  • 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 Gitter-QCD ist die etablierte Methode für theoretische Berechnungen zur starken Wechselwirkung jenseits der Störungstheorie. Um qualitative Resultate zu erhalten, werden aufwendige Monte-Carlo-Simulationen durchgeführt. Die Gitter-QCD hat sich in ...

    Financer: DFG: Sonderforschungsbereich

    Die Anti-de Sitter/Conformal Field Theory-Korrespondenz verbindet Gravitationstheorien, die mit differentialgeometrischen Methoden behandelt werden können, mit Quantenfeldtheorien und der Struktur der Elementarteilchen. In diesem Projekt soll diese w ...

  • CRC 647/1: Evolution of Geometrical Structures in Classical and Quantum Cosmology (SP B05)

    Plefka, Jan, Prof. Dr. (Collaborative Research Centre 555 'Complex Non-linear Processes')

    Duration of Project: 10/2006 - 12/2008

    Financer: DFG: Sonderforschungsbereich

    In dem Projekt soll das Zusammenspiel zwischen String-Theorie, Schleifen-Quanten-Gravitation und kosmologischer Feldtheorie untersucht werden. Dabei spielen verschiedene Fragestellungen eine Rolle, die sowohl von der klassischen wie von der Quanten-S ...

  • CRC 647/2–3: Integrable Structures in the Gauge/String Theory Correspondence (SP B08/C05)

    Plefka, Jan, Prof. Dr. (Theoretical Physics / Quantum Field Theory beyond the Standard Model and String Theory)

    Duration of Project: 01/2009 - 12/2016

    Financer: DFG: Sonderforschungsbereich

    Establishing dualities between string and gauge theories is considered to be one of the most important directions of research in mathematical physics. Recent years have seen key advances in uncovering exactly integrable observables in the most promin ...

  • CRC 647/2–3: Tests and Applications of the AdS/CFT Correspondence (SP A08/C06)

    Plefka, Jan, Prof. Dr. (Theoretical Physics / Quantum Field Theory beyond the Standard Model and String Theory)

    Duration of Project: 01/2009 - 12/2016

    Financer: DFG: Sonderforschungsbereich

    The project is devoted to tests and applications of the correspondence between gauge field theories and string theories (AdS/CFT). The main emphasis will be on the following topics: Analysis of new relations between strings and observable quantities ...

  • DAAD PRIME Fellowship: Johannes Thürigen (2016–2018)

    Kreimer, Dirk, Prof. (Theoretical Physics / Mathematical Physics)

    Duration of Project: 09/2016 - 06/2018

    Financer: DAAD
  • DFG Research Grant: Efficient Quasi Monte Carlo Methods and Their Application in Quantum Field Theory

    Tischendorf, Caren, Prof. Dr. (Applied Mathematics)

    Duration of Project: 01/2014 - 12/2016

    Financer: DFG: Sachbeihilfe

    The 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 effective-dimension reduction techniques based on derivati ...

  • DFG Research Grant: Gauge Dependence and Dyson-Schwinger Equations

    Kreimer, Dirk, Prof. (Theoretical Physics / Mathematical Physics)

    Duration of Project: 10/2017 - 12/2019

    Financer: DFG: Sachbeihilfe

    For 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: Sachbeihilfe

    Our 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 space-time 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 ...
