The influence of the binding energy on Compton-scattering-driven ionization

N. Melzer, M. Kircher, G. Kastirke +31

We present a comprehensive study of Compton scattering of 20 keV photons by bound electrons over a wide range of binding energies (Ne 2p, Ne 2s, C 1s, O 1s, and Ne 1s orbitals). In…

A Cryogenic Penning Trap Based on Permanent Magnets

F. Völksen, K. K. Anjum, R. P. Czampiel +30

We report on a Penning trap based on NdFeB permanent magnets operated at 4\,K with a magnetic field strength of 280\,mT. Reliable loading and confinement of protons, H ions,…

What if active and passive gravitational masses were not equal?

Domenico Giulini

At first glance, combining Newton's laws of motion with his law of gravitation seems straightforward. Students learn to distinguish inertial from gravitational mass and that their…

Corrigendum to "Nonsymplectic automorphisms of prime order on O'Grady's sixfolds"

Annalisa Grossi, Stevell Muller

In this short note we correct the lattice theoretic classification in [Rev. Mat. Iberoam. 38 (2022), no. 4, 1199--1218] of the first named author, including some missing cases and…

Universality in the Transition from Inspiral to Plunge for Extreme-Mass-Ratio-Inspirals: High-Accuracy Analytic Solutions and Catastrophe Theory

Ariadna Ribes Metidieri, Béatrice Bonga, Badri Krishnan +1

We revisit the transition from inspiral to plunge for extreme mass-ratio inspirals on quasi-circular, inclined orbits in Kerr spacetime from the perspective of catastrophe theory.…

Chaotic spin dynamics of elongated spinor condensates

Jose Reyes-Calderón, Albert Gallemí, Carsten Klempt +1

Elongated spin- condensates present a highly non-trivial local magnetization dynamics, due to the interplay between nonlinear and quantum effects stemming from the inhomogeneous…
