Understanding gauge field dynamics at the non-perturbative level, in Quantum Chromodynamics (QCD) has been a persistent challenge. Lattice gauge theories solve these issues from first principles, on supercomputers. Semiclassical methods rely on dynamics of gluonic solitons – instantons, monopoles, instanton-dyons – to model various QCD phase transitions. Sphaleron explosions and phenomena related to hiral anomaly are important for phenomena in heavy ion collisions and cosmology. The QCD strings are effective objects related to confinement. Their dynamics is essential for the understanding of hadronic spectroscopy and Regge phenomenology. QCD strings are also naturally present in holographic models based on the AdS/CFT correspondence, and used successfully to model hadronic spectra and matter properties.
