Orbital mixing as key ingredient for magnetic order in a van der Waals ferromagnet
Recent years have seen a vast increase in research onto van der Waals magnetic materials, due to the richness of many-body effects and the versatility for next-generation technologies. In many of these systems, magnetism is introduced via light 3\textit{d}-transition metal elements, combined with chalcogenides or halogens. Despite the high technological promise in the field of spintronics, the connection between the \textit{d}-wave orbital configuration and the occurrence of low-dimensional mag…

Beyond Linearity and Time-homogeneity: Relational Hyper Event Models with Time-Varying Non-Linear Effects
Recent technological advances have made it easier to collect large and complex networks of time-stamped relational events connecting two or more entities. Relational hyper-event models (RHEMs) aim to explain the dynamics of these events by modeling the event rate as a function of statistics based on past history and external information. However, despite the complexity of the data, most current RHEM approaches still rely on a linearity assumption to model this relationship. In this work, we a…

Negative differential conductance in triangular molecular assemblies
We report the creation and characterization of a molecular-scale negative differential conductance (NDC) device by assembling a triangular trimer of 4,5,9,10-tetrabromo-1,3,6,8-tetraazapyrene (TBTAP) molecules on a superconducting Pb(111) substrate. Using low-temperature scanning tunneling spectroscopy, we observe robust NDC behavior manifesting as a decrease in current with increasing voltage between 0.7-0.9 V arising from the interplay of Coulomb blockade and strong inter-molecular capacitive…

Streit um Steuererhöhungen: CSU-Generalsekretär will bei Wärmepumpen sparen
Finanzminister Klingbeil hat mit seiner Äußerung zu möglichen Steuererhöhungen für Reiche Empörung in der Union ausgelöst. Der Koalitionspartner fordert Einsparungen. CSU-Generalsekretär Huber nahm die Wärmepumpen-Förderung in den Blick.
