Anisotropic line tension of lipid domains in monolayers
E. Velasco, L. Mederos
We formulate a simple effective model to describe molecular interactions in a lipid monolayer. The model represents lipid molecules in terms of two-dimensional anisotropic particle…
Molecular ordering in lipid monolayers: an atomistic simulation
S. Panzuela, D. P. Tieleman, L. Mederos +1
We report on atomistic simulations of DPPC lipid monolayers using the CHARMM36 lipid force field and four-point OPC water model. The entire two-phase region where domains of the `l…
Hard-body models of bulk liquid crystals
Luis Mederos, Enrique Velasco, Yuri Martinez-Raton
Hard models for particle interactions have played a crucial role in the understanding of the structure of condensed matter. In particular, they help to explain the formation of ori…
Two-dimensional nematics in bulk and confined geometries
Daniel de las Heras, Yuri Martinez-Raton, Luis Mederos +1
Two-dimensional nematics possess peculiar properties that have been studied recently using computer simulation and various theoretical models. Here we review our own contribution t…
Density-functional study of defects in two-dimensional circular nematic nanocavities
D. de las Heras, L. Mederos, E. Velasco
We use density--functional theory to study the structure of two-dimensional defects inside a circular nematic nanocavity. The density, nematic order parameter, and director fields,…
Capillary and anchoring effects in thin hybrid nematic films and connection with bulk behavior
D. de las Heras, L. Mederos, E. Velasco
By means of a molecular model, we examine hybrid nematic films with antagonistic anchoring angles where one of the surfaces is in the strong anchoring regime. If anchoring at the o…
