Momentum-Selective Electron and Spin Dynamics under Ultrafast Photoexcitation
Gusein Bedirkhanov, Nagamalleswararao Dasari, Alexander I. Lichtenstein +1
Recent advances in time-resolved spectroscopies have enabled direct access to the momentum-selective nonequilibrium dynamics of correlated quantum materials, revealing a strongly m…
Emergent Topology from Nonlocal Electronic Correlations in One Dimension
Félix Fossati, Erik Linnér, Evgeny A. Stepanov
We demonstrate that electronic correlations in low-dimensional systems can induce topological phases starting from a topologically trivial noninteracting band structure. Using an a…
Non-Fermi-liquid behaviour and Fermi-surface expansion induced by van Hove-driven ferromagnetic fluctuations: the D-TRILEX analysis
Ilia S. Dedov, Andrey A. Katanin, Evgeny A. Stepanov
We consider the electronic and magnetic properties of the Hubbard model on a square lattice with the Fermi level near van Hove singularity and the ratio of the next-nearest-neighbo…
Superconductivity of Bad Fermions: Origin of Two Gaps in HTSC Cuprates
E. A. Stepanov, S. Iskakov, M. I. Katsnelson +1
We investigate the spectral properties of the doped Hubbard model with parameters typical for high-temperature cuprate superconductors. Our approach is based on a novel st…
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.…
Fingerprints of a charge ice state in the doped Mott insulator NbCl
Evgeny A. Stepanov
The interplay between strong electronic correlations and the inherent frustration of certain lattice geometries is a common mechanism for the formation of nontrivial states of matt…
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…
