proposed originally for metals has recently been applied to ionic crystals, where it is based on interactions of excitons with extended defects such as dislocations and ...
