Exacting N=4 Superconformal Symmetry
Till Bargheer, Niklas Beisert, Wellington Galleas +2
Tree level scattering amplitudes in N=4 super Yang-Mills theory are almost, but not exactly invariant under the free action of the N=4 superconformal algebra. What causes the non-i…

Long-Range Deformations for Integrable Spin Chains
Till Bargheer, Niklas Beisert, Florian Loebbert
We present a recursion relation for the explicit construction of integrable spin chain Hamiltonians with long-range interactions. Based on arbitrary short-range (e.g. nearest-neigh…
