... iΠµν (k), where k is the (off-shell) photon momentum flowing through the diagram. Show that the loop integral is convergent (or more precisely, the divergent parts cancel), and express it in the form, i Πµν (k) = g µν F (k 2 ) + k µ k ν G(k 2 ). You may leave F (k 2 ) and G(k 2 ) as integrals over a ...

Quantum Coherence between States with Even and Odd Numbers of Electrons
... In 1952, Wick, Wightman, and Wigner [1] claimed that the coherent linear superpositions of states with even and odd numbers of fermions are incompatible with the Lorentz invariance and introduced the superselection rule, according to which such linear superpositions are physically impossible. In act ...

Quantum mechanics
... The propagator thus represents the time-evolution of a wave packet starting out as a configuration space delta-function localized at the point q′ at initial time t = 0. For time-independent Hamiltonians, the time dependence of the wave functions is known as soon as the eigenenergies En and eigenfunc ...

QFT on curved spacetimes: axiomatic framework and applications

It states that each degree of freedom is influenced only by a relatively small number of other degrees of freedom. This induces a concept of neighborhood ...

Parallel Universes
... Our observation on these weird areas in space that conflict laws of physics, changes how they react. For instance, the forces on the object change. This theory also leads to the idea that life is all in our heads. After all, if a tree falls and no one is there to hear it, does it make a sound? Photo ...

Standard quantum mechanics gives no clear guidance about how the line between the two parts of the world ...
