... not actually require one to know or even be able to have these states in hand. Let’s pretend that we know the quantum states that pertain to N molecules in a container of volume V as shown in Fig. 7.2, and let’s label these states by an index J. That is J=1 labels the lowest-energy state of N molecu ...

... from the master. The stamp was subsequently inked by applying a small amount of a solvent using a Q-tip. The spincoated polymer film was placed in contact with the inked stamp. As the stamp material is elastomeric, conformal contact was easily made with the polymer film. The solvent on the stamp dis ...

Review of Cold Rydberg Atoms and Their Applications

... The strong interaction between Rydberg atoms was observed first in Rydberg dipole blockage experiments [52, 53] and later more clearly in long-range Rydberg molecular resonance experiments. In the latter, molecular resonance features were found in the excitation spectra of ultra-cold atoms of rubidiu ...

... from a log-log plot as in the 3D case. Since the transitions became very broad, we characterized them by an error function fit, with the center of the fitted error function taken as the center of the transition (Fig. 4). In the 1D system, at a very shallow lattice depth of 0.25 ER (corresponding to ...

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.
