Open MSc positions in the Loth group

May 20, 2022 /

Join us in the exploration of physics at the atomic scale! The Loth group is inviting students to apply for Master thesis (MSc) projects in quantum nanoscience.

You will directly participate in state-of-the-art research in quantum nanoscience. In addition to conducting fascinating experiments here in Stuttgart, you will have the chance to participate in at least one major conference such as the Spring meeting of the DPG and build contacts in our network of nanoscience research groups around the world for possible stays abroad.

We have several thesis projects available:

  • Implementation of microwave excitation in a Millikelvin Scanning Tunneling Microscope for ultrafast measurements
    You will implement a new low-dissipation design idea for microwave transmission lines that can inject ultrafast signals into a state-of-the-art scanning tunneling microscope operating at 50 mK temperature. You will apply this setup to perform spectroscopy of molecular and atomic qubits with atomic spatial resolution. This thesis is part of the Loth group’s research in the Center for Applied Quantum Technology, ZAQuant.


  • Electron spin resonance spectroscopy of individual molecules
    In this cutting-edge project, we will use electron spin resonance spectroscopy (ESR) in a state-of-the-art scanning tunneling microscope (STM) to achieve quantum control of the spin of individual atoms and molecules. This new technique has recently achieved unprecedented combination of spatial, temporal and energy resolution. In this project you will extend this method to designer molecules that are candidates for molecular quantum processors. This thesis is part of the Loth group’s research in the Center for Applied Quantum Technology, ZAQuant.


  • Atomic scale generation of coherent acoustic phonons
    Recent experiments with our ultrafast scanning tunneling microscope showed that tip-enhanced Terahertz fields generate extremely localized femtosecond forces. These forces excite coherent acoustic phonons at the atomic scale enabling a new way to control matter dynamically. You will use this new method to measure coherent acoustic phonons in atomically designed nanostructures and two-dimensional materials and thereby gain understanding of localized phonon modes and electron-phonon interaction. This thesis is part of the Loth group’s ultrafast imaging laboratory at the FMQ.


  • Quantum stochastic resonance of atomically assembled quantum magnets
    Recently, the group has developed a new measurement technique that allows for the full characterization of multi-level quantum systems over a broad frequency range from kHz to more than 10 GHz, called quantum stochastic resonance. You will apply this novel technique to quantum magnets that you assemble by atom manipulation. On these nanostructures, you will investigate the fundamental quantum mechanical processes that cause decoherence and quantum tunneling of the magnetization. This thesis is part of the Loth group’s research in the Center for Applied Quantum Technology, ZAQuant.


  • Coupling a tunable laser for resonance excitation of single molecules
    You will develop and implement a new optics design that couples a highly tunable laser source to the tunnel junction of a scanning tunneling microscope. You will characterize this setup aiming at a measurement of atomically localized generation and dynamics of excitons and photoelectrons in molecules and 2D semiconductors. This project is part of the Loth group’s next-generation scanning probe microscope that will explore light-matter interaction with unprecedented precision at the atomic scale.
