| contents | Chiral and conformal anomalies are fundamental phenomena that span multiple disciplines, including high-energy physics, condensed matter theory and cosmology. These anomalies play a crucial role in understanding fundamental interactions and manifest themselves through divergences and traces of correlation functions. In this thesis, we investigate these phenomena within the framework of conformal field theory, elucidating their intricate structure and physical implications. Our primary focus is on the role of conformal Ward identities in fully characterizing parity-odd interactions associated with chiral and conformal anomalies in momentum space. Furthermore, we explore mechanisms that lead to the breaking of conformal invariance, such as finite-temperature and finite-density effects or the presence of a fermion mass, and examine how parity-odd anomalous interactions behave under these conditions. By analyzing these phenomena through the lens of conformal and thermal field theories, we obtain deeper insights into their mathematical structure and their significance across a wide range of physical contexts. |
