Area of Science:

  • Theoretical Physics
  • High-Energy Physics
  • Condensed Matter Physics

Background:

  • Topological field configurations are crucial in understanding fundamental forces.
  • Yang-Mills gauge theories in higher dimensions present unique theoretical challenges.
  • Compactification techniques are used to relate theories in different dimensionalities.

Purpose of the Study:

  • To investigate the behavior of topological monopole-like field configurations when a higher dimension is compactified.
  • To identify novel solutions emerging in the low-energy effective theory after dimensional reduction.
  • To explore the transformation of these solutions under spontaneous symmetry breaking.

Main Methods:

  • Analysis of topological monopole solutions in 4+1 dimensional Yang-Mills theory.
  • Compactification of the extra dimension with periodic lattice boundary conditions.
  • Investigation of the low-energy effective theory and spontaneous symmetry breaking phenomena.

Main Results:

  • A topological monopole-like field configuration in 4+1 dimensions was identified.
  • Upon compactification to 3+1 dimensions, these configurations manifest as gauged-bosonic Skyrmions.
  • Spontaneous breaking of the low-energy theory leads to the transformation of gauged-bosonic Skyrmions into 't Hooft-Polyakov monopoles.

Conclusions:

  • Dimensional compactification of topological monopoles yields novel gauged-bosonic Skyrmion solutions.
  • Spontaneous symmetry breaking plays a key role in the transition from Skyrmions to 't Hooft-Polyakov monopoles.
  • This study bridges concepts from topological field theory and particle physics phenomenology.
