Methods of Statistical Spectroscopy as an Optimization
Methods of Statistical Spectroscopy as an Optimization

... Schur functions (or S-functions) play a very important role in the group-theoretical/algebraic description of many-body systems. Plethysm or symmetrized product, to which B.G. Wybourne devoted a great deal of work, is an S-function operation essential in the construction of a multi-particle wave-fun ...

The history of how we ended up with background independence as a principle throughout the history of physics all the way back to the relational ideas of Mach is well recounted by Smolin in [1]. Modern gravity theories are, however, complicated. For instance in gen ...

... (2.4) should not be overlooked: equation (2.4) holds for all x(t), y(t), z(t). This seems like a trivial statement in this example but it is a crucial property of action symmetries. Symmetries can take far more complicated forms. Let q i be a set of generalised coordinates. Then for an action I[q i ...

Specifically, the theory says that in fact we live not in a 4-dimensional spacetime continuum, but rather in a 5-dimensional one, and the fifth dimension is not a hidden, folded-up, mathematical fiction, but is as real as the other four. It is the proper time, which should be treated as an independe ...

Instanton

An instanton (or pseudoparticle) is a notion appearing in theoretical and mathematical physics. An instanton is a classical solution to equations of motion with a finite, non-zero action, either in quantum mechanics or in quantum field theory. More precisely, it is a solution to the equations of motion of the classical field theory on a Euclidean spacetime.
