Projective cooling for the transverse Ising model

Erik J. Gustafson (Department of Physics and Astronomy, The University of Iowa, Iowa City, Iowa 52242, USA)

We demonstrate the feasibility of ground state preparation for the transverse Ising model using projective cooling, and show that the algorithm can effectively construct the ground state in the disordered (paramagnetic) phase. On the other hand, significant temperature effects are encountered in the ordered (ferromagnetic) phase requiring larger lattices to accurately simulate.
