Exact relations between running of αs and α in N = 1 SQCD + SQED
Resumo
In N = 1 supersymmetric QCD and QED theory we derive the (all-order) exact equations relating the renormalization group behaviour of the strong and electromagnetic couplings and prove that they are valid in the combined higher covariant derivative regularized and minimal subtraction of logarithms renormalized prescription. In particular, the β-function of N = 1 supersymmetric QCD can be expressed in terms of the Adler D-function. If all flavors have the same absolute value of the electromagnetic charges, it is also possible to write a simple relation between the β-functions for the strong and electromagnetic coupling constants. In this particular case there is a special renormalization group invariant relation.

Non Fermi-liquid magnetoresistance oscillations in quasi-one-dimensional conductors
Resumo
We theoretically demonstrate that strong non Fermi-liquid magnetic oscillations of electron–electron scattering time can exist in quasi-one-dimensional conductors under condition of the magnetic breakdown between two open electron orbits. They are shown to be due to electron–electron interactions in a metallic phase under condition of the magnetic breakdown and they are beyond the Fermi-liquid theory. In particular, we consider as example the organic conductor (TMTSF)2ClO4 and perform both analytical and numerical calculations for its known electron spectrum. We also argue that similar oscillations of resistivity can exist in a metallic phase of another quasi-one-dimensional organic conductor – (Per)2Au(mnt)2.
