"Precision Spectroscopy in few-body Atoms and Molecules" (Prof. Frédéric Merkt)

Datum: 16.04.2024
Uhrzeit: 14:30
Vortragende(r): Prof. Frédéric Merkt
ETH Zürich
Ort: Max Planck Institute of Quantum Optics
Raum: Herbert Walther Lecture Hall

Precision measurements of the Rydberg spectra of H, He and H2 will be presented, which aim at determining their ionization energies and, in the case of H2, also the spin-rovibrational energy-level structure of H2+. These measurements are carried out for comparison with the results of first-principles calculations that include the treatment of finite-nuclear-size effects and relativistic and quantum-electrodynamics corrections up to high order in the fine-structure constant.

“Single-spin magnetic resonance using microwave photon counting” (Prof. Patrice Bertet)

Datum: 30.04.2024
Uhrzeit: 14:30
Vortragende(r): Prof. Patrice Bertet
Université Paris-Saclay, Gif-sur-Yvette, France
Ort: Max Planck Institute of Quantum Optics
Raum: Herbert Walther Lecture Hall

Electron Spin Resonance (ESR) spectroscopy characterizes paramagnetic impurities in a sample for chemistry, biology, and material sciences. We have developed a novel ESR detection method that reaches single spin sensitivity, using a microwave photon counter based on a superconducting qubit at millikelvin temperatures. [mehr]
