Contribution

It introduces and discusses the potential for novel infrared phenomena and UV/IR mixing in quantum gravity, extending effective field theory approaches.

Findings

UV/IR mixing can lead to observable effects in quantum gravity.

Infrared modifications may impact cosmological models.

Relaxed locality notions influence quantum information science.

Abstract

We discuss the possible appearance of several rather exotic phenomena in quantum gravity, including UV/IR mixing, novel modifications of infrared phenomenology that extend effective field theory approaches, and the relaxation of the usual notions of locality. We discuss the relevance of such concepts in quantum gravity for quantum information science, cosmology and general quantum gravity phenomenology.
