Between Dec 19, 2024 and Jan 2, 2025, datasets can be submitted to DRUM but will not be processed until after the break. Staff will not be available to answer email during this period, and will not be able to provide DOIs until after Jan 2. If you are in need of a DOI during this period, consider Dryad or OpenICPSR. Submission responses to the UDC may also be delayed during this time.

    Geometry and Dynamics of a Coupled 2D and 4D Quantum Field Theory
    (2016-05-12) Konishi, Kenichi
    Geometric and dynamical aspects of a coupled 4D-2D interacting quantum field theory - the gauged nonAbelian vortex will be discussed. The fluctuations of the internal 2D nonAbelian vortex zeromodes excite the massless 4D Yang-Mills modes, which give rise to divergent energies. This means that the well-known 2D CP(N-1) zeromodes associated with a nonAbelian vortex become nonnormalizable. At the same time, all sorts of global, topological 4D effects such as the nonAbelian Aharonov-Bohm effect come into play. These topological, global features and the dynamical properties of the fluctuations of the 2D vortex moduli are intimately correlated, as shown concretely here in a U(1) xSU(N) x SU(N) model with scalar fields in a bifundamental representation of the two SU(N) factor gauge groups.
