The position is part of the project Accurate Modeling of Dark Matter – Electron Interactions in Liquid Xenon and Argon, a Swiss National Science Foundation collaborative project with the group of Riccardo Catena at Chalmers University.

The overall goal of the project is to develop, numerically implement, and apply a theoretical framework to accurately describe the expected dark matter-induced electron ionization events in operating liquid xenon and argon detectors.

The postdoctoral researcher will focus on:

• Developing and implementing a state-of-the-art treatment of the xenon and argon liquid phase using electronic structure calculations.
• Developing computer code for computing ionization rates with general dark matter-electron interactions.
• Exploring appropriate descriptions of electron final states.
• Calculating dark-matter-induced ionization rates for liquid xenon and argon, with full treatment of final states, in-medium screening, and general dark matter-electron interaction types.

A PhD in Computational Materials Physics or a related area is required.

• Experience with electronic structure calculations, including writing computer code, is essential.
• Familiarity with or interest in field theory and astroparticle physics is desirable.

Candidates should be able to work both independently and collaboratively and contribute to the positive research group environment. The research team functions most effectively when the members have a diversity of backgrounds, and we aim to be 100% LGBTQ+ friendly.

• Your career with impact: Become part of ETH Zurich, which not only supports your professional development, but also actively contributes to positive change in society.
• We are actively committed to a sustainable and climate-neutral university.
• You can expect numerous benefits, such as public transport season tickets and car sharing, a wide range of sports offered by the ASVZ, childcare and attractive pension benefits.

In line with our values, ETH Zurich encourages an inclusive culture. We promote equality of opportunity, value diversity and nurture a working and learning environment in which the rights and dignity of all our staff and students are respected.

We look forward to receiving your online application with the following documents:

• A one-page letter of interest explaining your motivation for working on the project, how your background prepares you for it, and how it will help you achieve your career goals.
• Your CV
• Your publication list
• The names and email addresses of two references

The start date is flexible, with a preference for before the end of Summer 2025. The position will remain open until filled, but please apply before mid-March to ensure full consideration.

Please note that we exclusively accept applications submitted through our online application portal. Applications via email or postal services will not be considered.
