Countability Properties of Weakly Compact Sets in Asymmetric Locally Convex Spaces
Jobst Ziebell
A dual pair formulation for asymmetric locally convex spaces is developed that strictly generalises the ordinary vector space setting. The concept of a polar topology carries over…
Wetterich's Equation and its Boundary Conditions for Radon Measures on Locally Convex Spaces
Jobst Ziebell
Wetterich's equation and corresponding flows of effective average actions are used frequently in theoretical physics to study the properties of quantum field theories. Under approp…
Tikhonov Well-Posedness and Differentiability on Asymmetrically Normed Spaces
Jan Fischer, Jobst Ziebell
On normed vector spaces there is a well-known connection between the Tikhonov well-posedness of a minimisation problem and the differentiability of an associated convex conjugate f…
Existence theorem on the UV limit of Wilsonian RG flows of Feynman measures
Andras Laszlo, Zsigmond Tarcsay, Jobst Ziebell
In nonperturbative formulation of Euclidean signature quantum field theory (QFT), the vacuum state is characterized by the Wilsonian renormalization group (RG) flow of Feynman meas…
-splitting Densities and Reflection Positivity
Jobst Ziebell
A simple condition is given that is sufficient to determine whether a measure that is absolutely continuous with respect to a Gaußian measure on the space of distributions is refle…
Pauli-Term-Induced Fixed Points in -dimensional QED
Holger Gies, Kevin K. K. Tam, Jobst Ziebell
We explore the fixed-point structure of QED-like theories upon the inclusion of a Pauli spin-field coupling. We concentrate on the fate of UV-stable fixed points recently discovere…
Super-Gaussian Decay of Exponentials: A Sufficient Condition
Benjamin Hinrichs, Daan Willem Janssen, Jobst Ziebell
In this article, we present a sufficient condition for the exponential to have a tail decay stronger than any Gaussian, where is defined on a locally convex space…
A Rigorous Derivation of the Functional Renormalisation Group Equation
Jobst Ziebell
The functional renormalisation group equation is derived in a mathematically rigorous fashion in a framework suitable for the Osterwalder-Schrader formulation of quantum field theo…
Existence and Construction of Exact FRG Flows of a UV-Interacting Scalar Field Theory
Jobst Ziebell
We prove the existence and give a construction procedure of Euclidean-invariant exact solutions to the Wetterich equation in dimensions satisfying the naive boundary condit…
Asymptotically Safe QED
Holger Gies, Jobst Ziebell
High-energy completeness of quantum electrodynamics (QED) can be induced by an interacting ultraviolet fixed point of the renormalization flow. We provide evidence for the existenc…
FlexibleSUSY: Precise automated calculations in any BSM theory
Peter Athron, Markus Bach, Dylan Harries +7
FlexibleSUSY is a software package for various calculations in any model of physics beyond the standard model (not just any supersymmetric model). FlexibleSUSY can solve boundary v…
FlexibleSUSY 2.0: Extensions to investigate the phenomenology of SUSY and non-SUSY models
Peter Athron, Markus Bach, Dylan Harries +5
We document major new features and improvements of FlexibleSUSY, a Mathematica and C++ package with a dependency on the external package SARAH, that generates fast and precise spec…
