3 PhD positions in experimental AMO physics: quantum-engineered precision measurements of single ions
3 PhD positions are available within a recently founded research consortium involving VU Amsterdam and University of Amsterdam. The consortium will develop the next generation of experiments for precision measurements of simple atomic and molecular ions for tests of quantum electrodynamics and searches for new physics beyond the standard model.
Are you enthusiastic to search for new physics beyond the Standard Model with highly advanced methods and equipment? Do you get excited about developing quantum detection methods, and all the high-tech that is required for it, to help unravel the mysteries in our understanding of the universe? Then please apply for this PhD position at Vrije Universiteit Amsterdam.
FTE: 1 - 1
Position 1 - Quantum-engineered precision measurements of a single H2+ molecular ion
Help us in implementing techniques from the quantum computing toolbox to reach unprecedented accuracies in the spectroscopy of the simplest molecule in our universe - H2+. You will work as a PhD student in a team on the project that aims to do the first precision measurement of transitions between weakly-bound states of trapped H2+ for new tests of quantum-electrodynamics and fundamental constants. It will be your task to develop quantum-logic state detection schemes for H2+ with a co-trapped Be+ ion, and use this to strongly advance the potential of H2+ spectroscopy. The work involves many aspects, like working with, and development of, advanced lasers, nonlinear optics, ion trapping, quantum state manipulation, radio-frequency and microwaves, ultra-high vacuum, high-harmonic generation, simulations, and more.
- developing and implementing a new ion trap apparatus that employs a quantum-logic scheme to manipulate and detect the state of H2+ ions using the Zeeman effect
- putting textbook quantum mechanics, optics and electronics into practice by
designing, simulating, conducting, and analyzing measurements of H2+ molecular ions
- make the most accurate measurements of weakly-bound states of H2+ and measure the splitting between the two nuclear spin states (ortho and para)
- spend at most 10% of your time on teaching duties
Position 2 - Quantum-engineered precision measurements of a single HD+ molecular ion
As a PhD student, you will develop, construct, commission and operate the world's most precise apparatus for quantum-engineered measurements a single trapped HD+ molecular ion.
- design, construction, and commissioning of an ion trap vacuum apparatus for storing a single Be+ qubit ion together with a single HD+ molecular ion
- phase-stabilization of lasers for HD+ excitation to a reference laser with 1 Hz line width
- development of coherent control techniques for deterministic preparation of the vibrational, rotational and spin quantum state of the HD+ molecule
- carry out the world's most precise measurements of rotational and vibrational transition frequencies of HD+ for tests of fundamental physical law and searches for 'new physics'
- spend at most 10% of your time on teaching duties
Position 3 - Quantum-engineered precision measurement of the 1S-2S transition in He+ for fundamental tests
You will work as a PhD student in a team on the project that aims to do the first precision measurement of the 1S-2S transition in a single trapped He+ for new tests of quantum-electrodynamics and fundamental constants. It will be your task to develop quantum-logic state detection schemes for He+ with a co-trapped Be+ ion, and use this to strongly advance the potential of He+ spectroscopy. The work involves many aspects, like working with, and development of, advanced lasers, nonlinear optics, ion trapping, quantum state manipulation, ultra-high vacuum, high-harmonic generation, simulations, and more.
- develop quantum-logic detection of the 1S-2S transition in a single trapped He+ ion
- test new ideas for fast He-ion loading and laser cooling to the motional ground state
- work in a team to do the first precision measurements of the 1S-2S transition frequency in He+, and based on this perform an unprecedented test of QED and fundamental constants to search for 'new' physics
- spend at most 10% of you time on teaching duties
- a MSc degree in Physics, Physical Chemistry or Applied Physics, preferably specializing in atomic, molecular, and/or optical physics
- you have great enthusiasm for working at the forefront of science and technology
- a creative mind and independent 'self-starting' attitude, with the ability to see
beyond boundaries, set priorities, and develop your skills through self-study where needed
- demonstrated hands-on experience in optics, electronics, lasers, vacuum
systems, and system automation is nice, but not a requirement
