Fluxbrane in Melvin Background: Membrane Matrix Approach
  We apply the regularized theory of light-cone gauge memberbranes to find the matrix model in the Kaluza-Klein Melvin background. In the static system the Melvin matrix model becomes the BFSS model with two extra mass terms and another term. We solve the equation of motion for simplest N=2 D0 branes system and find that there is a nontrivial configuration. Especially, we also make an ansatz to find the nonstatic solution. The new solution shows that $D_0$ propagating in the magnetic tube field background may expand into a rotating noncommutative ring.
