Scaling functions for the O(4)-model in d=3 dimensions
Jens Braun, Bertram Klein
A non-perturbative Renormalization Group approach is used to calculate scaling functions for an O(4) model in d=3 dimensions in the presence of an external symmetry-breaking field.…
Renormalization-scale independence of the physical cosmological constant
Robert Foot, Archil Kobakhidze, Kristian L. McDonald +1
Treating the metric as a classical background field, we show that the cosmological constant does not run with the renormalization scale -- contrary to some claims in the literature…
CPT theorem in a (5+1) Galilean space-time
M. Kobayashi, M. de Montigny, F. C. Khanna
We extend the 5-dimensional Galilean space-time to a (5+1) Galilean space-time in order to define a parity transformation in a covariant manner. This allows us to discuss the discr…
An 8-dimensional realization of the Clifford algebra in the 5-dimensional Galilean space-time
M. Kobayashi, M. de Montigny, F. C. Khanna
We give an 8-dimensional realization of the Clifford algebra in the 5-dimensional Galilean space-time by using a dimensional reduction from the Minkowski space-time to the…
Cold Nuclear Matter In Holographic QCD
Moshe Rozali, Hsien-Hang Shieh, Mark Van Raamsdonk +1
We study the Sakai-Sugimoto model of holographic QCD at zero temperature and finite chemical potential. We find that as the baryon chemical potential is increased above a critical…
