PhD Position Delocalized Quantum Magnetism in Atomic Spin Assemblies

We currently have an opening for a PhD student in our group. See the description below for a general overview. More detailed information can be found here.

Research description

The PhD project is part of a larger research effort in the field of atomic-scale spin dynamics. In our group we use scanning tunneling microscopy (STM) to study individual magnetic atoms. In addition to visualising the atoms, the tip of the STM can be used to position the atoms one-by-one into an arrangement of choice. We use this methodology to assemble custom-engineered spin structures, thus creating real-world examples of textbook spin Hamiltonians.

Specifically, the aim of this PhD project is to investigate assemblies where neighbouring atoms are sufficiently close for their outermost valence electrons to form molecular orbitals. As such, the s-shell magnetism will become delocalized across larger length scales, providing pathways for interacting with localized f-shell and nuclear spins over extended distances. The project offers ample freedom for customization and differentiation depending on your personal research interests.

You will use a variety of measurement techniques, including inelastic electron tunneling spectroscopy (IETS) and electron spin resonance (ESR), implemented within the STM, to address the atomic spin states. Making use of advanced nanosecond pulsed measurement techniques, you will study the coherent quantum dynamics of the electron, orbital and nuclear magnetic moments of various isotopes. The research builds further on recent achievements in our group, including single-shot nuclear readout and electron-nuclear double resonance (ENDOR).

Job Requirements

  • MSc degree in Physics or a closely related discipline.
  • Solid understanding of quantum mechanics, in particular spin physics. Even more important than that: an intrinsic motivation to expand your knowledge of these topics.
  • Experience with experimental research, preferably including vacuum and cryogenic techniques. Specific knowledge of STM is not required.
  • Experience with coding, preferably in Python.
  • Team-working mentality as well as the ability to operate efficiently on your own.
  • Excellent control of the English language, in both spoken and written form.
