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...

We construct all supergravity theories that can be obtained through factorized projections of N = 8 supergravity, exposing their double-copy structure, and calculate their one-loop four-point scattering amplitudes. We derive representations of gluon...
