Description
Emergent topological objects are known to play a fundamental role in the QCD nonperturbative phenomena such as confinement and chiral symmetry breaking. Examples include the family of instantons (vacuum instantons, calorons at finite temperature, as well as instantons with nontrivial holonomy), the sphalerons, and the chromo-magnetic monopoles. This talk will focus on discussing possible experimental evidences for such topological components of QCD and QGP in heavy-ion collisions. The instantons and sphalerons can induce nonzero axial charges through triangle anomaly, which in turn lead to detectable signatures via the chiral magnetic effect (CME). We will discuss the present status and future prospects for the search of CME. The chromo-magnetic monopoles, on the other hand, are crucial for understanding the experimentally observed properties of quark-gluon plasma (QGP). We will demonstrate how such a magnetic component is crucial for understanding such empirical data from heavy-ion collisions.
