NIU Physics PhD Candidacy Exam - Spring 2017 Quantum Mechanics
... You know that the concept of potential energy is not applicable in relativistic situations. One consequence of this is that the only fully relativistic quantum theories possible are quantum field theories. However, there do exist situations where a particle’s motion is “slightly relativistic” (e.g., ...

... quantum fluctuations of the shuttle position can not be neglected. In this situation one speaks of a quantum shuttle instability. Now once an instability occurs, how can one distinguish between quantum shuttle vibrations and classical shuttle vibrations? More generally: How can one detect quantum me ...

A VISUAL TOUR OF CLASSICAL ELECTROMAGNETISM
... we can construct animations of those fields, as above, which show that motion. A more general vector field, for example the electric and magnetic fields discussed below, do not have that immediate physical interpretation of a flow field. There is no “flow” of a fluid along an electric field or magne ...

As discussed below, quantitative interpretation of the results would be simpler in samples that are thinner than the penetration depth. The samples were imaged with the ab plane parallel to the sample surface. The T c ⫽11 K sample wa ...

A History of Physics as an Exercise in Philosophy
... The average physicist is not known to have kind and warm feelings for philosophy. Many of them feel that philosophy is not very relevant to their discipline. If there is any relevance, it is one that comes after the facts. They regard the philosophy of science as an occupation for those who are beyo ...

“Magnus” force - Pacific Institute of Theoretical Physics
... However we are NOT now going to do the usual Caldeira-Leggett trick of assuming a coupling between vortex and magnons which is linear in the magnon variables. As mentioned above, this is not even true for a soliton coupled to its environment. What we need is another expansion parameter, and there is ...
