at the Department of Physics. Closing date: 2 March 2018.

The Department of Physics is located in the AlbaNova University Center and has approximately 240 employees, 250 students at undergraduate level and 90 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.

An important task in condensed matter physics is to classify what types of phases of matter can exist in nature and to determine their properties. With the discovery of the quantum Hall effect, it became apparent that specifying the symmetries of a phase is not sufficient to comprehensively describe its properties. Instead, concepts from topology and quantum information have proven to be necessary to classify such ‘topological phases of matter’. Of particular interest are interacting topological phases, usually referred to as ‘topologically ordered’, because their excitations have very unusual properties, e.g. they carry fractional quantum numbers. Determining those properties --- or even whether a phase is topologically ordered at all --- is often very difficult. One of our most promising tools for this task is to analyze the entanglement features of the ground state, such as the so-called entanglement spectrum. 

There is an open PhD position with start date in fall 2018 in the group of Maria Hermanns. The successful candidate is expected to study the effect of symmetries on topologically ordered systems. These may enrich the topologically ordered phase, thus leading to a larger variety of phases. The student will both classify what types of phases may be possible and what the corresponding properties and experimental signatures are. A second aim of the project is to develop a deeper understanding of the entanglement spectrum as a tool to classify topological phases of matter. In particular, the student will explore how topological properties and invariants are linked to various features in the entanglement spectrum.

Education at the research level
A PhD education at Stockholm University is four years (48 months). The 4-year PhD program includes at least 3 years of research and at most one year of course work. The position may be extended by up to one year if up to 20 % teaching assistance or administration is included in the contract. The PhD student is employed (“doktorandanställning”) during the studies, with a monthly salary starting at SEK 25 300.

Qualification requirements
In order to meet the general entry requirements, the applicant must have completed a second-cycle degree, 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.

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 qualification requirements must be met by the deadline for applications.

Selection
The selection among the eligible candidates will be based on their capacity to benefit from the training. The successful applicant will be selected based on documented theoretical and experimental knowledge relevant for the area of study, knowledge of scientific theory and method, analytical skills, personal motivation and team working skills. Well-developed English language skills are required. The applicants are encouraged to provide supporting documents that substantiate qualifications, e.g., knowledge, skills, abilities and experience. References and interviews will be used to assess qualifications of the applicants. We seek a self-motivated candidate with good analytical abilities and skilled in English.

Admission Regulations for Doctoral Studies at Stockholm University are available at: www.su.se/rules.

Terms of employment
Only a person who will be or has already been admitted to a third-cycle programme may be appointed to a doctoral studentship.

The term of the initial contract may not exceed one year. The employment may be extended for a maximum of two years at a time. However, the total period of employment may not exceed the equivalent of four years of full-time study.

Doctoral students should primarily devote themselves to their own education, but may engage in teaching, research, and administration corresponding to a maximum of 20 % of a full-time position.

Please note that admission decisions cannot be appealed.

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