Asymptotic safety is a theoretical proposal for the ultraviolet completion of quantum field theories, in particular for quantum gravity. Significant progress on this program has led to a …
A bstract We perform a bootstrap analysis of a mixed system of four-point functions of bosonic and fermionic operators in parity-preserving 3d CFTs with O (N) global symmetry …
Using large-scale quantum Monte Carlo simulations, we exactly solve a model of fermions hopping on the honeycomb lattice with cluster charge interactions, which has been …

We study the chiral Ising, the chiral XY, and the chiral Heisenberg models at four-loop order with the perturbative renormalization group in 4-ε dimensions and compute critical …
The idea of the conformal bootstrap is to constrain and solve CFTs using physical consistency conditions like symmetry, unitarity, and causality. By relying on nonperturbative …

We explore the phenomenology of scalar fields coupled to asymptotically safe quantum gravity, in light of their potential significance for dark matter, for the inflaton as well as …
A bstract We study the conformal bootstrap for 4-point functions of fermions< ψ i ψ j ψ k ψ ℓ> in parity-preserving 3d CFTs, where ψ i transforms as a vector under an O (N) global …
We investigate the ground state phase diagram of an extended Hubbard model with a π-flux hopping term at half filling on a square lattice, with unbiased large-scale auxiliary-field …
The Abelian Higgs model is the textbook example for the superconducting transition and the Anderson-Higgs mechanism, and has become pivotal in the description of deconfined …
