In order to add an electron to the dot, sufficient energy must be supplied to overcome this charging energy, either through changing a gate voltage or applying a source to drain voltage VSD . Electrons can therefore be ...

It is therefore important to keep the computational work necessary to calculate the particle forces as low as possible since the forces have to be calculated for each particle. ...

Useful Concepts from Information Theory
... never infinite, we sometimes have to send atypical messages. Real coding schemes handle this by having a code word for every possible message (not merely the typical messages), but they use short code words for typical messages, and long code words for atypical messages. This allows one to get close ...

Neutrino Mass and Direct Measurements
... since we have shown previously that ψL ψL = ψR ψR = 0. The important point to note is that a non-zero Dirac mass requires a particle to have both a leftand right-handed chiral state : in fact the Dirac mass can be viewed as being the coupling constant between the two chiral components. As it stands ...
