Description

The perspective-dependence of position and momentum uncertainties and their
correlations are studied in the framework of nonrelativistic spatiotemporal quantum
frames of reference [M. Suleymanov, I.L. Paiva, E. Cohen, Nonrelativistic
spatiotemporal quantum reference frames, Phys. Rev. A 109, 032205 (2024)]. One
of the results [M. Suleymanov, A. Carmi, E. Cohen, Uncertainties and covariances in
the framework of spatiotemporal quantum reference frames, forthcoming] is that,
even in the non-interacting case, the Heisenberg uncertainty relations of a certain
particle described by different observers do not coincide in general. What is invariant
and constant for all observers, in the current framework, is the determinant of the
frame-dependent total covariance matrix [A. Carmi, E. Cohen, Relativistic
independence bounds nonlocality, Sci. Adv. 5, eaav8370 (2019)]. A generalized
version of uncertainty relations is obtained for the relational description, affected by
the correlations between all subsystems in a chosen frame.
