Query: Quantum Lifshitz point in the infinite dimensional Hubbard model   We show that the Gutzwiller variational wave function is surprisingly
accurate for the computation of magnetic phase boundaries in the infinite
dimensional Hubbard model. This allows us to substantially extend known phase
diagrams. For both the half-hypercubic and the hypercubic lattice a large part
of the phase diagram is occupied by an incommensurate phase, intermediate
between the ferromagnetic and the paramagnetic phase. In case of the hypercubic
lattice the three phases join at a new quantum Lifshitz point at which the
order parameter is critical and the stiffness vanishes.
