Ultrafast nonlinear Hall effect in black phosphorus
Maciej Dendzik, Andrea Marini, Samuel Beaulieu +9
The nonlinear Hall effect (NHE) is a recently discovered member of the Hall effect family in which the Hall voltage shows a nonlinear behavior when a transverse electric field is a…
Ultrafast Formation and Annihilation of Strongly Bound, Anisotropic Excitons
Lawson T. Lloyd, Tommaso Pincelli, Mohamed Amine Wahada +12
Van der Waals (vdW) layered materials with long-range magnetic order have the potential to enable novel optoelectronic and spintronic applications. Among these, CrSBr is an air-sta…
pynxtools: A Python framework for generating and validating NeXus files in experimental data workflows
Sherjeel Shabih, Lukas Pielsticker, Florian Dobener +19
Scientific data across physics, materials science, and materials engineering often lacks adherence to FAIR principles (Barker et al., 2022; Jacobsen et al., 2020; M. D. Wilkinson e…
Orbital mixing and strong Hund's coupling stabilize spin order in van der Waals ferromagnet CrI3
Alessandro De Vita, Srdjan Stavrić, Roberto Sant +8
Recent years have seen a vast increase in research into van der Waals magnetic materials. In many of these systems, magnetism is introduced via light 3d-transition metal elements,…
Ultrafast demagnetization dynamics of 4f antiferromagnets
Maryna Pankratova, Vladislav Borisov, Danny Thonig +6
We study the ultrafast demagnetization dynamics of LnRhSi (Ln Pr, Nd, Sm, Gd, Tb, Dy, Ho) antiferromagnets (AFM) after excitation by a laser pulse, using a combination…
The 2025 Roadmap to Ultrafast Dynamics: Frontiers of Theoretical and Computational Modelling

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…
Frontier orbitals control dynamical disorder in molecular semiconductors
Alexander Neef, Sebastian Hammer, Yuxuan Yao +11
Charge transport in organic semiconductors is limited by dynamical disorder. Design rules for new high-mobility materials have therefore focused on limiting its two foundations: st…
Coherent Light Control of a Metastable Hidden Phase
J. Maklar, S. Dong, J. Sarkar +13
Metastable phases present a promising route to expand the functionality of complex materials. Of particular interest are light-induced metastable phases that are inaccessible under…
Orbital-resolved Observation of Singlet Fission
Alexander Neef, Samuel Beaulieu, Sebastian Hammer +8
Singlet fission may boost photovoltaic efficiency [by transforming a singlet exciton into two triplet excitons and thereby doubling the number of excited charge carriers. The prima…
Unveiling the Orbital Texture of 1T-TiTe using Intrinsic Linear Dichroism in Multidimensional Photoemission Spectroscopy
Samuel Beaulieu, Michael Schüler, Jakub Schusser +9
The momentum-dependent orbital character in crystalline solids, referred to as orbital texture, is of capital importance in the emergence of symmetry-broken collective phases such…
Nonequilibrium Charge-Density-Wave Order Beyond the Thermal Limit
J. Maklar, Y. W. Windsor, C. W. Nicholson +17
The interaction of many-body systems with intense light pulses may lead to novel emergent phenomena far from equilibrium. Recent discoveries, such as the optical enhancement of the…
