Description
Infrared (IR) dualities are an interesting phenomenon that can characterize the low energy dynamics of a quantum field theory. A key question is whether an organizing principle exists for known IR dualities. One approach is identifying a fundamental set of dualities from which others can be derived, often through a process called "deconfinement" when tensor matter fields are involved. In this talk, I will review the idea of the deconfinement and present recent results on how to use it to derive some Kutasov–Schwimmer-like dualities in 3d and 4d. These are dualities for theories involving a U(N) adjoint field in 3d or a USp(2N) antisymmetric field in 4d with superpotential W=A^{p+1}, for which a derivation was previously unknown and many of the standard tests present complications.
