Do Feynman diagrams have only a time but also a space-axis?

Before all of you cry out "No, stupid, they live in momentum space" I would like to remark that (i) why, then, is there never a momentum-axis attached to them and (ii) the renowned physicist Sivan...

How do super-resolution and the uncertainty principle relate?

Heisenberg famously introduced and illustrated the uncertainty principle with a hypothetical gamma-ray microscope experiment. The diffraction limit played a central role in this derivation....

Why are many particle states described by a Tensor product?

A single quantum state can be represented by a ray in a Hilbert space. That you need a vector space to describe it can be motivated quite intuitively. E.g. you may analyze a sequence of spin...

Can the image formation in stochastic localization microscopy (like STORM or PALM) be described as a convolution?

The image formation for an optical system can be usually described by the convolution of the object intensity and the point-spread function (PSF) of the system. Localization microscopy (e.g. STORM...

Inequivalent Representations in QFT

Quantum Field Theory has the known problem of (unitary) in-equivalent representations. Is there any e.g. prediction actually affected by this ambiguity?

Would we call gluons, photons and the like "exchange particles" if Feynman diagrams had not been invented?

According to common understanding the fundamental interactions of the standard model are mediated by the exchange of so-called gauge bosons (photon, gluon etc.). Now, the e.g. number of gauge...
