Theoretical Physics Research Developments (Hardcover)

This book presents and discusses current research developments in the study of theoretical physics. Topics discussed include dark energy as the source of the time-dependent Einstein cosmological constant; non-linear refractive index theory; quantum coherence and tuneable transient behaviour of a double-control four-level atomic vapour; laser prototyping of polymer-based nanoplasmonic components and radiative transitions of mesons in an independent-quark potential model.
