    "abstract": "We investigate the feasibility of simulating different model Hamiltonians\nused in high-temperature superconductivity. We briefly discuss the most common\nmodels and then focus on the simulation of the so-called t-J-U Hamiltonian\nusing ultra-cold atoms in optical lattices. For this purpose, previous\nsimulation schemes to realize the spin interaction term J are extended. We\nespecially overcome the condition of a filling factor of exactly one, which\notherwise would restrict the phase of the simulated system to a Mott-insulator.\nUsing ultra-cold atoms in optical lattices allows simulation of the discussed\nmodels for a very wide range of parameters. The time needed to simulate the\nHamiltonian is estimated and the accuracy of the simulation process is\nnumerically investigated for small systems.",
