Problems in the Lifshitz theory of dispersion forces

Abstract:
The Lishitz theory describes the van der Waals and Casimir forces which arise between two closely spaced material bodies due to the zero-point and thermal fluctuations of the electromagnetic field. A lot of precise measurements of the Casimir force performed during the last two decades revealed a puzzle. The theoretical predictions have been found in agreement with the measurement data only under a condition that in computations one disregards the relaxation properties of conduction electrons for metals and the dc conductivity for dielectrics. On the theoretical side it was found that if both these effects are included, one arrives to contradictions with thermodynamics. Possible resolution of this puzzle is discussed.
