Decoupling charge and heat transport is essential for optimizing thermoelectric materials. Strategies to inhibit lattice-driven heat transport, however, also compromise carrier mobility, limiting the performance of most thermoelectrics, including Fe$

BMW Agents -- A Framework For Task Automation Through Multi-Agent Collaboration

Autor: Crawford, Noel, Duffy, Edward B., Evazzade, Iman, Foehr, Torsten, Robbins, Gregory, Saha, Debbrata Kumar, Varma, Jiya, Ziolkowski, Marcin

Autonomous agents driven by Large Language Models (LLMs) offer enormous potential for automation. Early proof of this technology can be found in various demonstrations of agents solving complex tasks, interacting with external systems to augment thei

The NA48/2 experiment at CERN reports the first observation of the $K^{\pm} \rightarrow \pi^{0} \pi^{0} \mu^{\pm} \nu$ decay based on a sample of 2437 candidates with 15% background contamination collected in 2003--2004. The decay branching ratio in

Ultrafast Orbital Hall Effect in Metallic Nanoribbons

Autor: Busch, Oliver, Ziolkowski, Franziska, Göbel, Börge, Mertig, Ingrid, Henk, Jürgen

The orbital Hall effect can generate currents of angular momentum more efficiently than the spin Hall effect in most metals. However, so far, it has only been understood as a steady state phenomenon. In this theoretical study, the orbital Hall effect

Ultrafast Dynamics of Orbital Angular Momentum of Electrons Induced by Femtosecond Laser Pulses: Generation and Transfer Across Interfaces

Autor: Busch, Oliver, Ziolkowski, Franziska, Mertig, Ingrid, Henk, Jürgen

The orbital angular momenta (OAM) of electrons play an increasingly important role in ultrafast electron and magnetization dynamics. In this theoretical study, we investigate the electron dynamics induced by femtosecond laser pulses in a normal metal
