... supposed to be some sort of theory in which, at least from a macroscopic point of view, we average, in a quantum mechanical sense, over all possible spacetime geometries. (We do not know to what extent this description is valid microscopically.) The averaging is done, in the simplest case, with a we ...

On distinguishability, orthogonality, and violations of the second law: contradictory assumptions, contrasting pieces of knowledge
... The interplay of orthogonality, distinguishability, thermodynamics, and multiplicity of observers is quite interesting; therefore we want to discuss and analyse it in varying depth, mainly with paedagogical purposes. The paper is divided into two main parts, reflecting two main perspectives. In the ...

... It is an empirical fact that all elementary and composite particles are either fermions or bosons. These labels distinguish between behaviors of identical particles under exchange. The wave function describing a system of indistinguishable bosons remains the same when any two particles are swapped w ...

... therefore come as a surprise to learn that quantum mechanical calculations are now routinely carried out to predict accurately the physical and chemical properties of systems containing many hundreds of atoms. These calculations can predict properties such as bond-lengths, phonon frequencies, elasti ...
