AB  - When an electronic system has strong correlations and a large spin-orbit 
      interaction, it often exhibits a plethora of mutually competing quantum phases. 
      How a particular quantum ground state is selected out of several possibilities is 
      a very interesting question. However, equally fascinating is how such a quantum 
      entangled state breaks up due to perturbation. This important question has 
      relevance in very diverse fields of science from strongly correlated electron 
      physics to quantum information. Here we report that a quantum entangled dimerized 
      state or valence bond crystal (VBC) phase of Li2RuO3 shows nontrivial doping 
      dependence as we perturb the Ru honeycomb lattice by replacing Ru with Li. 
      Through extensive experimental studies, we demonstrate that the VBC phase melts 
      into a valence bond liquid phase of the RVB (resonating valence bond) type. This 
      system offers an interesting playground where one can test and refine our current 
      understanding of the quantum competing phases in a single compound.
