PhD student in Physics: open quantum system simulations with trapped ions

The Department of Physics is located in the AlbaNova University Center and has approximately 240 employees, 250 students at undergraduate level and 70 graduate students. There are four research subjects within the postgraduate program: Physics, Theoretical Physics, Chemical Physics and Medical Radiation Physics. These subjects span over several research groups with different research activities. For information about the Department of Physics, see: www.fysik.su.se/english.

Project description

Subject: Physics

The Trapped Ion Quantum Technology Group at Stockholm University invites applications for a highly motivated PhD student to join our experimental trapped ion research. The aim of the PhD project is to investigate open spin-boson systems with trapped ions. This position is part of the QuantERA project " Collective quantum phenomena in dissipative systems – towards time-crystal applications in sensing and metrology (CoQuaDis)".

The CoQuaDis project aims to study many-body phases in open quantum systems and to demonstrate their use in sensing and timekeeping. At Stockholm University, we realize such systems using crystals of trapped ions, which provide long trapping times, controllable interactions mediated by collective vibrations, and in-situ cooling. This enables stable operation and continuous readout of dissipative many-body phases. This highly controllable platform allows us to address fundamental questions in open quantum many-body dynamics.

The PhD project is experimental and will be carried out within the Trapped Ion Quantum Technology Group at Stockholm University. It will involve close collaboration with theoreticians at the University of Tübingen, Germany and the IFISC, Mallorca, Spain.

We are looking for a highly motivated candidate with a strong interest to work on trapped ion quantum experiments. For more information about our group and current projects, please visit https://qtech.fysik.su.se/.

This project is funded within the QuantERA II Programme that has received funding from the EU H2020 research and innovation programme under GA No 101017733.

Qualification requirements

In order to be admitted to postgraduate education, the applicant must have the general and specific entry requirements. The qualification requirements must be met by the deadline for applications.

You meet general entry requirements if you have completed a second-cycle degree, or completed courses equivalent to at least 240 higher education credits, of which 60 credits must be in the second cycle, or have otherwise acquired equivalent knowledge in Sweden or elsewhere.

Specific entry requircements. In order to be accepted as a PhD student in Physics or Theoretical Physics a BSc in Physics (or equivalent) is required. The studies must include 60 credits of second-cycle courses in physics out of which at least 15 credits correspond to a second-cycle degree project. The degree project does not have to have been examined at the application deadline, but work corresponding to half a semester of full-time studies should have been devoted to it. For the subject Chemical Physics courses in chemistry may replace the required physics courses. The subject Medical Radiation Physics requires a second-cycle degree project of 30 credits in the subject area, or with 60 credits of physics, a second-cycle degree project of 30 credits in another subject area.

In addition, proficiency in English language, equivalent to English B in Swedish high school, is required, or

• Previously completed University degree taught in English
• IELTS score (Academic) of 6.0 or more (with none of the sections scoring less than 5.0)
• TOEFL score of 550 or more (computer based test 213, internet based 79)
• Cambridge/Oxford - Advanced or Proficiency level

Selection

The selection among the eligible candidates will be based on their capacity to benefit from the training. The following criteria will be used to assess this capacity:

• documented knowledge in a relevant field of research
• capacity for analytical and creative thinking
• initiative
• independence
• ability to collaborate
• written and oral proficiency.

About the employment

We offer a fixed-term employment as a doctoral student according to Chapter 5 of the Higher Education Ordinance (1993:100). The period of employment may not be longer than what corresponds to full-time doctoral education for four years. As a doctoral student, you should primarily devote yourself to your own doctoral education, but the employment may include work with education, research and administration to a limited extent (maximum 20 %).

A new employment as a doctoral student is for a maximum of one year, the employment is then renewed for a maximum of two years at a time.

Stockholm University strives to be a workplace free from discrimination and with equal opportunities for all.
