Lec. 42 notes
... A Λ particle with mass 1116 MeV/c2 decays at rest to a proton with mass 938 MeV/c2 and a pion with mass 140 MeV/c2. What can we say about the proton and pion momentum and energy? A. The proton and pion have the same magnitude momentum and energy. B. The proton and pion have the same energy but the p ...

Quantum mechanics of electrons in strong magnetic field
... A schematic illustration of the density of states is shown in Fig. 5. We can see from the Eq. (13) that the degeneracy of a Landau level is related to the number of the magnetic flux quantum Φ0 piercing the sample of area S in a magnetic field B. Factor 2 in the g (B) comes from the spin degree of f ...

In this paper we show for the first time, by explicit examples, that entanglement can be used to increase asymptotic zero-error capacity, even to the extent that it is equal to the Shannon capacity of the channel. This is particularly surprising in the light of the fact that the rate at which classi ...

Acoustic Measurement of Aerosol Particles

Signals originating from particle analysis experiments will have a much broader range of charateristics. For instance, for a 10 2 r ...

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.
