... For example, superconductivity is suppressed in a vortex core due to the high energy cost of supercurrents, allowing competing orders to arise in the vortex core region. As shown in Fig. 1.1, antiferromagnetism has been observed[1, 2] in the vortex cores of high-Tc cuprates. Another example is seen ...

... problem was solved by Max Planck, who published a paper in 1901, where he assumed that matter and radiation can exchange energy only in discrete quantities 10 . Using the machinery of statistical mechanics, he was able to derive the shape of the black body spectrum. The idea of quantized radiationma ...

We will not be able to discuss the threshold theorem under the most restrictive of all assumptions which can be made, but it is important to know what current methods can and cannot deal with. Of course it is a matter of physics and of engineering to determine which assumptions actually m ...

... We have assumed that the initial and final states are described by narrow wave packets with the same peak energy E 0. There exist a set of conditions on f ( E ) and the potential V which assure that this is the case, but they are stronger than those needed to assure the validity of the WKB approxima ...
