The Windchime collaboration is implementing the idea to detect the passage of Dark Matter through its gravitational interaction alone,using an array of accelerometers as sketched out in arXiv:1903.00492. Initial work includes the simulation of such an experiment and the characterization of its sensitivity as function of the various experimental parameters, and data taking with an initial prototype experiment using commercial accelerometers. The design and commissioning of a first setup with custom-made accelerometers and a readout that incorporates strategies to improve the signal/noise such as squeezed light and quantum back-action evasion will result in new information on the allowed Dark Matter parameter space. An analysis problem to be solved is finding faint tracks in time-series data from an array of sensors, where a milestone would be determining how to optimally analyze such data.

Two positions are available to start immediately, one hosted by Rice University, the other by Purdue University. Remote work can be arranged. The positions will remain open until filled and applications received before January 20, 2021 will receive full consideration. The appointees are expected to collaborate closely with each other and the entire Windchime collaboration, which also involves scientists from the Oak Ridge, Berkeley, and Fermi National Laboratories, as well as from NIST and the University of Maryland. Applicants should enjoy working as part of a team with researchers at all levels and from various backgrounds.

A PhD in physics or a related field, including computer science or electrical and computer engineering, is required. Experience with experimental particle physics, dark matter detection, AMO techniques such as squeezed light and quantum back-action evading methods, or the analysis of time series data will be advantageous.

We strongly value different backgrounds and experiences and are looking for candidates that reflect the diversity of the graduate student and postdoctoral population. Applicants from underrepresented groups are especially encouraged to apply.

Questions regarding this position should be directed to Prof. Rafael Lang at and Prof Christopher Tunnell at . Applicants should provide a statement of prior expertise, their research interest in this effort, a curriculum vitae with a list of publications, and arrange for at least two letters of reference to be sent directly.
