 abstract = {The bending rigidity kappa of bilayer membranes was studied with coarse
grained soft repulsive potentials using dissipative particle dynamics
(DPD) simulations. Using a modified Andersen barostat to maintain the
bilayers in a tensionless state, the bending rigidity was obtained from
a Fourier analysis of the height fluctuations. From simulations carried
out over a wide range of membrane thickness, the continuum scaling
relation kappa proportional to d(2) was captured for both the L-alpha
and L-beta phases. For membranes with 4 to 6 tail beads, the bending
rigidity in the L-beta phase was found to be 10-15 times higher than
that observed for the L-alpha phase. From the quadratic scalings
obtained, a six fold increase in the area stretch modulus, k(A) was
observed across the transition. The magnitude of increase in both kappa
and k(A) from the L-alpha to the L-beta phase is consistent with current
experimental observations in lipid bilayers and to our knowledge
provides for the first time a direct evaluation of the mechanical
properties in the L-beta phase.},
