Osmates on the verge of a Hund's-Mott transition: The different fates of NaOsO and LiOsO
Daniel Springer, Bongjae Kim, Peitao Liu +6
We clarify the origin of the strikingly different spectroscopic properties of the chemically similar compounds NaOsO and LiOsO. Our first-principle many-body analysis demon…
Synergy between Hund-driven correlations and boson-mediated Superconductivity
Laura Fanfarillo, Angelo Valli, Massimo Capone
Multiorbital systems such as the iron-based superconductors provide a new avenue to attack the longstanding problem of superconductivity in strongly correlated systems. In this wor…
Quantum fluctuations beyond the Gutzwiller approximation in the Bose-Hubbard model
Fabio Caleffi, Massimo Capone, Chiara Menotti +2
We develop a quantum many-body theory of the Bose-Hubbard model based on the canonical quantization of the action derived from a Gutzwiller mean-field ansatz. Our theory is a syste…
Single-boson exchange decomposition of the vertex function
Friedrich Krien, Angelo Valli, Massimo Capone
We present a decomposition of the two-particle vertex function of the single-band Anderson impurity model which imparts a physical interpretation of the vertex in terms of the exch…
Photoinduced nematic state in FeSeTe
Laura Fanfarillo, Damir Kopić, Andrea Sterzi +8
FeSeTe compounds present a complex phase diagram, ranging from the nematicity of FeSe to the magnetism of FeTe. We focus on FeSeTe, where the…
