On the significance of electromagnetic potentials in the quantum theory

[r]

- (Theorem 4.2) In absence of diagonal noise, the pure off-diagonal noise still drives the diagonal density matrix elements (called the populations) to final values as t → ∞, at a

We also mention that, for (finitedimensional) Hamilton–Dirac systems, an analogue of the Wigner function can be defined; its evolution is described by the system of

intermediate states. Quite generally in the large class of two-dimensional systems investigated in this and our previous [4, 11] articles the disorder induced

Abstract. This supports the arguments that the long range order in the ground state is reached by a spontaneous symmetry breaking, just as in the classical case...

The standard model of partile physis is a quantum eld theory of gauge elds and.. matter in

Trie point of view adopted in this paper is that the Quantum Hall Effect observed in the FISDW phases is reasonably well described within a weak couphng approach I assume that

Considering that the electromagnetic field is a special case of the gravitational field [10], the structure of which has the character of a standing gravitational wave for
