Physik der kondensierten Materie
Emerging Technologien and innovations in condensed matter physics drive advancements in material properties and applications.

Die Festkörperphysik untersucht die emergenten Eigenschaften von Materie, die aus dem kollektiven Verhalten riesiger Ansammlungen von Atomen und Elektronen in Festkörpern und Flüssigkeiten entstehen. Dieses Forschungsgebiet erforscht Phänomene wie Supraleitung, Magnetismus, Elektronenkorrelation und topologische Phasen und nutzt theoretische Modelle und experimentelle Techniken zur Charakterisierung elektronischer, magnetischer und struktureller Eigenschaften. Die Forschung umfasst Quantenphasenübergänge, niedrigdimensionale Systeme, Spintronik und neuartige Quantenmaterialien und erweitert so das Verständnis fundamentaler Wechselwirkungen und ermöglicht technologische Anwendungen.

Published on 2026-06-26 by Rezvan Tahouri and Jan Marcus Dahlstrm @IOP SCIENCE

Abstract: We study real-time photoionization flux at the Amusia–Cooper minimum (ACM) in argon using ab initio simulations with the relativistic time-dependent configuration-interaction singles (RTDCIS) method in length (LG) and velocity (VG) gauges. A simple analytical model is used to interpret the results, and to construct Wigner delays and Wigner distributions for both gauges and relativistic channels of the photoelectron ( with and ). The two gauges are found to produce qualitatively different ioniz[...]


Our summary: This study investigates ultrafast photoionization in argon at the Amusia–Cooper minimum using RTDCIS simulations.
