"The concept of symmetry is without doubt the most significant centerpiece of modern science. Our\r\ncurrent understanding of the visible universe is phrased into a basic set of equations describing what\r\nwe call 'gauge theories'. The laws governing the dynamics of nature have been derived studying the symmetry properties of\r\nthese equations, that is their invariance or non-invariance under certain symmetry 'transformations'. Because of their grand success and while seeming omnipotent, it came\r\nas a sensational surprise, that nature mysteriously does not obey some of the above symmetry principles by mechanisms that are elusive: Quantum Anomalies. The intriguing feature of the anomalous violation of symmetries \r\nis that it cannot be understood by the defining set of equations that were postulated to comprise the physical content of nature, but rather from the structures of quantum theories itself. Quantum anomalies \r\nemerge from the transition from the classical to the quantum level of nature, and researchers have realized that the properties of the physical vacuum (that is the quantum equivalent of 'nothing') are very non-trivial.\r\n\r\nSymmetries are the cornerstones of gauge theories and the fundamental forces they describe. The vast majority of visible matter is governed by the strong interactions, formulated through the theory of Quantum Chromodynamics (QCD). \r\nIn this context, symmetry principles also dictate the existence of another mysterious concept: topology.\r\nTopology is the principle used to describe the fundamental structure of an object, \r\ninvariant under a certain transformation. In physics it describes the\r\ninvariance of the aforementioned basic set of equations under continuous and hence structure-preserving manipulations. It is very suggestive that quantum anomalies and the concept of topology should be intimately related and in fact this assertion is\r\nmost famously confirmed by the so-called axial anomaly.\r\n\r\nThe physics of quantum anomalies and topology is intriguing and often mysterious, yet central to many of the fundamental mechanisms of nature.\r\nAs the anomalous violation of classical symmetries in the earliest stages of the universe is conjectured to be responsible for the dominance\r\nof matter over anti-matter, researchers attempt to recreate the dynamics of matter under extreme conditions at heavy ion collider experiments and thus understand\r\nthese challenging mechanisms. In the early universe as well as in present day experiments the emergence of quantum anomalies is tied to \\textit{out-of-equilibrium} systems.\r\n\r\nIn this thesis we focus on a comprehensive attempt at establishing the theoretical foundations of the non-equilibrium description of anomalous and topological\r\ndynamics. To this end we present a selection of different techniques and approximation schemes, which are motivated by the properties of the space-time evolution\r\nof QCD matter in ultra-relativistic heavy ion collisions. Most importantly we aim to illustrate that the techniques, which are presented here, are applicable to\r\na number of systems in nature, starting from strong-field laser physics to cosmology. The nature of topological effects is much richer in out-of-equilibrium systems\r\nand in accord with present progress in the experimental study of anomalous effects, we hope to contribute to the establishment of a novel view on anomalies\r\nand topology beyond the previous equilibrium paradigm."^^ .
