Monopole operators play an important role in the dynamics of three-dimensional conformal field theories. In this talk, I will explain how to use the 1/N_f expansion to study these operators at the infrared fixed points of non-Abelian gauge theories...

In planar N=4 Super-Yang-Mills theory there is a map between gluons scattering amplitudes and null polygonal Wilson loops. This remarkable duality allows one to make an important step forward by Operator-Product-Expanding the scattering amplitudes...

In this talk I will discuss the problem of counting 1/16 BPS operators in N=4 Super-Yang-Mills theory at weak coupling. I will present the complete set of 1/16 BPS operators in the infinite N limit, which agrees with the counting of free BPS multi...

Long-range entangled qubits (or quantum spins) from new states of matter whose low energy effective theory realize topological quantum field theories. Those topologically ordered states of purely bosonic qubits can produce emergent gauge theory and...

AdS/CFT is a duality relating the degrees of freedom in a D dimensional bulk gravity theory to a (D-1) dimensional theory living on the boundary.
I will argue that in fact the boundary theory contains only a subset of the bulk observables. For each...
