We provide a mechanism by which, from a background independent model with no quantum mechanics, quantum theory arises in the same limit in which spatial properties appear. Starting with an arbitrary abstract graph as the microscopic model of spacetime, our ansatz is that the microscopic dynamics can be chosen so that 1) the model has a low low energy limit which reproduces the non-relativistic ...

Recently, from the deduction of result MIP* = RE in quantum computation, it was obtained that Quantum Field Theory (QFT) allows for different forms computation computers Mechanics (QM) does not allow. Thus, there must exist QFT representation Universe QM We explain a simple manner how by describing differences between and QM, obtain why future will require use QFT.

inhibitory effect of three benzothiazole derivatives (1, 3-benzothiazol-2-amine (bta), 6-methyl-1, 3-benzothiazol-2-amine (mbta) and 2-amino-1, 3-benzothiazole-6-thiol (tbta)) on corrosion of carbon steel has been studied using density functional theory (dft) method in gas and aqueous phases. quantum chemical parameters such as ehomo (highest occupied molecular orbital energy), elumo (lowest un...
