Vor 3 Tagen · Abstract. The coexistence of correlated electron and hole crystals enables the realization of quantum excitonic states, capable of hosting counterflow superfluidity and topological orders with ...
Vor 4 Tagen · Niels Henrik David Bohr ( Danish: [ˈne̝ls ˈpoɐ̯ˀ]; 7 October 1885 – 18 November 1962) was a Danish physicist who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922. Bohr was also a philosopher and a promoter of scientific research.
Vor 4 Tagen · Originally called the Rutherford-Bohr atomic model, it is now commonly referred to as Bohr’s atomic model. To understand Bohr’s theory, we must first understand what prior discoveries led him to pursue his revolutionary ideas.

Vor 3 Tagen · Das bohrsche Magneton μ B (nach Niels Bohr) ist der Betrag des magnetischen Moments, das ein Elektron mit der Bahndrehimpulsquantenzahl ℓ = 1 durch seinen Bahndrehimpuls erzeugt. Nach dem ursprünglichen bohrschen Atommodell ist dies der Grundzustand, also der Zustand mit niedrigster Energie. [1]
Vor einem Tag · Elizabeth Wood, Archivist. Photos of the Month. Emilio Segrè Visual Archives. It’s June, which means school is out, parks and beaches are open, and amusement parks are full of screaming children and melting ice cream. For physicists, like many of us, summer means traveling to summer conferences and symposia, visiting friends and colleagues ...
Vor 3 Tagen · James Franck and Gustav Hertz conducted an experiment in 1914, which demonstrated the existence of excited states in mercury atoms. It confirms the prediction of quantum theory that electrons occupy only discrete, quantized energy states. This experiment supports Bohr model of atom.
30. Mai 2024 · Mit Bohranlagen von 6,5 t bis 250 t Zug- und Schubkraft wird in allen Bodenklassen unter Einsatz einer Bohrsuspension eine Pilotbohrung mittels Ortungssystem zielgenau aufgefahren. Mittels eines Backreamers wird in einem oder mehreren Vorgängen die Bohrung aufgeweitet.
