Probing topological Floquet states in graphene with ultrafast terahertz scanning tunneling microscopy
Nils Jacobsen, Michael Schüler, Angel Rubio +3
Floquet control of band topology is a central theme in ultrafast quantum materials science. Established experimental probes of light-induced topological states include ultrafast tr…
A comparative study of perturbative and nonequilibrium Green's function approaches for Floquet sidebands in periodically driven quantum systems
Karun Gadge, Marco Merboldt, Michael Schüler +6
We compare two complementary theoretical approaches to compute and interpret Floquet sidebands in periodically driven quantum materials: a first-order perturbative approach (first-…
Dynamical instability in a Floquet-Driven Dissipative System
Takuya Okugawa, Jens Paaske, Martin Eckstein +3
We analyse the magnon spectrum and distribution function of the antiferromagnetic phase of the Floquet-driven Hubbard model. Above a critical drive strength, we find a dynamical in…
Flexible and Efficient Semi-Empirical DFTB Parameters for Electronic Structure Prediction of 3D, 2D Iodide Perovskites and Heterostructures
Junke Jiang, Tammo van der Heide, Simon Thébaud +11
Density Functional Tight-Binding (DFTB), an approximative approach derived from Density Functional Theory (DFT), has the potential to pave the way for simulations of large periodic…
The 2025 Roadmap to Ultrafast Dynamics: Frontiers of Theoretical and Computational Modelling
Fabio Caruso, Michael A. Sentef, Claudio Attaccalite +27
The exploration of ultrafast phenomena is a frontier of condensed matter research, where the interplay of theory, computation, and experiment is unveiling new opportunities for und…
