Weyl points as synthetic magnetic monopoles in ultracold atomic gases
In relativistic quantum field theory there are three types of fermions: Dirac, Majorana, and Weyl fermions, but the latter two have never been observed in particle physics. Scientists have attempted to realize Weyl fermions in other systems, but they eluded experimental observation from 1929 until 2015. In a recent paper in Physical Review Letters, Tena Dubček and Hrvoje Buljan from the Faculty of Science University of Zagreb, in Collaboration with two groups from MIT, that of Marin Soljačić and Nobel Laureate Wolfgang Ketterle, have proposed a viable path towards realization of Weyl fermions in ultracold atomic gases.

Experimental demonstration of the synthetic Lorentz force
In a recent paper published in Scientific Reports ( http://www.nature.com/articles/srep13485 ), Neven Šantić, Tena Dubček, Damir Aumiler, Hrvoje Buljan and Ticijana Ban experimentally prepared conditions using cold atoms and lasers where atoms, which are neutral particles, will behave like charges in magnetic fields. Charged particles in magnetic fields experience the Lorentz force which bends their trajectory, because the force is orthogonal to their velocity. In a recent experiment, researchers from Zagreb have created synthetic Lorentz force acting on neutral atomic particles. The research is on interest for creating table-top emulators of complex interacting systems. The experiment was led by Ticijana Ban from the Institute of Physics, and the theory was led by Hrvoje Buljan from the Department of Physics, Faculty of Science, University of Zagreb (UniZG).
