Scientific Program

Built around the concepts of boundary and defect in QFT, this Scientific Program will provide a stimulating framework where addressing fundamental questions from a wide spectrum of perspectives. The main scientific goals are to stimulate interactions and cross-field collaborations, and set an agenda for future research in the following main subjects:

Formal/theoretical area:

  • Classification of (super)conformal field theories with boundaries and defects via the classification of (super)conformal boundary conditions.

  • Use of tools like supersymmetry, integrability and conformal bootstrap to constrain and classify QFTs with boundaries and defects.

  • Quantum anomalies in the presence of boundaries and defects and their classification.

  • Dualities between BCFTs and DCFTs in various dimensions.

  • Dimensional flows in the presence of boundary/defect and role of the parent higher dimensional QFT in constraining the lower dimensional BCFT/DCFT.

  • Renormalization Group flows and generalization of c-theorems in the presence of boundaries/defects.

  • Renormalization Group interfaces/domain walls and their selection rules.

  • Role of BCFT/DCFT in string theory and holography to reveal novel phenomena.

Applied area:

  • Classification of topological insulators with the use of BCFT.

  • Novel approaches to the calculation of entanglement entropy using DCFT.

  • Use of DCFT to reveal the phase diagram of dense QCD with heavy quark impurities.

  • Applications of c-theorems of BCFT/DCFT to experimental systems.

  • Investigation of promising novel applications (ex: graphene, topological insulators).
