Two posters were presented by our group at 2017 European Frequency and Time Forum & International Frequency Control Symposium, Besançon, France: “Optical atomic clock as a detector of transient variation in fundamental constants” by Marcin Bober”  and “Towards blackbody radiation shift uncertainty in optical lattice clocks at 10^-18 level at room temperatures” by Piotr Ablewski. Moreover, Michał Zawada had a talk “Experimental constraint on dark matter-Standard Model coupling with optical atomic clocks”
