Toward an Understanding of Parochial Observables
... This paper will focus on Ruetsche’s argument against Imperialism and Universalism,2 which I will call the problem of parochial observables. Ruetsche argues that there are certain observables, such as particle number, temperature, and net magnetization, that the Hilbert Space Conservative acquires an ...

Projections and correlations in the fractional quantum Hall effect
... These must act to create an incompressible phase at the observed fractions, or in other words to form a gap in the bulk in the absence of disorder. The strength of the interactions thus needs to be at least comparable to that of the impurities or one will only observe the integer effect. In keeping ...

Probability amplitude
In quantum mechanics, a probability amplitude is a complex number used in describing the behaviour of systems. The modulus squared of this quantity represents a probability or probability density.Probability amplitudes provide a relationship between the wave function (or, more generally, of a quantum state vector) of a system and the results of observations of that system, a link first proposed by Max Born. Interpretation of values of a wave function as the probability amplitude is a pillar of the Copenhagen interpretation of quantum mechanics. In fact, the properties of the space of wave functions were being used to make physical predictions (such as emissions from atoms being at certain discrete energies) before any physical interpretation of a particular function was offered. Born was awarded half of the 1954 Nobel Prize in Physics for this understanding (see #References), and the probability thus calculated is sometimes called the ""Born probability"". These probabilistic concepts, namely the probability density and quantum measurements, were vigorously contested at the time by the original physicists working on the theory, such as Schrödinger and Einstein. It is the source of the mysterious consequences and philosophical difficulties in the interpretations of quantum mechanics—topics that continue to be debated even today.
