DESCRIPTION:Prof. Dragan Mihailovic\, Jožef Stefan Institute\, Ljubljana 
 Slovenia\nNon-equilibrium states in condensed matter\, and particularly me
 tastable states discovered a decade ago (Science\, 344\,177 (2014)) have b
 ecome of great interest in recent years because of their wide fundamental 
 relevance in different areas of physics as well as possible new applicatio
 ns. Various time-resolved techniques in combination with non-equilibrium s
 canning tunnelling microscopy has enabled us to investigate mesoscopic spa
 tio-temporal dynamics of charge fractionalization\, electron jamming and t
 opologically arrested reveal the unusual charge ordering kinetics in the p
 rototypical transition metal chalcogenide 1T TaS2 in great detail\, reveal
 ing very interesting fundamental new physics.\nThe metal-insulator transit
 ion which accompanies the metastable state switching is shown to be useful
  for low-temperature memristor devices. Extensive characterisation of such
  devices shows that they stand apart by orders of magnitude in relation to
  other state of the art memory devices in terms of both speed and energy e
 fficiency. The prospects for the use of such devices in superconducting cr
 y-computing applications is demonstrated by functional hybrid devices.\n\n
 Bio: Dragan Mihailovic did his undergraduate degree in Physics and PhD at 
 Oxford\, UK. Currently he is head of Department of Complex Matter at the J
 ozef Stefan Institute and Director of CENN Nanocenter. His primary interes
 t is in fundamental problems in condensed matter physics\, both experiment
 al and theoretical\, and his work has been largely driven by curiosity. Hi
 s major achievements include: the first systematic measurements of ultrafa
 st time-resolved spectroscopy in cuprate superconductors\, the experimenta
 l discovery of polar metals\, the discovery of high-temperature fullerene 
 ferromagnets with record Curie temperature and the discovery of the mechan
 ism responsible for fullerene ferromagnetism. Together with Kabanov he pro
 posed a polaronic mechanism of Jahn-Teller pairing and percolative superco
 nductivity. He was the first to report a time-resolved study of fullerenes
 \, performed the first studies of CDW transitions in 1D and 2D\, the first
  observation of collective mode dynamics through a symmetry breaking trans
 ition. He proposed experiments\, and (co)discovered a polaronic quantum sp
 in liquid\, performed the first demonstration of Grover’s algorithm with
  collective CDW excitations and reported the discovery of a hidden quantum
  state in a transition metal dichalcogenide\, which he is now investigatin
 g as promising cryocomputing memory devices. His team reported the first n
 onequilibrium topological transition\, and most recently the discovery of 
 quantum jamming and recently\, simulations of domain melting on a quantum 
 computer.
