We investigate the existence and location of the surface phase known as the “Surface-Attached Globule” (SAG) conjectured previously to exist in lattice models of three-dimensional polymers when they are attached to a wall that has a short range potential. The bulk phase, where the attractive intra-polymer interactions are strong enough to cause a collapse of the polymer into a liquid-like globu...

The division of Germany after the second world war has often been recognised as providing a unique opportunity to evaluate “a natural experiment in history”, one in which a homogenous population had been artificially separated for 45 years. The possible consequences for health of exposure to two very diVerent social models have, however, received relatively little attention. When the Berlin Wal...

We refute the arguments by Anton in cond-mat/0004390, which set out to disprove the existence of a collapse transition for a randomly forced inelastic particle. An eprint by Anton [1] has recently appeared on this archive, criticizing our proposal of a collapse transition for an inelastic, randomly-forced particle [2]. Our conclusions were that a particle forced by Gaussian white noise that reb...
