  • 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 ...

  • 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 ...

  • DFG Temporary Position/3: Gauge/String Theory Duality and Integrable Systems

    Eden, Burkhard, Dr. (Mathematical Physics of Space, Time and Matter)

    Duration of Project: 10/2016 - 09/2018

    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 so-called 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 ...

  • DFG Temporary Position: New Perspectives in Strongly Interacting Systems: Preparing for Quantum Gauge Simulators

    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 first-principles study of the non-perturbative 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 ...
