Asymptotic freedom and higher derivative gauge theories
M. Asorey, F. Falceto, L. Rachwal
The ultraviolet completion of gauge theories by higher derivative terms can dramatically change their behavior at high energies. The requirement of asymptotic freedom imposes very…
On the regularization of Lifshitz-type field theories
Alfio Bonanno, Miok Park, Lesław Rachwał +1
We consider Lifshitz-type scalar theories with explicit breaking of the Lorentz symmetry that, in addition, exhibit anisotropic scaling laws near the ultraviolet fixed point. Using…
Dark side of Weyl gravity
Petr Jizba, Lesław Rachwał, Stefano G. Giaccari +1
With the help of a functional renormalization group, we study the dynamical breakdown of scale invariance in quantum Weyl gravity by starting from the UV fixed point that we assume…
Effective Action from the Functional Renormalization Group
Nobuyoshi Ohta, Leslaw Rachwal
We study the quantum gravitational system coupled to a charged scalar, Dirac fermions, and electromagnetic fields. We use the "exact" or "functional" renormalization group equation…
Spectral action approach to higher derivative gravity
Ravi Mistry, Aleksandr Pinzul, Lesław Rachwał
We study the spectral action approach to higher derivative gravity. The work focuses on the classical aspects. We derive the complete and simplified form of the purely gravitationa…
