Quantum Mechanics of Lowest Landau Level Derived from N= 4
... In the present paper, we consider N = 4 SYM on a sphere with the chemical potential, µ, and show that the states of the low energy effective theory with µ ∼ 1 are the half-BPS states. This gives a clear physical picture of the decoupling limit that isolates the half-BPS states from other states of t ...

A Weak Gravity Conjecture for Scalar Field Theories
... This accounts for the name “weak/strong gravity”. The calculation above tells us that kink solutions appear in weak gravity limit √gG ≫ 1 but disappear in strong gravity limit √gG ≪ 1. In the absence of gravity, the existence of soliton is dictated by unitarity. Naturally we expect that unitarity wi ...

This leads to what is known as “dissipationless” transport by the edge states – no electrons scatter and so no energy is lost as heat – and is ultimately responsible for the precise quantized t ...
