We consider two bidimensional random models characterised by the following features: (a) their Hamiltonians are separable in polar coordinates and (b) the random part of the potential depends either on the angular coordinate or on the radial one, but

Haemorrhoids, a common ailment afflicting mostly Western patients, can produce bothersome symptoms, in particular pain, pruritus, and bleeding. There is a wide choice of surgical treatment options available for haemorrhoids in patients that cannot be

It was recently shown that wavepackets with skewed momentum distribution exhibit a boomerang-like dynamics in the Anderson model due to Anderson localization: after an initial ballistic motion, they make a U-turn and eventually come back to their sta

Electronic states and transport properties in the Kronig–Penney model with correlated compositional and structural disorder

Autor: L. Tessieri, Felix M. Izrailev, J. C. Hernández-Herrejón

Publikováno v: Physica E: Low-dimensional Systems and Nanostructures. 42:2203-2210

We study the structure of the electronic states and the transport properties of a Kronig-Penney model with weak compositional and structural disorder. Using a perturbative approach we obtain an analytical expression for the localisation length which
