Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

Abstract The critical O (N) CFT in spacetime dimensions 2< d< 4 is one of the most important
examples of a conformal field theory, with the Ising CFT at N= 1, 2⩽ d< 4, as a notable …

The interplay between unitary dynamics and local quantum measurements results in
unconventional nonunitary dynamical phases and transitions. In this paper we investigate …

A bstract I study the two-dimensional defects of the d dimensional critical O (N) model and
the defect RG flows between them. By combining the ϵ-expansion around d= 4 and d= 6 as …

We give a detailed account of the theory of position space renormalization using graphical
functions in the case of dimensionally regularized ϕ 4 theory in four dimensions. In this …

The directed bond percolation is a paradigmatic model in nonequilibrium statistical physics.
It captures essential physical information on the nature of continuous phase transition …

Employing the functional renormalization group approach at next-to-leading order of the
derivative expansion, we refine our earlier findings for the location of the Yang-Lee edge …

We perform an all-order resurgence analysis of a quantum field theory renormalon that
contributes to an anomalous dimension in six-dimensional scalar ϕ 3 theory and is …

A bstract Feynman periods are Feynman integrals that do not depend on external
kinematics. Their computation, which is necessary for many applications of quantum field …

We analyze the renormalization group (RG) flows of two effective Lagrangians, one for
measurement-induced transitions of monitored quantum systems and one for entanglement …
