          The Anderson Hamiltonian is used to model particles moving in
	disordered media, it can be thought of as a Schrödiger operator with an
	extremely irregular random potential. Using the recently developed theory of
	"Paracontrolled Distributions" we are able to define the Anderson
	Hamiltonian as a self-adjoint non-positive operator on the 2- and
	3-dimensional torus and give an explicit description of its domain.
	Then we use these results to solve some semi-linear PDEs whose linear part
	is given by the Anderson Hamiltonian, more precisely the multiplicative
	stochastic NLS and nonlinear Wave equation.
	This is joint work with M. Gubinelli and B. Ugurcan.
