The Department of Physics at Chalmers invites applications for a PhD position targeting inverse design of nanomechanical resonators. This position is part of a larger 5-year project funded by the K&A Wallenberg Foundation aimed at realizing optomechanical systems reaching deep into the quantum regime. You will thus be part of a newly formed team of six PhD students and postdocs in different local theoretical and experimental groups working towards a common goal. For this PhD project, we seek a highly motivated candidate with an interest in computational electromagnetism, mechanics, and/or machine learning. We are looking for someone who wishes to do theoretical work, while still maintaining close contact with experiments.

Project description

Optomechanics is a vibrant research field spanning multiple disciplines within physics. Reaching the deep quantum regime imposes strict requirements on the mechanical and optical performance of mechanical resonators. These micrometer-sized devices are now routinely fabricated in the Chalmers cleanroom, but the challenge remains to achieve resonator designs with ultralow loss while retaining strong optomechanical coupling and good mechanical properties.

In this PhD project, the focus will be on implementing inverse design methods for designing and optimizing the optical and optomechanical performance while maintaining favourable mechanical properties. The initial stage of this project is focused on the design of nano-optic resonators. The research will be carried out in close proximity to researchers working on inverse design of nanomechanical devices. The second stage of the project aims to integrate the two approaches into a single framework.

As a PhD student you will be embedded in the joint project and your designs will be fabricated and tested by experimental groups at Chalmers. You will be part of the CMMT division, a research group tackling questions ranging from nanomechanics to optics and quantum physics. Chalmers is a leading research institution in nanoscience and hosts one of Europe’s largest clean rooms, as well as state-of-the-art high-performance computing equipment.

Major responsibilities

Your major responsibility as a PhD student is to pursue your doctoral studies. This includes developing scientific concepts and communicating research results both verbally and in writing. In addition, you will also take graduate courses. The majority of your working time will be devoted to your own research and competence development, but the position generally also includes teaching or other departmental duties. A PhD position at Chalmers is a full-time, time-limited position and an opportunity to qualify for further research positions within academia or industry. We offer a competitive salary, excellent working conditions, and access to world-class infrastructure.

Qualifications

* You should have, or expect to soon obtain, a M.Sc. degree (or equivalent corresponding to at least 240 ECTS) in physics, optics, nanoscience, electrical engineering, or a related subject area.
* You will be expected to take initiative, work independently when needed, demonstrate creativity, and take responsibility for your work.
* You need to be able to disseminate results and knowledge within the scientific community and to a broader public. To that end, you should have good command of both spoken and written English.

Courses in solid mechanics, computational physics and programming, machine learning, optics, and electrodynamics are meritorious.
