In recent times the interplay among dynamical platforms thought and non-equilibrium statistical mechanics has been huge, immense. the invention of fluctuation theorems as a primary constitution universal to just about all non-equilibrium platforms, and the connections with the unfastened strength calculation tools of Jarzynski and Crooks, have excited either theorists and experimentalists.

[R(a-R(Oe]}\. 3) Further simplification is achieved if pairwise interactions are assumed to s be the dominant interaction. The difference R(f')p ~ R(î')q i expressed as , R ( i ' ) ! — r(f'), where R ( i ) i locates the center of mass of one of the particles and r(f') represents the location of particle 2 from a coordinate system whose o v er a origin is at particle 1.

If the particles are noninteracting (AH = 0), then AG[AC p (r,0)] = — T A S [ A C p ( r , 0 ) ] . 2) AVNA, where <«,>„ is the uniform (equilibrium) number of particles in the volume and <5n, is the number fluctuation. n !. 3) 3 < n i > u! < n 2 > u ! < « 3 > u ! 4) u with < C P > U = C p .

The agreement is quite good. 8. 1) and 2 ^ L ' · 2 ) ( 1 8 where yL and Y|( are "end effects" and ρ = L/2RC. Broersma (1960a, 1960b) first examined the "end effects" on the translational diffussion of cylinders. Tirado and Garcia de la Torre (1979) examined the end effects for both a "capped" cylinder and an "open-ended" cylinder, where they used spherical subunits to mimic the cylinder surface (the "shell model"). Their calculations involved a series of bead radii and an extrapolation to σ = 0, which would be the classical limit to a smooth surface.
