Theme 1. Dark matter direct-detection experiments with the sensor network made of optical atomic clocks

Theme 1 will be divided in to two work packages:

  • Task 1.1: Development of a world-wide dispersed network of existing optical clocks (Months 1-12)
  • Task 1.2: The dark matter observation sessions (Months 6-36)


In the first research task of this theme we will establish a structure of a geographically dispersed network of existing optical clocks. We will provide new methods of clock synchronisation. Moreover, we will develop algorithms and computer codes for data analysis and their physical interpretation. We will supply a direct recipe for connecting other already operating clock into our global network of sensors.

In the second task of this theme we will test the performance of the worldwide quantum sensor network and coordinate the observation sessions based on the core network made of the optical atomic clocks located in our laboratory and in our partners’ laboratories. The primary goal of these sessions is the positive detection of non-baryonic dark matter in the form of topological defects and oscillating scalar fields.  The accuracy and stability of the contributing optical clocks as well as the design of the proposed network will provide access to vast regions of the parameter space inaccessible for all the previous approaches. The proposed quantum sensors network will give us a real chance for the first laboratory positive detection of the dark matter.
