Quantum Sensors in Diamond for Nano- and Microscale Magnetic Resonance Applications

Nitrogen vacancy (NV) point defects in diamond have emerged as a promising platform for quantum sensing. The electronic spin state of these solid-state qubits can be optically polarised, coherently manipulated with microwave pulses, and read out via their spin-state-dependent photoluminescence. Using this optically detected magnetic resonance method, magnetic signals from a single molecules or spins can be detected. [more]

Spin Effects in Adsorbed Molecules

  • PC Department Seminar
  • Date: May 16, 2024
  • Time: 02:00 PM (Local Time Germany)
  • Speaker: Richard Berndt
  • Institut für Experimentelle und Angewandte Physik, Christian-Albrechts-Universität zu Kiel
  • Location: Building G
  • Room: 2.06
  • Host: Akitoshi Shiotari
Using low-temperature scanning tunneling microscopy and occasionally synchrotron radiation methods we investigate molecules at surfaces. The experiments along with model calculations reveal molecular spin states and electron transport properties as well as intermolecular interactions. [more]

Low energy electron emission from charge exchange of slow highly charged ions with solid surfaces

The interaction of slow ions with condensed matter leads to the emission of electrons with energies typically well below 20eV. [more]

Homogeneous Bose gases driven far from thermal equilibrium

Far-from-equilibrium systems are ubiquitous in nature, such as in glasses, active matter, and turbulence, but are still poorly understood when compared to the unifying description of thermodynamics for systems in thermal equilibrium. [more]

From BayBE Steps to Giant Leaps - Industrial Applications of Modern Bayesian Optimization

Bayesian optimization is an old technique revived by using machine learning models at its core. This enables a plethora of extensions that really make the technique a great match for several real world applications. We showcase several examples such as custom and chemical encodings, transfer learning and slot-based mixture modelling enabled by our open-source code BayBE (https://github.com/emdgroup/baybe).

Tabletop transient NEXAFS spectroscopy with a laser-produced plasma source

Laboratory-based laser-produced plasma (lpp) soft X-ray sources achieve high brightness and stability in the EUV and XUV range. With emission energies beyond 1.6 keV and stable operating times in the range of hours, they already offer numerous experimental possibilities that are independent and supplemental to investigations at large scale facilities.

Elucidation and Control of Advanced Photofunctions based on Excited States in Molecular Materials

Microscopic understanding of exciton physics in molecular materials for optoelectronics is a great challenge because of their complexity resulting from strong electron-phonon coupling and perhaps interaction to spin degree of freedom, electron spin-flip of intersystem crossing in molecular optoelectronic materials are strongly connected to molecular geometries in the excited states and vibronic coupling, and singlet fission, ultrafast generation of a correlated triplet pair state from a singlet excited state, is viewed as an extreme example of a concerted process of electron-phonon-spin degrees of freedom.
