Computationally Efficient Field-Theoretic Simulations for Block Copolymer Melts
Beardsley, T.M.; Spencer, R.K.W.; Matsen, M.W. (American Chemical Society, 2019-11-12)Field-theoretic simulations (FTS) provide fluctuation corrections to self-consistent field theory (SCFT) by simulating its field-theoretic Hamiltonian rather than applying the saddle-point approximation. Although FTS work ... -
Fluctuation correction for the critical transition of symmetric homopolymer blends
Beardsley, Tom; Matsen, Mark (AIP, 2017-07)Monte Carlo simulations are performed on structurally symmetric binary homopolymer blends over a wide range of invariant polymerization indexes, N. A finite-size scaling analysis reveals that certain critical exponents ... -
Testing the Universality of Entropic Segregation at Polymer Surfaces
Mahmoudi, Pendar; Forrest, William; Beardsley, Tom; Matsen, Mark (2018)This study addresses entropic segregation effects at the surfaces of monodisperse and bidisperse melts. For the monodisperse melts, we focus on the segregation of chain ends to the surface, and for the bidisperse melts, ...
