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…

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.…
