This book presents original research results on the leading edge of physics. Each article has been carefully selected in an attempt to present substantial research across a broad spectrum. Topics include the theoretical study of the superconducting phase in metallic complexes; monolithic phosphor-free white emission by InGaN/GaN quantum wells; intra-band electron raman scattering in semiconductor quantum wells and laser applications; a role of zero point energy in the universe expansion; gravitational communication; non-linear optical effects in intersubband transitions of semiconductor quantum wells; dark matter cluster generated by Moon's motion; and entangled single purely quantum universe in the multiverse.
