... phonon model from the appendix. One sees that in the case of electrons the results of the DC phonon model exceed the results of the bulk phonon model roughly by a factor of one to three. This difference deserves a more detailed discussion as it contradicts the expectation (see p 2078 in [6]) accordi ...

Quantum Behavior of Measurement Apparatus - HAL-ENS
... The measurement apparatus plays an important role not only in quantum physics experiments, by providing information about the measured system, but also in the foundations of quantum theory by leading to the famous measurement problem [1, 2]. This one is in part linked to our ability to prepare the m ...

Quantum monodromy in the two-centre problem Waalkens
... Published 7 May 2003 Online at stacks.iop.org/JPhysA/36/L307 Abstract Using modern tools from the geometric theory of Hamiltonian systems it is shown that electronic excitations in diatoms which can be modelled by the two-centre problem exhibit a complicated case of classical and quantum monodromy. ...
