    "abstract": "An experiment demonstrating the quantum simulation of a spin-lattice\nHamiltonian is proposed. Dipolar interactions between nuclear spins in a solid\nstate lattice can be modulated by rapid radio-frequency pulses. In this way,\nthe effective Hamiltonian of the system can be brought to the form of an\nantiferromagnetic Heisenberg model with long range interactions. Using a\nsemiconducting material with strong optical properties such as InP, cooling of\nnuclear spins could be achieved by means of optical pumping. An additional\ncooling stage is provided by adiabatic demagnetization in the rotating frame\n(ADRF) down to a nuclear spin temperature at which we expect a phase transition\nfrom a paramagnetic to antiferromagnetic phase. This phase transition could be\nobserved by probing the magnetic susceptibility of the spin-lattice. Our\ncalculations suggest that employing current optical pumping technology,\nobservation of this phase transition is within experimental reach.",
