Computation of string loop corrections to the effective action has been one of the main challenges in string phenomenology.
Quantum systems that describe black holes are expected to have a chaotic spectrum. This means the statistics of nearby energy levels share some common features with random matrix ensembles.
We derive a crossing equation that acts only on the scalar primary operators of any 2d CFT with U(1)^c symmetry. We derive bounds on the scalar gap of all such theories.
The Hungarian physicist Eugene Wigner introduced random matrix models in physics to describe the energy spectra of atomic nuclei.
We discuss a mechanism which dynamically adjusts cosmological constant toward 0+. The adjustment is quantum-mechanical, discharging cosmological constant in random discrete steps.…
The supersymmetric index of N=4 SU(N) Super Yang-Mills is a well studied quantity.
