Friction of a driven chain: Role of momentum conservation, Goldstone and radiation modes
Debankur Das, Richard Vink, Matthias Krüger
We analytically study friction and dissipation of a driven bead in a 1D harmonic chain, and analyze the role of internal damping mechanism as well as chain length. Specifically, we…
Nematics with quenched disorder : violation of self-averaging
J. M. Fish, R. L. C. Vink
We consider the isotropic-to-nematic transition in liquid crystals confined to aerogel hosts, and assume that the aerogel acts as a random field. We generally find that self-averag…
Finite size scaling in Ising-like systems with quenched random fields: Evidence of hyperscaling violation
R. L. C. Vink, T. Fischer, K. Binder
In systems belonging to the universality class of the random field Ising model, the standard hyperscaling relation between critical exponents does not hold, but is replaced by a mo…
The isotropic-to-nematic transition in confined liquid crystals : an essentially non-universal phenomenon
J. M. Fish, R. L. C. Vink
Computer simulations are presented of the isotropic-to-nematic transition in a liquid crystal confined between two parallel plates a distance H apart. The plates are neutral and do…
Restricted orientation "liquid crystal" in two dimensions: Isotropic-nematic transition or liquid-gas (?)
T. Fischer, R. L. C. Vink
We present Monte Carlo simulation results of the two-dimensional Zwanzig fluid, which consists of hard line segments which may orient either horizontally or vertically. At a certai…
Liquid crystals in two dimensions: First-order phase transitions and nonuniversal critical behavior
R. L. C. Vink
Liquid crystals in two dimensions undergo a first-order isotropic-to-quasi-nematic transition, provided the particle interactions are sufficiently ``sharp and narrow''. This implie…
