An optical lattice is formed by the interference of counter-propagating laser beams, creating a spatially periodic polarization pattern. The resulting periodic potential may trap neutral atoms via the Stark shift. Atoms are cooled and congregate in the locations of potential minima. The resulting arrangement of trapped atoms resembles a crystal lattice. This book presents current research from across the globe in the study of optical lattices, including optical lattices prepared by laser treatment on polymers, peculiarities of magnetooptical properties in crystals with mixed valence centers;...

Between wars (1918-1939) Benjamin Jarnes (1888-1949) was considered among the most appreciated Spanish writers, and his novels were distinguished by the European critiques of the time. "Locura y muerte de Nadie," along "Paula y Paulita," "Escenas junto a la muerte" and "Teoria del zumbel," belong to a fiction cycle, unique in the peninsular narrative of those years; novels in which Jarnes experiments with the new forms of metafiction to highlight the existential condition of the human being in the newly technified mass society. "Locura y muerte de Nadie," simultaneously "agonic" and...
