摘要
We investigate the structure of the system consisting of rigid spherical particles confined in a freely supported soft membrane tube. We show that a number of characteristically different phases exist depending on the phenomenological parameters in the Helfrich model describing the tubular membrane as well as an adsorption energy describing the attraction between the sphere surface and the tube interior wall.
