Chiral symmetry plays an important role in quantum field theories such as quantum chromodynamics (QCD). Quantum anomalies associated with chiral symmetry are responsible for anomalous transport of Weyl fermions such as the renowned chiral magnetic/vortical effects (CME/CVE). However, one of the crucial ingredients to generate such quantum effects is the chiral imbalance. In heavy ion collisions, which offer a testing ground for anomalous transport in QCD, nontrivial topological excitations of gauge fields may generate a chiral imbalance and thus determine the strength of potential signals in experiments. In condensed matter, the realization of Dirac/Weyl semi-metals as gapless topological phases boosts study of anomalous transport of chiral matter, because the quasiparticles could behave as relativistic fermions with spins and chirality. The relevant theories deepen discussions on the relation between spin chirality, geometric phase, and quantum anomalies.

Another kind of topological materials, the gapped symmetry-protected topological (SPT) phases, including topological insulators and superconductors, have a deep connection to Dirac/Weyl semi-metals and anomalous transport of chiral particles. Gapped SPT phases exhibit exotic and novel quantum phenomena on the boundary of the systems, such as dissipation-free transport and spin-momentum locked surface states. These phenomena are associated with anomalies of more general symmetries, including discrete ones such as the time-reversal symmetry. Like the role of the chiral anomaly in anomalous transport phenomena in chiral matter, a greater understanding of generic symmetry anomalies -- learned from SPT physics -- enables us to study strongly correlated/coupled systems in a more systematic and efficient way. Recent research along this line includes investigations of ground-state properties in condensed matter systems with crystalline symmetries as well as phase diagrams of gauge theories and QCD in various dimensions.

The aim of this workshop is to gather researchers of high-energy and condensed-matter physics working on the related subjects, to exchange ideas and establish collaborations to tackle unsolved issues and carry out future extensions. The workshop expects to welcome 40-60 participants who are interested in the aforementioned topics.
