Generation of nonclassical states from thermal radiation
... is highly singular or not positive, i.e. it cannot be interpreted as a classical probability distribution. In general however, since the P function can be badly behaved, it cannot be connected to any observable quantity. A conceptually simple way to generate a quantum light state with a varying degr ...

Non perturbative QCD
... 3) Last but not least: we must learn how to compute physical quantities. This is the hard part for QCD. Example, the 4 theory: the field is a real function of space-time. Te Lagrangian defines its dynamics (we shall see how): L = 1/2 (∂µ(x))2 - 1/2 m2 2 (x) - /4! 4(x) The action is defined for ...

Whether a particular component is the desired one or not is decided by base-pairing, and it is a simple yes/no query – either the base-pairing takes place or it does not. The optimizat ...
