My research interests lie in the field of quantum field theory and exactly solvable models. My research focuses on the properties of nonperturbative field effects in M-theory. These are primarily based on realizations of U-duality in its various string-brane interaction systems.
My current research focuses on studying such effects in approximations of the field dynamics of (super-)gravity and DBI-WZ field theories using covariant methods of Generalized Geometry. Building on previous research, various realizations of U-duality—generalized Yang-Baxter deformations—are explored within the Dual and Exceptional Field Theories approach. The polyvectors defining these deformations alter the isometry structure of the deformable vacuum of M-theory, which consequently alters the vertex structure of excitations above it. These effects are tracked both in terms of changes in holographic renormalization-group fluxes and in terms of changes in the spectrum and observable dual theories within the general correspondence between gravitational and gauge field theories.
Key results include a general approach to generating M-theory vacua with fluxes corresponding to the "sedimentation" of dynamical objects or the formation of their bound states.
