Off-shell divergences in quantum gravity
Vlad-Mihai Mandric, Tim R. Morris, Dalius Stulga
We investigate off-shell perturbative renormalisation of pure quantum gravity for both background metric and quantum fluctuations. We show that at each new loop order, the divergen…
Universal scaling dimensions for highly irrelevant operators in the Local Potential Approximation
Vlad-Mihai Mandric, Tim R. Morris, Dalius Stulga
We study -dimensional scalar field theory in the Local Potential Approximation of the functional renormalization group. Sturm-Liouville methods allow the eigenoperator equation…
The functional approximation
Tim R. Morris, Dalius Stulga
This article is a review of functional approximations in the asymptotic safety approach to quantum gravity. It mostly focusses on a formulation that uses a non-adaptive cuto…
Provable properties of asymptotic safety in approximation
Alex Mitchell, Tim R. Morris, Dalius Stulga
We study an approximation to asymptotic safety, using a family of non-adaptive cutoffs, kept general to test for universality. Matching solutions on the four-dimensional sph…
Spiral bandwidth of four-wave mixing in Rb vapour
Rachel F. Offer, Dalius Stulga, Erling Riis +2
Laguerre-Gauss beams, and more generally the orbital angular momentum of light (OAM) provide valuable research tools for optical manipulation, processing, imaging and communication…
