Application of the Sampling and Replication Operators to Describe
... According to the uncertainty principle, the shorter the pulse duration, the wider the bandwidth of its spectrum. The cycle period of the central frequency of the spectrum is the natural limit of the pulse duration. The pulse whose duration is near this natural limit, is called an ultra-short pulse ( ...

... of the Dirac quantum field theory, axed around the notion of negativeenergy electrons. In that approach, there are only particles of charge −e but of positive and negative energy: their total number (fermionnumber) is conserved. We will see that this approach is a convenient one to study localized pr ...
