The critical Casimir force (CCF) arises from confining fluctuations in a fluid and thus it is fluctuating quantity itself. While the mean CCF universal, its (static) variance has previously been found to depend on microscopic details of system which effectively set large-momentum cutoff underlying field theory, rendering potentially large. This raises question how properties are reflected exper...

In this Letter, we consider a liquid mixture confined between two thermally conducting walls subjected to a stationary temperature gradient. While in a one-component liquid nonequilibrium fluctuation forces appear inside the liquid layer, nonequilibrium fluctuations in a mixture induce a Casimir-like force on the walls. The physical reason is that the temperature gradient induces large concentr...

The Casimir force, which is the attraction of two uncharged material bodies due to modification of the zero-point energy associated with the electromagnetic modes in the space between them, has been measured with per cent-level accuracy in a number of recent experiments. A review of the theory of the Casimir force and its corrections for real materials and finite temperature are presented in th...
