Chalmers University of Technology Doctoral Scholarship in Sweden

There’s a genuinely elegant physics problem sitting at the heart of this PhD position: when an electron moves through a material, it doesn’t travel alone — it drags the surrounding atomic lattice along with it, forming what physicists call a polaron. Understanding exactly how that interaction behaves determines whether a solar cell material is efficient or wasteful, and this fully funded doctoral position at Chalmers University of Technology exists specifically to model that behaviour using some of the most advanced computational physics tools available.

Applications closed on 31 March 2026, so this specific opening is no longer accepting candidates. This guide explains what the research involves, outlines the academic background that strengthens an application, details the full Swedish employment package offered with the position, and highlights where to find similar opportunities if another candidate has already filled this project.

What This PhD Position Involves

Based within the Division of Condensed Matter and Materials Theory at Chalmers’ Department of Physics, this position sits inside a research group focused on constructing theoretical models of materials and condensed matter systems, sometimes leading directly to new materials and technologies. The project centres on polarons — quasiparticles formed when electric charges interact with a material’s atomic lattice — and specifically how these interactions influence the efficiency of solar-energy materials.

The successful candidate develops theoretical frameworks and computational tools to describe these charge-lattice interactions, analyses their impact on material properties, and works toward identifying design principles for genuinely improved solar absorbers, with direct application to next-generation semiconductors for solar cells and solar-to-fuel conversion technology.

Chalmers University of Technology Doctoral Scholarship Summary

What Makes You Eligible for This Position

• You need a Master’s degree (120 credits) or a Magister degree (60 credits) in Physics, Chemistry, or Materials Science
• If your education was completed outside Sweden, a 4-year Bachelor’s degree is accepted in place of a formal Master’s
• You need strong written and spoken English communication skills
• You need genuine ability to work both independently and collaboratively, since the role spans solo theoretical development and active collaboration with experimental partners

What Strengthens an Application Beyond the Baseline Requirements

• Prior experience in computational modelling and electronic-structure methods
• Programming experience, particularly relevant to scientific computing
• Machine learning experience, since the project explicitly uses ML methods alongside traditional electronic-structure calculations and molecular dynamics

Given how technically specific this project is, candidates who can point to genuine hands-on experience with any of these three areas — even at a project or thesis level rather than professional research — stand out meaningfully against applicants with strong grades but no direct computational background.

What the Role Actually Involves Day to Day

• Using advanced electronic-structure calculations, machine learning methods, and molecular dynamics to model polaron behaviour in candidate solar-energy materials
• Developing theoretical frameworks and computational tools specifically describing charge-lattice interactions
• Taking advanced-level courses through the Graduate School of Physics or Materials Science
• Developing your own independent research ideas within the broader project scope
• Collaborating directly with experimental research partners, connecting theoretical modelling to real material testing
• Publishing research findings in scientific journals and presenting results at international conferences
• If you opt into the teaching component (up to 20% of your working time), delivering undergraduate-level teaching or equivalent duties, which extends your position from four to five years

What This Position Actually Pays

• A starting monthly salary of 34,550 SEK (figure valid from 25 May 2025 — worth checking for any subsequent adjustment when applying to future similar openings)
• Chalmers employs you under a formal employment contract rather than awarding a traditional stipend or scholarship. From your first day, you become a salaried staff member and receive the full range of associated employee benefits.
• Access to Swedish language courses, if Swedish isn’t your native language
• A fully funded position throughout, with no tuition fees or additional costs to the doctoral student
• The opportunity to live and work in Gothenburg, Sweden’s second-largest city and a genuine international research hub

Doctoral studies under this position require your physical presence in Sweden throughout the full study period — this isn’t a remote or hybrid arrangement.

Required Documents

• A current CV
• Your Bachelor’s thesis, together with your academic transcript
• Your Master’s thesis and transcript, if available at the time of application

You must submit every required document in English as an individual PDF file with a maximum size of 40 MB. The application system does not accept ZIP files, so you cannot combine multiple documents into a single compressed folder.

What the Application Process Required

1. Prepare every application document in English
2. Convert all required documents into individual PDF files, keeping each under the 40MB size limit
3. Access the official application form through the button at the foot of Chalmers’ official job listing page
4. Upload every required document
5. Submit the complete application before the deadline
6. Applicants were responsible for ensuring their own application was genuinely complete — incomplete applications, and applications sent by email instead of through the official system, were not considered
7. Contact details for references were only requested after the interview stage, not upfront as part of the initial application

What the Deadline and Selection Timeline Look Like

• Application deadline: 31 March 2026 — now closed
• Selection process: Reviewed directly by the supervising Associate Professor and the department, with references only contacted after an initial interview stage
• Because this is a single, specific funded position rather than an annual institutional scholarship, there’s no fixed “next cycle” tied to this exact project

What to Do If You’re Interested in Similar Positions

• Chalmers posts new PhD positions continuously across its departments, with dozens of openings active at any given time spanning physics, materials science, AI, and engineering — check Chalmers’ official vacancies page directly and regularly, rather than waiting for this specific project to reopen
• Follow the Division of Condensed Matter and Materials Theory specifically, since new funded projects in this research area are likely to be announced there as new grants and collaborations begin
• Build demonstrable experience in electronic-structure methods, computational modelling, or machine learning now if you’re aiming for a similar position, since this was explicitly called out as strengthening an application
• If you’re specifically interested in Julia Wiktor’s research group, consider reaching out directly to express interest in future opportunities, even outside an active posting
• Set up a job alert on Chalmers’ careers platform for physics and materials science PhD openings, since positions in this space are posted on a rolling basis throughout the year rather than through one annual cycle

Frequently Asked Questions

Is this specific PhD position still accepting applications?

No. The deadline was 31 March 2026, and this specific opening is no longer accepting candidates.

Is this a scholarship or an actual job?

It’s a genuine employment contract with Chalmers University, not a stipend-based scholarship. You receive a salary and full Swedish employee benefits from the start.

Do I need prior machine learning experience to apply for positions like this?

Not strictly required, but genuine programming and machine learning experience was explicitly noted as strengthening an application for this specific project.

Can I complete this PhD remotely from outside Sweden?

No. Physical presence in Sweden throughout the full study period is required.

How can I find similar future openings at Chalmers?

Check Chalmers’ official vacancies page directly and regularly, since the university posts new PhD positions across departments on a rolling basis throughout the year, rather than through one fixed annual scholarship cycle.
