Boris Tzukerblat, a distinguished scientist in the field of quantum physics, has dedicated his research to exploring the potential of molecular quantum cellular automata (QCA) for revolutionizing nano-electronics and computing. In 2023, his work delved into developing a vibronic theory of clocking in molecular QCA, focusing on a trimeric mixed-valence (MV) system. This research provided insights into the electron transfer mechanism, vibronic coupling, and the role of electric fields in encoding binary information and performing clocking operations within the molecular system.Additionally, Tzukerblat investigated the effects of electronic and vibronic interactions on heat release during nonadiabatic switching of electric fields in mixed-valence dimers. Through quantum mechanical vibronic modeling, he identified optimal parametric regimes for minimizing heat release while maintaining a strong nonlinear response—a crucial consideration for molecular switchable devices.Furthermore, Tzukerblat's research extended to the optical properties of rare-earth ions in doped crystals, such as terbium and europium in yttrium tantalate phosphors. Employing group-theoretical arguments, he elucidated selection rules for optical transitions and polarization rules for vibronic satellites. These findings contribute to the development of optoelectronic devices by providing a deeper understanding of luminescence properties and the identification of spectral lines.In recognition of his expertise, Tzukerblat served as a member of the International Organizing Committee for the 25th International Symposium on the JahnTeller Effect in May 2023, demonstrating his leadership and influence in the scientific community. Through his innovative research and contributions, Boris Tzukerblat continues to advance the frontier of quantum physics, paving the way for future breakthroughs in molecular electronics and optoelectronics.
