Atomic Structure and the Periodic Table
... The first two quantum numbers (n and l) describe electrons that have different energies under normal circumstances in multi-electron atoms. The last two quantum numbers (ml , ms) describe electrons that have different energies only under special conditions, such as the presence of a strong magnetic ...

Reflections on the four facets of symmetry: how physics
... symmetry revitalises and clarifies the long-standing philosophical debate between realists and their opponents. The notions of “reality”, “being”, “existence” or even “self” have always been tricky because one cannot define them without introducing some tautology. In the endless controversial discussi ...

Classical Field Theory - Imperial College London
... However, as these examples show, we will still encounter fields representing one type of particle yet which have several components. This is essential because sometimes what we call a single type of particle, a photon, an electron and which we represent with a single field, actually comes in several v ...

Theory of fluctuations in a network of parallel superconducting wires
... about 4 Å) are superconducting with a transition temperature of 15 K [1,2]. Because these tubes are so thin, they behave very much like one-dimensional superconductors. It was therefore proposed [1] that they could be described by a complex order parameter w(z) which varies only in one dimension, sa ...

Electron shell contributions to gamma

Figure 3(b) shows the individual orbital contributions to the γ -ray spectrum of Ar. The outer valence shell indeed behaves very differently from the shells wit ...

String Theory 101 - King`s College London
... has quite a few parameters which are only fixed by experimental observation. What fixes these? It postulates a certain spectrum of fundamental particle states but why these? In particular these particle states form three families, each of which is a copy of the others, differing only in their masses ...

Comparisons between classical and quantum mechanical

Adding more lasers makes it possible to create lattices, not only simple types with higher dimensionality, but also of a more complex character, e.g. moving lattices, kagome la ...
