    "abstract": "Position holds a very special role in understanding the classical behaviour\nof macroscopic bodies on the basis of quantum principles. This lead us to\nexamine the localised states of a large condensed object in the context of a\nrealistic model. Following the argument that an isolated macroscopic body is\nusually described by a linear superposition of low-lying energy eigenstates, it\nhas been found that localised states of this type correspond to a nearly\nminimum-uncertainty state for the center of mass. An indication is also given\nof the dependence of the center of mass position spread on the number of\nconstituent particles.\n  This paper is not offered as an answer to the intriguing question of the\npreferred role played by the position basis, but will hopefully provide some\ncontribution to the quantum modelling of multi-particle systems.",
