Phys. Rev. Lett. 104, 240406 (2010) [4 pages]η Condensate of Fermionic Atom Pairs via Adiabatic State PreparationReceived 6 November 2009; published 18 June 2010 We discuss how an η condensate, corresponding to an exact excited eigenstate of the Fermi-Hubbard model, can be produced with cold atoms in an optical lattice. Using time-dependent density matrix renormalization group methods, we analyze a state preparation scheme beginning from a band insulator state in an optical superlattice. This state can act as an important test case, both for adiabatic preparation methods and the implementation of the many-body Hamiltonian, and measurements on the final state can be used to help detect associated errors. © 2010 The American Physical Society URL:
