Reduced Persistence Length and Fluctuation-Induced Interactions of Directed Semiflexible Polymers on Fluctuating surfaces
ArXiv cond-mat/9603069 (1996)
Abstract:
We consider directed semiflexible polymers embedded in a fluctuating surface which is governed by either surface tension or bending rigidity. The attractive interactions induced by the fluctuations of the surface reduce the rigidity of the polymers. In particular, it is shown that for arbitrarily stiff parallel polymers, there is a characteristic separation below which they prefer to bend rather than stay linear. The out-of plane fluctuations of the polymer, screen out the long-range fluctuation-induced forces, resulting in only a short-ranged effective attraction.A test theory of the local structure of spacetime: a Finslerian approach
Classical and Quantum Gravity 12:1 (1995) 273-278
Abstract:
For rival theories within the framework of the test theory of Mansouri - Sexl a geometrical setting in terms of Finsler geometry has been found. It is shown that the time dilation and length contraction parameters measure the deviation from a Riemannian geometry.Fluctuation-Induced Interactions between Rods on Membranes and Interfaces
ArXiv cond-mat/9509071 (1995)
Abstract:
We consider the interaction between two rods embedded in a fluctuating surface which is governed by either surface tension or rigidity. The modification of fluctuations by the rods leads to an attractive long-range interaction that falls off as $1/R^4$ with their separation. The orientational dependence of the resulting interaction is non-trivial and may lead to interesting patterns of rod-like objects on such surfaces.Controlling collective rotational patterns of magnetic rotors
