... When electrons are confined to a small region of a semiconductor they form a quantum dot, and the energy and the charge on the quantum dot are quantized. It has been possible to study the transmission of electrons through a quantum dot by coupling the states in the dot to external leads via a tunnel ...
Quantum field theory and knot invariants
... • we combine them with an inner product-like thing to get the full propagator; • in the integrand, the functions U (xint , x; t0 ) and U (x0 , xint ; t − t0 ) depend only on position xint , hence live in our Hilbert space. These three features also appear in Witten’s theory. We combine partition fun ...

One can get out of them what one wants if one uses them, and it is they which have made so much unhappiness and so many paradoxes. Can one think of anything more appalling than to say that ...

Abstract
... atoms are too small to be seen with the unaided eye, and that relativistic speeds are too fast to be perceived. We also know that quantum mechanics, the language of the atom, which replaces the crisp OR of classical physics with an ambiguous AND, really describes the way the world is. (If Schroding ...

Quantum structures in general relativistic theories
... From a physical viewpoint, it is very interesting to study concrete exact solutions. The following examples are a starting point for an analysis of the classification of quantum structures in exact solutions in Einstein’s general relativity. 1. Minkowski spacetime is topologically trivial, hence the ...

... mechanical ground states of ideal systems with no confining potential are often delocalized over the whole space, while random perturbations tend to result in localized ground states [10, 11]. The transition between the delocalized and the localized regime appears to show a critical behavior in many ...
