Algorithms for lattice QCD and related models
Hasenbusch, Martin, (Theoretical Physics / Phenomenology of Elementary Particles beyond the Standard Model)
Duration of Project: 10/2016  09/2018
Financer: DFG: Eigene Stelle (Sachbeihilfe)Die GitterQCD ist die etablierte Methode für theoretische Berechnungen zur starken Wechselwirkung jenseits der Störungstheorie. Um qualitative Resultate zu erhalten, werden aufwendige MonteCarloSimulationen durchgeführt. Die GitterQCD hat sich in ...
DAAD PRIME Fellowship: Johannes Thürigen (2016–2018)

Duration of Project: 09/2016  06/2018
Financer: DAAD
Tischendorf, Caren, Prof. Dr. (Applied Mathematics)
Duration of Project: 01/2014  12/2016
Financer: DFG: SachbeihilfeThe project aims at the exploration of quasi Monte Carlo (QMC) methods for applications in Euclidean quantum field theory and statistical mechanics. We plan to explore and construct efficient effectivedimension reduction techniques based on derivati ...
DFG Research Grant: Gauge Dependence and DysonSchwinger Equations
Kreimer, Dirk, Prof. (Theoretical Physics / Mathematical Physics)
Duration of Project: 10/2017  12/2019
Financer: DFG: SachbeihilfeFor gauge theories in particular we want to clarify the interplay between quantisation and gauge fixing in covariant gauges and the structure of (systems of) Dyson–Schwinger equations (DSE). We want to investigate this in the context of higher dimens ...
DFG Research Grant: Yangian Symmetry in Quantum Gauge Field Theory
Plefka, Jan, Prof. Dr. (Theoretical Physics / Quantum Field Theory beyond the Standard Model and String Theory)
Duration of Project: 01/2017  09/2020
Financer: DFG: SachbeihilfeOur understanding of nature at its deepest level is governed by symmetries. This proposal aims at studying hidden symmetries in quantum field theory going beyond the established spacetime symmetries of the Poincare group and its supersymmetric or co ...
DFG Temporary Position/2: Gauge/String Theory Duality and Integrable Systems
Eden, Burkhard, Dr. (Mathematical Physics of Space, Time and Matter)
Duration of Project: 11/2013  11/2015
Financer: DFG: Eigene Stelle (Sachbeihilfe)In quantum field theory (QFT) in four dimensions calculations can often only be done by perturbation theory w.r.t. the coupling constant. In the case of electromagnetism this is the electric charge which is a very small parameter so that the leading ...

DFG Temporary Position: Integrability and Conformal Symmetry in Four Dimensions
Löbbert, Florian, (Theoretical Physics / Quantum Field Theory beyond the Standard Model and String Theory)
Duration of Project: 10/2019  12/2021
Financer: DFG: Eigene Stelle (Sachbeihilfe)One source of inspiration to tackle the problems of modern quantum field theory comes from the socalled gauge/gravity duality. This conjectured correspondence states that certain highly symmetric quantum field theories in four dimensions have a dual ...
DFG Temporary Position: Integrability in Four Dimensions
Löbbert, Florian, (Theoretical Physics / Quantum Field Theory beyond the Standard Model and String Theory)
Duration of Project: 10/2017  09/2019
Financer: DFG: Eigene Stelle (Sachbeihilfe)Integrable models furnish a fertile arena for studying the theoretical framework that underlies our physical reality. They have a natural home in two dimensions and feature in elegant limits of higher dimensional systems. Notably, integrable models h ...

Banerjee, Debasish, Dr. (Theoretical Physics / Quantum Field Theory beyond the Standard Model and String Theory)
Duration of Project: 08/2018  11/2020
Financer: DFG: Eigene Stelle (Sachbeihilfe)A firstprinciples study of the nonperturbative physics in strongly interacting systems is a challenging field of research. It impacts a wide variety of areas, from new physics beyond the Standard Model of particle physics, to Quantum Chromodynamics ...
