We introduce a new numerical algorithm based on semidefinite programming to efficiently compute bounds on operator dimensions, central charges, and OPE coefficients in 4D conformal and N=1 superconformal field theories. Using our algorithm, we...

Over the past few years, a remarkable duality between planar scattering amplitudes and null polygonal Wilson Loops has emerged in maximally supersymmetric Yang-Mills theory. The duality is now known to hold for arbitrary external helicities and to...

I will discuss the chiral phase transition in a magnetic field at finite temperature and chemical potential within the Sakai-Sugimoto model, a holographic top-down approach to (large-N_c) QCD. For small temperatures the addition of a magnetic field...

The most successful effective theory describing fermions at finite density is Landau's Fermi liquid theory. The theory is basically a free fixed point under the renormalization group flow toward the Fermi surface. The experimental observation of...
