Ground States of Fermionic lattice Hamiltonians with Permutation Symmetry
Christina V. Kraus, Maciej Lewenstein, J. Ignacio Cirac
We study the ground states of lattice Hamiltonians that are invariant under permutations, in the limit where the number of lattice sites, N -> \infty. For spin systems, these are p…
Generalized Hartree-Fock Theory for Interacting Fermions in Lattices: Numerical Methods
Christina V. Kraus, J. Ignacio Cirac
We present numerical methods to solve the Generalized Hartree-Fock theory for fermionic systems in lattices, both in thermal equilibrium and out of equilibrium. Specifically, we sh…
Pairing in fermionic systems: A quantum information perspective
Christina V. Kraus, Michael M. Wolf, J. Ignacio Cirac +1
The notion of "paired" fermions is central to important condensed matter phenomena such as superconductivity and superfluidity. While the concept is widely used and its physical me…
