M ay 2 00 6 Theory of friction : contribution from fluctuating electromagnetic field
نویسندگان
چکیده
We calculate the friction force between two semi-infinite solids in relative parallel motion (velocity V), and separated by a vacuum gap of width d. The friction force result from coupling via a fluctuating electromagnetic field, and can be considered as the dissipative part of the van der Waals interaction. We consider the dependence of the friction force on the temperature T , and present a detailed discussion of the limiting cases of small and large V and d.

9 M ay 2 00 6 Enhancement of the non - contact friction between closely spaced bodies by two - dimension systems
We consider the effect of an external bias voltage and the spatial variation of the surface potential, on the damping of cantilever vibrations. The electrostatic friction is due to energy losses in the sample created by the electromagnetic field from the oscillating charges induced on the surface of the tip by the bias voltage and spatial variation of the surface potential. A similar effect ari...

We study the van der Waals friction between two flat metal surfaces in relative motion. For good conductors we find that normal relative motion gives a much larger friction than for parallel relative motion. The friction may increase by many order of magnitude when the surfaces are covered by adsorbates, or can support low-frequency surface plasmons. In this case the friction is determined by r...

We study the non-contact friction between an atomic force microscope tip and a metal substrate in the presence of bias voltage. The friction is due to energy losses in the sample created by the electromagnetic field from the oscillating charges induced on the tip surface by the bias voltage. We show that the friction can be enhanced by many orders of magnitude if the adsorbate layer can support...
متن کاملComment on “ No quantum friction between uniformly moving plates ”
All bodies are surrounded by a fluctuating electromagnetic field due to thermal and quantum fluctuations of the current density inside the bodies. This fluctuating field is responsible for many important phenomena such as the radiative heat transfer, the van der Waals interaction and the van der Waals friction between bodies. In contrast to the van der Waals interaction, for which theory is wel...
متن کاملFrictional drag between quantum wells mediated by fluctuating electromagnetic field
We use the theory of the fluctuating electromagnetic field to calculate the frictional drag between nearby two-and three dimensional electron systems. The frictional drag results from coupling via a fluctuating electromagnetic field, and can be considered as the dissipative part of the van der Waals interaction. In comparison with other similar calculations for semiconductor two-dimensional sys...
