density of quantum states in periodical structures
... New quantum effects have been studied in thin nanograting layers. Nanograting on the surface imposes additional boundary conditions on the electron wave function and reduces the density of states. When the dimensions of the nanograting are close to the De Broglie wavelength the density of states red ...

... Now consider the case of a ‘chirped’ frequency such that φ̇(t) = −αt for −T < t < T . Hrot (t) now varies with time, but if its matrix elements vary slowly (i.e. if α is small), and there is no level crossing, the adiabatic theorem should apply. This means that the system remains in the ‘same’ eigen ...
