Experimental set-up for ultracold chemical reactions

We will develop experimental platforms for tuning ultracold chemical reactions. These platforms can, e.g., include the possibility for the reactants to be photoassociated with a laser, to optically couple the reactants to Rydberg states, to magnetically couple the reactants to Feshbach resonances, or to carry out reaction experiments in an optical cavity.

Theoretical models on coherent control of cold atoms and ultracold chemical reactions

The model will properly describe the possible processes taking place into theexperiment with cold atoms, in particular the control of the scattering process by scanning an appropriate external magnetic field. It will provide statistical description of scanning over many avoided crossings (in the adiabatic molecular levels) and to an optimisation procedure for designing ramping schemes for the magnetic fields/microwave dressing for creating cold molecules. The model will generate series of numerical simulations for accelerating resonant scattering of single atoms in order to assist in the analysis of accelerating resonant scattering of single atoms into specific entangled target states.We will set up and use models to investigate chemical reactions of atoms and (possibly) molecules in the ultracold regime. With these, we will identify schemes to control collisional processes and reactions. Possible elements of control can involve optical light fields, magnetic fields and Feshbach resonances, as well as Rydberg states, and placing the reaction in an optical cavity.

Communication, Dissemination and Exploitation Plan

The Report will contain our Plan for the Communication Activities (Web site for the General Public, Social Media), Dissemination Activities (Publication of Articles on Refereed Journals in Instrumentation and Physics, Participation of Researchers in International Conferences and Workshop), and Exploitation Plan.-The LU team members will participate in “Scientist Night” event organised every year by the university with visitors from different school age groups, students and general public. The group will prepare a short video for high school students in order to introduce its research topics of the project in a digestible way, adjusted to the level of understanding of the visitors. The rest of the consortium partners will be encouraged to organize/ participate in similar events on popularizing quantum physics.-The project coordinator will develop and keep regularly updated the project web site. It will contain general information on Q-DYNAMO, training events, fellows, project and research results (e.g., papers in scientific journals), as well as pages aiming at the general public. Special target group will be secondary school students, for whom the ESRs of the project will produce videoclips to highlight specific research topics. A leaflet, a poster and a short presentation on the network will be prepared as well as a form of outreach activities.-We will attract the attention of local media in order to cover the research activities of the project via articles in the press, social media ( Youtube, Facebook, Linkedin, Twitter), or short TV programmes and interviews. The project coordinator has previous experience engaging with the media, which will be used to deliver the scientific results to the public in a popular form.-We will organize two workshops within the current project, hosted by Latvia ( 2st year) and Italy ( 4th year). The workshops are intended to present current scientific achievements of the project, to plan future actions and maximize the scientific outputs, as well as to develop new strategies to achieve the project objectives. The workshops will extensively involve ESRs in order to train them in presenting progress reports and taking part in scientific discussions and planning. Via communication with their colleagues the ESRs will establish new contacts with scientists from other countries in order to build their own scientific network. We expect all team members involved in the project to participate in the workshops.-All team members will participate in relevant conferences and give seminars in Europe, USA, Japan and New Zealand to report the results from the project.Typical examples in USA are the GRC-Gordon Research Conferences and CLEO/QELS-laser science to photonic applications, while in Europe-CLEO/EUROPE and CEWQO-Central European Workshop on Quantum Optics, European Group on Atomic Systems (EGAS), European Conference on Atoms Molecules and Photons (ECAMP), International Conference on Photonic, Electronic, and Atomic Collisions (ICPEAC) and International Conference on Laser Spectroscopy (ICOLS))

Theoretical model on Rydberg-EIT with rf/mw

We will develop the theoretical basis for EIT in Rydberg atoms, where an external radio frequency (rf) or microwave radiation (mw) is used. The model will provide proper theoretical and numerical description of the involved processes and will serve as guidance for the planned experimental measurements.
