Pressure Tuning of Electronic Correlations and Flat Bands in CsCrSb
Maria Chatzieleftheriou, Jonas B. Profe, Ying Li +1
CsCrSb is a newly identified strongly correlated kagome superconductor, characterized by non-Fermi-liquid behavior at elevated temperatures and intertwined charge- and spin…
Orbital-Selective Diffuse Magnetic Fluctuations in SrRuO: a Unified Theoretical Picture
Maria Chatzieleftheriou, Alexander N. Rudenko, Yvan Sidis +2
The quasi-two-dimensional material SrRuO is a paradigmatic example of a correlated system that exhibits unconventional superconductivity and intriguing magnetic properties.…
Interconnected Renormalization of Hubbard Bands and Green's Function Zeros in Mott Insulators Induced by Strong Magnetic Fluctuations
Evgeny A. Stepanov, Maria Chatzieleftheriou, Niklas Wagner +1
We analyze the role of spatial electronic correlations and, in particular, of the magnetic fluctuations in Mott insulators. A half-filled Hubbard model is solved at large strength…
Local and nonlocal electronic correlations at the metal-insulator transition in the Hubbard model in two dimensions
Maria Chatzieleftheriou, Silke Biermann, Evgeny A. Stepanov
Elucidating the physics of the single-orbital Hubbard model in its intermediate coupling regime is a key missing ingredient to our understanding of metal-insulator transitions in r…
Thermodynamic Stability at the Two-Particle Level
A. Kowalski, M. Reitner, L. Del Re +6
We show how the stability conditions for a system of interacting fermions that conventionally involve variations of thermodynamic potentials can be rewritten in terms of one- and t…
Slave-spin mean field for broken-symmetry states: Néel antiferromagnetism and its phase separation in multi-orbital Hubbard models
Matteo Crispino, Maria Chatzieleftheriou, Tommaso Gorni +1
We introduce the generalization of the Slave-Spin Mean-Field method to broken-symmetry phases. Through a variational approach we derive the single-particle energy shift in the mean…
Mott Quantum Critical Points at finite doping
Maria Chatzieleftheriou, Alexander Kowalski, Maja Berović +5
Strongly correlated materials often undergo a Mott metal-insulator transition, which is tipically first-order, as a function of control parameters like pressure. Upon doping, rich…
Enhancement of charge instabilities in Hund's metals by the breaking of rotational symmetry
Maria Chatzieleftheriou, Maja Berović, Pablo Villar Arribi +2
We analyze multi-orbital Hubbard models describing Hund's metals, focusing on the ubiquitous occurrence of a charge instability, signalled by a divergent/negative electronic compre…
