This lecture by Ronnie Rodgers from Nordita explores how holography provides classical gravitational descriptions of strongly coupled quantum field theories. Discover the relationship between holographically dual gravitational theories and QFTs through a specific example involving four-dimensional supersymmetric gauge theory coupled to matter fields (N=4 supersymmetric Yang-Mills theory with N=2 hypermultiplets). Learn about solutions in the dual gravitational theory that break translational symmetry through position-dependent masses for matter fields, and understand how this creates defects at points of vanishing mass in the low-energy QFT. Gain insights into non-perturbative quantum field theory through the lens of holographic principles in this 75-minute presentation from the Dublin Institute for Advanced Studies.
