Abstract: Atomically engineered artificial lattices are a useful tool for simulating complex quantum phenomena, but have so far been limited to the study of Hamiltonians where electron–electron interactions do not play a role. However, it is… read more here.

Abstract: Aggregation-induced quenching (AIQ) of emission is an obstacle for the development of carbon dots (CDots) for solid-state luminescent devices. In this work, we introduce a method to avoid AIQ and to produce highly luminescent CDots… read more here.

DOI: 10.1103/physrevd.97.092008
Abstract: The experimental setup and results of the first search for invisible decays of orthopositronium (o-Ps) confined in a vacuum cavity are reported. No evidence of invisible decays at a level $\mathrm{Br}(\mathrm{o}\text{\ensuremath{-}}\mathrm{Ps}\ensuremath{\rightarrow}\text{invisible})l5.9\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$ (90% C.L.) was found.… read more here.
