2d affine XY-spin model/ 4d gauge theory duality and deconfinement
Mohamed M. Anber, Erich Poppitz, Mithat Unsal
We introduce a duality between two-dimensional XY-spin models with symmetry-breaking perturbations and certain four-dimensional SU(2)and SU(2)/Z_2 gauge theories, compactified on a…
On the running of the gravitational constant
Mohamed M. Anber, John F. Donoghue
We show that there is no useful and universal definition of a running gravitational constant, G(E), in the perturbative regime below the Planck scale. By consideration of the loop…
Microscopic Structure of Magnetic Bions
Mohamed M. Anber, Erich Poppitz
Magnetic bions---stable bound states of monopoles and twisted ("Kaluza-Klein") monopoles, carrying two units of magnetic charge---have been shown to be the leading cause of confine…
The emergence of a universal limiting speed
Mohamed M. Anber, John F. Donoghue
We display several examples of how fields with different limiting velocities (the "speed of light") at a high energy scale can nevertheless have a common limiting velocity at low e…
