Classical and quantum nonlocal gravity
Arnau Bas i Beneito, Gianluca Calcagni, Lesław Rachwał
This chapter of the Handbook of Quantum Gravity aims to illustrate how nonlocality can be implemented in field theories, as well as the manner it solves fundamental difficulties of…
Ultraviolet-complete quantum field theories with fractional operators
Gianluca Calcagni, Lesław Rachwał
We explore quantum field theories with fractional d'Alembertian . Both a scalar field theory with a derivative-dependent potential and gauge theory are super-renormalizable…
Introduction to Quantization of Conformal Gravity
Lesław Rachwał
A method for consistent quantization of conformal gravity treating conformal symmetry in a very controllable way is presented. First, we discuss local conformal symmetry in the fra…
Ultraviolet Finiteness or Asymptotic Safety in Higher Derivative Gravitational Theories
Leslaw Rachwal
We present and discuss well known conditions for ultraviolet finiteness and asymptotic safety. The requirements for complete absence of ultraviolet divergences in quantum field the…
