Ultrafast dynamics of excitons in black phosphorus
Geoffroy Kremer, Juan F. P. Mosquera, Joël Morf +9
Excitons are key quasiparticles determining the optical properties of solids. As such, they can be utilized to coherently control the electronic structure of materials using optica…
Enhanced Valley Polarization via Nonlinear Cascaded Quantum-Geometric Selection Rules
Quentin Courtade, Sotirios Fragkos, Dominique Descamps +4
The quantum geometric properties of Bloch electrons fundamentally govern light-matter interactions and optical selection rules in solids. In semiconducting transition-metal dichalc…
Direct observation of strain and confinement shaping the hole subbands of Ge quantum wells
Enrico Della Valle, Arianna Nigro, Miki Bonacci +6
Germanium-silicon-germanium (Ge/SiGe) heterostructures have emerged as a promising platform for hole-spin quantum technologies and high-mobility electronics, where st…
Accurate and efficient simulation of photoemission spectroscopy via Kohn-Sham scattering states
Gian Parusa, Sotirios Fragkos, Samuel Beaulieu +1
We introduce an efficient first-principles framework for simulating angle-resolved photoemission spectroscopy (ARPES) based on the direct computation of photoelectron states as sol…
Reexamining Circular Dichroism in Photoemission From a Topological Insulator
Ittai Sidilkover, Yun Yen, Sunil Wilfred D'Souza +10
The orbital angular momentum (OAM) of electron states is an essential ingredient for topological and quantum geometric quantities in solids. For example, Dirac surface states with…
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…
First-principle tight-binding approach to angle-resolved photoemission spectroscopy simulations: importance of light-matter gauge and ubiquitous interference effects
Yun Yen, Gian Parusa, Michael Schüler
Angle-resolved photoemission spectroscopy (ARPES) is one of the most powerful techniques to study the electronic structure of materials. To go beyond the paradigm of band mapping a…
