Deadline : Open until filled
(04) PhD Degree – Fully Funded
PhD position summary/title: PhD Student in Thin Film Condensed Matter Physics
- Develop of a thin-film preparation chamber
- Study thin-film, hybrid interfaces of quantum materials
- Perform low-energy muon-spin spectroscopy (LE-μSR) and beta-detected NMR (β-NMR) on thin films
- Contribute to ongoing activities of the LEM group at PSI and the β-NMR group at CERN
- Participate in teaching and graduate school activities at the University of Zurich
Deadline : Open until filled
(05) PhD Degree – Fully Funded
PhD position summary/title: PhD Student in experimental physics
In close collaboration with experts at PSI and the University of Zürich, the PhD candidate will contribute to significantly expanding the high-pressure capabilities of μSR at PSI. This effort will involve enabling measurements on substantially smaller quantum materials at much higher pressures through the use of diamond anvil cells and advanced uniaxial stress techniques. The doctoral researcher will participate in the development of new hydrostatic and uniaxial pressure cells, as well as associated experimental methodologies, with the aim of extending the accessible pressure range by at least a factor of three beyond the current records achieved at the Paul Scherrer Institute PSI. These advances will open access to previously unexplored regimes of quantum matter and allow the study of emergent phenomena under extreme conditions.

(07) PhD Degree – Fully Funded
PhD position summary/title: PhD Student for MiningBrines DC13: Modelling the evolution of geothermal waters during multi-resource extraction
The project “Modeling workflow development and application for fluid chemistry evolution from extraction to re-injection.” aims to advance the understanding and prediction of fluid behavior in complex geo energy systems from extraction to re-injection. A central objective is to quantify how geological, geochemical, and engineering factors jointly influence fluid composition and, ultimately, the efficiency of geothermal energy production together with extraction of critical minerals.
Deadline : Open until filled
(08) PhD Degree – Fully Funded
PhD position summary/title: PhD Student for MiningBrines DC16: Pore-scale reactive transport modelling for utilization of geothermal reservoirs
The project “Reactive transport modeling (Hydraulic Chemical) at the pore scale and upscaling to reservoir scale” develops advanced pore scale reactive transport modeling capabilities by extending an in house lattice Boltzmann based transport solver to explicitly resolve microstructural evolution in reservoir rocks driven by mineral dissolution and precipitation. These simulations quantify how coupled flow, transport and chemistry processes cause dynamic changes in pore geometry, in transport properties, and reactive surface area under geothermal conditions.

About The Paul Scherrer Institute (PSI), Switzerland- Official Website
The Paul Scherrer Institute (PSI) is a multi-disciplinary research institute for natural and engineering sciences in Switzerland. It is located in the Canton of Aargau in the municipalities Villigen and Würenlingen on either side of the River Aare, and covers an area over 35 hectares in size. Like ETH Zurich and EPFL, PSI belongs to the ETH Domain of the Swiss Confederation. The PSI employs around 3000 people. It conducts basic and applied research in the fields of matter and materials, human health, and energy and the environment. About 37% of PSI’s research activities focus on material sciences, 24% on life sciences, 19% on general energy, 11% on nuclear energy and safety, and 9% on particle physics.
PSI develops, builds and operates large and complex research facilities and makes them available to the national and international scientific communities. In 2017, for example, more than 2,500 researchers from 60 different countries came to PSI to take advantage of the concentration of large-scale research facilities in the same location, which is unique worldwide. About 1,900 experiments are conducted each year at the approximately 40 measuring stations in these facilities.
