“Relative State” Formulation of Quantum Mechanics

Can the change with time of the state of the total system be described by Process 2? If so, then it wou ...

Transport Electron through a Quantum Wire by Side-Attached Asymmetric Quantum-Dot Chains
... Figure 3.a, N=3 and M=4 are set for first and second chains. It is clear that the sum of dots in two-chains (N+M) determines the number of anti-resonances in conductance spectrum and it is independent of the value of p. In other words, the number of mini gaps matches exactly the number of QDs chains ...

Bohr–Einstein debates
The Bohr–Einstein debates were a series of public disputes about quantum mechanics between Albert Einstein and Niels Bohr. Their debates are remembered because of their importance to the philosophy of science. An account of the debates was written by Bohr in an article titled ""Discussions with Einsteinon Epistemological Problems in Atomic Physics"". Despite their differences of opinion regarding quantum mechanics, Bohr and Einstein had a mutual admiration that was to last the rest of their lives.The debates represent one of the highest points of scientific research in the first half of the twentieth century because it called attention to an element of quantum theory, quantum non-locality, which is absolutely central to our modern understanding of the physical world. The consensus view of professional physicists has been that Bohr proved victorious, and definitively established the fundamental probabilistic character of quantum measurement.
