... The total W-decay rate is independent of polarization; this has to be the case as the decay rate cannot depend on the arbitrary definition of the z-axis For a sample of unpolarized W boson each polarization state is equally likely, for the average matrix element sum over all possible matrix elem ...

Three problems from quantum optics
... The third topic, fermion coherent states, deals with generalization to fermion fields of coherent states, one of the key concepts of quantum optics. Each of these topics is described briefly below and in detail in a separated chapter. I have tried to write this thesis clearly so that a physicist not ...

Multiprobe quantum spin Hall bars
... In conclusion, we have studied multi-terminal QSH devices based on the Büttiker approach of ballistic edge transport. We have derived expressions for resistances in three-, four- and six-terminal geometries and compared these to the ones obtained for the corresponding QH bars. Furthermore, we have ...
