Plasmonic nature of van der Waals forces between nanoparticles
We propose a new approach to calculate van der Waals forces between
nanoparticles where the van der Waals energy can be reduced to the energy of
elementary surface plasmon oscillations in nanoparticles. The general theory is
applied to describe the interaction between 2 metallic nanoparticles and
between a nanoparticle and a perfectly conducting plane. Our results could be
used to prove experimentally the existence of plasmonic molecules and to
elaborate new control mechanisms for the adherence of nanoparticles between
each other or onto surfaces.Comment: 4 pages 5 figure
Conditional Acceptability for Random Variables
Acceptable random variables introduced by Giuliano Antonini et al. (J. Math. Anal. Appl. 338:1188-1203, 2008) form a class of dependent random variables that contains negatively dependent random variables as a particular case. The concept of
acceptability has been studied by authors under various versions of the definition, such as extended acceptability or wide acceptability. In this paper, we combine the concept of acceptability with the concept of conditioning, which has been the
subject of current research activity. For conditionally acceptable random variables, we provide a number of probability inequalities that can be used to obtain asymptotic results
