Time-dependent electron phenomena at surfaces

Time-dependent electron phenomena at surfaces.

Femtosecond and subfemtosecond time scales typically rule electron dynamics at metal surfaces. Recent advance in experimental techniques permits now remarkable precision in the description of these processes. In particular, shorter time scales, smaller system sizes, and spin-dependent effects are current targets of interest. In this article, we use state-of-the-art theoretical methods to analyz...

Understanding protein adsorption phenomena at solid surfaces.

Protein adsorption at solid surfaces plays a key role in many natural processes and has therefore promoted a widespread interest in many research areas. Despite considerable progress in this field there are still widely differing and even contradictive opinions on how to explain the frequently observed phenomena such as structural rearrangements, cooperative adsorption, overshooting adsorption ...

Critical Phenomena at Interfaces Phase Transitions at Quantum Surfaces

Tlre qnantum systems helium and hydrogen provide a versatile testing ground for studying interfacial phenomena. As examples, both some properties of surface< near thermodynamic equilibrium, like layering and wetting, and uonequilibrium states of qucnch-condensed disordered films are discussed. A further topic is the development of macroscopic instabilities of interfaces under external perturbat...
