Attractive interaction between steps

Attractive Interaction between Steps 16 DECEMBER 1991

The interaction potential between steps on low index surfaces is of central importance for the equilibrium shape of crystals, step roughening on vicinal surfaces, and the dynamics of crystal growth. The equilibrium shape of crystals, e.g. , is determined by the dependence of the surface free energy on the orientation of the surface [I]. Step-step interactions enter thirdand higher-order terms i...

Rhythmic Synchrony for Attractive Human-Robot Interaction

We are investigating the role and cognitive mechanisms of rhythm and synchrony in human-robot social interaction. One of our targets is nonverbal interactive dance-oriented play between children and a creature-like robot, Keepon. We present here the background of our research, the robot we are currently using for this research, techniques for the perception and generation of rhythmic actions, a...

Bosonic clouds with attractive interaction beyond the local interaction approximation

We study the properties of a Bose–Einstein condensed cloud of atoms with negative scattering length confined in a harmonic trap. When a realistic non local (finite range) effective interaction is taken into account, we find that, besides the known low density metastable solution, a new branch of Bose condensate appears at higher density. This state is self–bound but its density can be quite low...
