Research-oriented Project

Abstract The MIRACLS experiment at the ISOLDE facility at CERN seeks to overcome the sensitivity limit of conventional Collinear Laser Spectroscopy of short-lived radionuclides by extending the laser-ion interaction time by trapping ions of exotic isotopes in a Multi-Reflection Time-of-Flight devic...

Simulation of X-ray spectra of astrophysical sources in the laboratory Laboratory measurements in support of X-ray astrophysics Energetic processes in astrophysical objects cause emission of a continuum of X-radiation. Material in the environment of these objects imprints additional spectral lin...

In a research project Johannes Schumann from Physics Advances explored how colloidal quasicrystals can be obtained by tailoring the interactions between the particles. Quasicrystals are well-ordered structures that do not posses any periodicity. Therefore, there is no unit cell and the rotational sy...

Abstract Motivated from considerations in theoretical cosmology about fluctuations in the very early universe, the aim of the project was to investigate the spectrum of the Lewis-Riesenfeld invariant, an invariant of the time-dependent harmonic oscillator Hamiltonian, and to analyse the behaviour o...
