Quantum Behavior of Measurement Apparatus - HAL-ENS
... The measurement apparatus plays an important role not only in quantum physics experiments, by providing information about the measured system, but also in the foundations of quantum theory by leading to the famous measurement problem [1, 2]. This one is in part linked to our ability to prepare the m ...

1 Why do we need position operator in quantum theory?
... the amplitude a(x) has a sharp maximum near x = x0 ∈ [x1 , x2 ] such that a(x) is not small only when x ∈ [x1 , x2 ]. Then ∆x is of the order x2 − x1 and the condition that the coordinate is semiclassical is ∆x |x0 |. Since −ih̄dψ(x)/dx = p0 ψ(x) − ih̄exp(ip0 x/h̄)da(x)/dx, we see that ψ(x) will b ...

Randomness and Multi-level Interactions in Biology1
... As for “biological complexity”, the first point to understand within this frame is that, whatever may be increasing (the notions of biological complexity are multivariate and controversial), the dynamics of the increase do not follow a direction towards a final result (a total order). It may be a p ...

The spins are modified due pffiffiffi þ y to the occupation factors (e.g., S ¼ m aa= 2) but a transition remains. Conclusions.—We have considered the Feshbach problem for tw ...
