Dear colleagues,

You are cordially invited to the IPB COLLOQUIUM which will be held on Monday, 21 May 2018 at 12:00 in the “Zvonko Marić” lecture hall of the Institute of Physics Belgrade. The talk entitled

Engineering Weyl semimetals and anyons

will be given by Prof. Dr. Hrvoje Buljan (Department of Physics, Faculty of Science, University of Zagreb, Croatia). Abstract of the talk:

In this talk we will present two topics of research in our group related to synthetic topological quantum matter [1]: topological phases in 3D optical lattices, more specifically a proposal for experimental realization of Weyl semimetals in ultracold atomic gases [2], and anyons [3,4]. We will present one possible route to engineer anyons in a 2D electron gas in a strong magnetic field sandwiched between materials with high magnetic permeability, which induce electron-electron vector interactions to engineer charged flux-tube composites [3]. We will also discuss intriguing concepts related to extracting observables from anyonic wavefunctions [4]: one can show that the momentum distribution is not a proper observable for a system of anyons [4], even though this observable was crucial for the experimental demonstration of Bose-Einsten condensation or ultracold fermions in time of flight measurements. We will show how time-of-flight measurements can be used to extract anyonic statistics [4].
