Rigged Hilbert spaces, often known as Gelfand triplets, extend the standard Hilbert space framework to incorporate both square-integrable states and more singular objects such as generalised ...

Perhaps the most beautiful aspect of mathematics is that it applies to literally everything, even things that do not exist in this Universe. In addition to this there are a number of alternative ways ...

Spontaneous collapse models of state vector reduction represent a possible solution to the quantum measurement problem. In the present paper we focus our attention on the Ghirardi–Rimini–Weber (GRW) ...
