We investigate the possibility that a background independent quantum theory of gravity is not a theory of quantum geometry. We provide a way for global spacetime symmetries to emerge from a background independent theory without geometry. In this, we use a quantum information theoretic formulation of quantum gravity and the method of noiseless subsystems in quantum error correction. This is also...

We present selected results for the Holstein molecular crystal model in one space dimension as determined by the Global-Local variational method, including complete polaron energy bands, ground state energies, and effective masses. We juxtapose our results with specific comparable results of numerous other methodologies of current interest, including quantumMonte Carlo, cluster diagonalization,...

corporations have a key role in economic development, growth of national security and financial competition. the key of power is in economy. so in the global village, the economic competition replaces military conflict. a new concept in criminal justice is corporate crime. these crimes as a kind of white collar crime are studied in light of critical criminology findings of this study shows that...
