The topological structure of field theory often makes inevitable the existence of stable and unstable localised solutions of the field equations. These are minima and saddle points of the energy. Saddle point solutions occurring this way are known as sphalerons, and the most interesting one is in the electroweak theory of coupled W, Z and Higgs bosons. The topological ideas underpinning sphalerons are reviewed here.

  1. Higher-dimensional magnetic Skyrmions

    cond-mat.mes-hall 2024-11 conditional novelty 7.0 of 10

    Three-dimensional magnetic Skyrmions with an S³ target space are proposed, with a generalized DMI yielding a stable Skyrmion, a sphaleron, and a metastable small Skyrmion in the hybrid model.

  2. Quantum-Ordering Ambiguities in Weak Chern-Simons 4D Gravity and Metastability of the Condensate-Induced Inflation

    gr-qc 2024-11 conditional novelty 5.0 of 10

    In a Chern-Simons gravity model, quantum-ordering-dependent imaginary parts of the gravitational anomaly condensate give inflation a finite lifetime and imply the string scale is about one tenth of the Planck mass.
