The symposium aims at bringing together experts on the topics of variational and nonperturbative methods in quantum field theory, topological and conformal field theory, and quantum entanglement in QFT. Those topics have recently experienced a revival of interest due to advances made in the field of quantum computing and quantum entanglement theory. Area laws and entanglement Hamiltonians have opened up a new window into the structure of quantum correlations in strongly correlated systems, and led to a revisit of the variational principle for quantum field theories in the form of quantum tensor networks. Dualities, as symbolized in the picture of Magritte above, and nonlocal symmetries are proving to be manifestations of emerging order in the entanglement structure, and tensor networks provide representations for the underlying tensor fusion categories. The main purpose of this conference is to bring together the different communities that have been working on the many theoretical aspects of this program.
