Bose-Einstein Condensation of Excitons and Biexcitons: And by S. A. Moskalenko, D. W. Snoke

By S. A. Moskalenko, D. W. Snoke

Bose-Einstein condensation of excitons is a special impact during which the digital states of an outstanding can self-organize to obtain quantum part coherence. The phenomenon is heavily associated with Bose-Einstein condensation in different structures reminiscent of liquid helium and laser-cooled atomic gases. protecting theoretical points in addition to fresh experimental paintings, the publication presents a finished survey of the sphere. After introducing the suitable simple physics of excitons, the authors talk about exciton-phonon interactions in addition to the habit of biexcitons. in addition they hide exciton phase-transitions and provides specific awareness to nonlinear optical results together with the optical Stark impact and chaos in excitonic platforms. The thermodynamics of equilibrium, quasiequilibrium, and nonequilibrium platforms are tested intimately. all through, the authors interweave theoretical and experimental effects. The ebook might be of significant curiosity to graduate scholars and researchers in semiconductor and superconductor physics, quantum optics, and atomic physics.

Handbook of Molecular Force Spectroscopy

Smooth fabrics technology and biophysics has more and more all for learning and controlling intermolecular interactions at the single–molecule point. The peer–reviewed literature includes a growing number of reports that both degree the interplay forces at once or use mechanical forces to deform the molecules or set off structural transitions.

Mathematical Theory of Elasticity of Quasicrystals and Its Applications

This inter-disciplinary paintings overlaying the continuum mechanics of novel fabrics, condensed subject physics and partial differential equations discusses the mathematical idea of elasticity of quasicrystals (a new condensed subject) and its functions by means of constructing new partial differential equations of upper order and their recommendations less than advanced boundary worth and preliminary price stipulations.

Glasses and Amorphous Materials

Fabrics technology and know-how is a seminal paintings and crucial reference supplying entry to a veritable compendium of data overlaying an important sessions of fabrics present in undefined, together with: metals, ceramics, glasses, polymers, semiconductors and composites. also, fabrics technology and know-how offers with the purposes, processing, and basic rules linked to those fabrics.

To start, this means we must review the basic theory of BEC of any kind of particle, the theory known as the Bogoliubov model, after the foundational contributions made by N.
