The interplay of strong interactions and magnetic fields gives rise to unusual forms of
superconductivity and magnetism in quantum many-body systems. Here, we present an …

We analyze spin density waves (SDWs) in the Hubbard model on a square lattice within the
framework of inhomogeneous dynamical mean field theory (IDMFT). Doping the half-filled …

We propose an experimental scheme to favor both the realization and the detection of the
Néel state in a two-component gas of ultracold fermions in a three-dimensional simple-cubic …

To analyze the physical properties arising from indirect magnetic exchange between several
magnetic adatoms and between complex magnetic nanostructures on metallic surfaces, the …

The properties of a phase at finite interactions can be significantly influenced by the
underlying dispersion of the noninteracting Hamiltonian. We demonstrate this by studying …

We investigate exotic paired states of spin-imbalanced Fermi gases in anisotropic lattices,
tuning the dimension between one and three. We calculate the finite temperature phase …

We study magnetic phases of two-component mixtures of ultracold fermions with repulsive
interactions in optical lattices in the presence of both hopping and population imbalance by …

We present a full phase diagram for the one-dimensional (1D) to three-dimensional (3D)
crossover of the Fulde-Ferrell–Larkin-Ovchinnikov (FFLO) state in an attractive Hubbard …

We address the steady-state behavior of a system consisting of several correlated
monoatomic layers sandwiched between two metallic leads under the influence of a bias …

The fermionic, time-reversal-invariant Hofstadter-Hubbard model with a population
difference between the two spin states is investigated. In the strongly interacting regime …
