Strongly coupled systems comprise some of the most difficult and important problems in physics. Boundaries, impurities, and defects play a ubiquitous role in understanding their universal behavior, from topological states of matter to confinement in gauge theories. Topologically protected gapless edge modes give rise to remarkable quantized transport, while confining properties of strong interactions are sharply formulated in terms of Wilson and 't Hooft loops.

QFT techniques are routinely applied to systems with boundaries and defects, often with remarkable success. However, in systems with strong interactions many of the important questions remain intractable. Luckily, the rapid development of novel approaches to strongly-interacting QFTs opens a new avenue to study boundaries, defects and impurities. Prominent examples include the Anti-de-Sitter/Conformal Field Theory correspondence and holographic duality, integrability, the conformal bootstrap, non-perturbative supersymmetry methods, the use of entanglement entropy and other quantum information measures, anomalies and higher-form symmetries, hydrodynamics of QFTs, and more.

The goal of the program is to discuss new developments in QFT with boundaries, impurities and defects with focus on

• Holographic duality
• New phases and RG flows with boundaries
• Anomalies and c-theorems
• Supersymmetric localization
• Bootstrap methods
• Integrability

Participants will include T. Brennan, M. Chernodub, L. Di Pietro, M. Frau, Z. Komargodski, M. Metlistki, I. Runkel, J. Russo, F. Parisen Toldin, E. Tonni
