This file/PR defines the expectation value, centered vector, variance, and standard deviation of `T` in the state `ψ`, for a partial linear map `T` on a complex inner product space and a vector `ψ ∈ T.domain`, building on Unbounded_v2 proposal. This is PR 1 of 3 and adapts a small portion of a larger state-observable and canonical-CCR development (being carried-out at Axiomatic-AI) into physlib. Subsequent PRs will specialize this API to the position and momentum partial maps, and port the CCR uncertainty and equality-condition lemmas. Depends on leanprover-community#1090

Nice! Will likely have to wait for #1090 to be cleaned up and merged before this. |

Actually the changes of this PR seem logically independent from the changes in #1090. Could separate them out and make this PR now |

Tin the stateψ, for a partial linear mapTon a complex inner product space and a vectorψ ∈ T.domain, building on Unbounded_v2 proposal in #1090.This is PR 1 of 3 and it adapts a small portion of a larger state-observable and canonical-CCR development (from Axiomatic-AI work) into physlib.
Subsequent PRs will specialize this API to the position and momentum partial maps, and port the abstract CCR uncertainty and equality-condition lemmas.
It depends on #1090
