Coupling between Internal Spin Dynamics and External

... As nonwhite noise spectra are common in background and technical noise (e.g., in the radio-frequency regime), and may be very significant in some types of apparatuses such as atom chips [15], these findings may serve to better understand how noise couples to quantum systems based on trapped atoms. F ...

Tight binding

In solid-state physics, the tight-binding model (or TB model) is an approach to the calculation of electronic band structure using an approximate set of wave functions based upon superposition of wave functions for isolated atoms located at each atomic site. The method is closely related to the LCAO method used in chemistry. Tight-binding models are applied to a wide variety of solids. The model gives good qualitative results in many cases and can be combined with other models that give better results where the tight-binding model fails. Though the tight-binding model is a one-electron model, the model also provides a basis for more advanced calculations like the calculation of surface states and application to various kinds of many-body problem and quasiparticle calculations.
