First-principles Floquet analysis from real-time propagation
Ruipeng Li, Benshu Fan, Umberto De Giovannini +2
We present a real-time Floquet analysis method for extracting quasi-energies and Floquet states directly from propagated wavefunctions. By reconstructing the one-period evolution o…
Symmetry-Driven Floquet Engineering in Multivalley SnS
Sotirios Fragkos, Benshu Fan, Umberto De Giovannini +5
Coherent interactions between time-periodic electromagnetic fields and materials offer a powerful platform for engineering light-matter hybrid Floquet states with tailored function…
Polarized Houston State Framework for Nonequilibrium Driven Open Quantum Systems
Shunsuke A. Sato, Hannes Hübener, Umberto De Giovannini +1
We introduce a new theoretical framework -- the polarized Houston basis -- to model nonequilibrium dynamics in driven open quantum systems, formulated for use within the quantum ma…
Cavity engineering of solid-state materials without external driving
I-Te Lu, Dongbin Shin, Mark Kamper Svendsen +4
Confining electromagnetic fields inside an optical cavity can enhance the light-matter coupling between quantum materials embedded inside the cavity and the confined photon fields.…
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…
Efficient time dependent Wannier functions for ultrafast dynamics
Cristian M. Le, Hannes Hübener, Ofer Neufeld +1
Time-dependent Wannier functions were initially proposed as a means for calculating the polarization current in crystals driven by external fields. In this work, we present a simpl…
