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…
