  1. Disentangling real space fluctuations: The diagnostics of metal-insulator transitions beyond single-particle spectral functions

    Publication
    The destruction of metallicity due to the mutual Coulomb interaction of quasiparticles gives rise to fascinating phenomena of solid state physics such as the Mott metal-insulator transition …

  2. CTSEG: A segment picture quantum impurity solver based on TRIQS

    Publication
    Electron-electron interactions are a key determinant of the electrical and optical response properties in solid-state materials. Yet, the many-electron problem is outstandingly difficult, and can …

  3. Discrete Lehmann representation of three-point functions

    Publication
    We present a generalization of the discrete Lehmann representation (DLR) to three-point correlation and vertex functions in imaginary time and Matsubara frequency. The representation takes the form …

  10. Tracking the Footprints of Spin Fluctuations: A Multi-Method, Multi-Messenger Study of the Two-Dimensional Hubbard Model

    Publication
    The Hubbard model represents the fundamental model for interacting quantum systems and electronic correlations. Using the two-dimensional half-filled Hubbard model at weak coupling as testing grounds …

  11. Planckian Metal at a Doping-Induced Quantum Critical Point

    Publication
    We numerically study a model of interacting spin-\(1/2\) electrons with random exchange coupling on a fully connected lattice. This model hosts a quantum critical point separating …

    Publication

  13. Magnetic response of Sr2RuO4: quasi-local spin fluctuations due to Hund's coupling

    Publication
    We study the magnetic susceptibility in the normal state of Sr2RuO4 using dynamical mean-field theory including dynamical vertex corrections. Besides the well known incommensurate response, our calculations …
