In beyond standard models like string theories with multidimensional and holographic objects or other quantum gravity theories or models. Are there additional observable in addition to the standard ones like position, spin, charge, momentum and the like? For example. Are there holographic (or other unusual) observable where you can create operators to act on the quantum state? for example Kaluza observable? Malcadamia observable? which we could add to the common Quantum Mechanics observables like position, spin, charge, momentum and the like.. But in QFT, the QM observables were no longer focused. So what is the right way to ask this in the context of QFT about new observables or operators pertaining to higher multidimensional, holographic or other exotic states.
