    Flavour-selective localization in interacting lattice fermions

    A large repulsion between particles in a quantum system can lead to their localization, an effect responsible for the Mott insulator phases in strongly correlated materials. In a system with multiple orbitals,...

    Mottness at finite do** and charge instabilities in cuprates

    The influence of Mott physics on the do**–temperature phase diagram of copper oxides represents a major issue that is the subject of intense theoretical and experimental efforts. Here, we investigate the ult...

    Snapshots of the retarded interaction of charge carriers with ultrafast fluctuations in cuprates

    One of the pivotal questions in the physics of high-temperature superconductors is whether the low-energy dynamics of the charge carriers is mediated by bosons with a characteristic timescale. This issue has r...

    Phonon softening and dispersion in the 1D Holstein model of spinless fermions

    We investigate the effect of electron-phonon interaction on the phononic properties in the one-dimensional half-filled Holstein model of spinless fermions. By means of determinantal Quantum Monte Carlo simula...

    Stabilization of A-type layered antiferromagnetic phase in LaMnO3 by cooperative Jahn-Teller deformations

    It is shown that the layered antiferromagnetic order in stoechiometric LaMn03 cannot be understood purely from electronic interactions. On the contrary, it mainly results from strong cooperative Jahn-Teller defor...

    Small polaron formation in many-particle states of the Hubbard-Holstein model: The one-dimensional case

    We investigate polaron formation in a many-electron system in the presence of a local repulsion sufficiently strong to prevent local-bipolaron formation. Specifically, we consider a Hubbard-Holstein model of i...
