Modified Types of Quantum Uncertainty Relations |
In General
> s.a. correlations; deformed uncertainty
relations; phenomenology of quantum uncertainties [including relativistic particles].
* Arbitrary self-adjoint
operators: Applying the Schwarz inequality to \(f := A - \langle A \rangle\)
and \(g:= B - \langle B \rangle\), one can derive that
\[ \Delta A\, \Delta B \ge {\textstyle{1\over2}}|\langle[A, B]\rangle|\;.\]
* Robertson uncertainty principle: If A1, ..., AN are complex self-adjoint matrices and ρ a density matrix, then the quantum generalized covariance is bounded in terms of the commutators [Ah, Aj] by
det (covρ(Ah, Aj)) ≥ det (− \({\rm i}\over2\)tr (ρ [Ah, Aj])) .

Thermodynamic Uncertainty Relation
* Idea:
A definite temperature can be attributed only to a system submerged in a heat bath,
in which case energy fluctuations are unavoidable, while a definite energy can
be assigned only to systems in thermal isolation, thus excluding the simultaneous
determination of its temperature; In general, the situation is intermediate.
* History: Bohr and Heisenberg
suggested that T and U are complementary in the same way as position
and momentum in quantum mechanics; Rosenfeld extended this analogy and obtained a
quantitative uncertainty relation in the form \(\Delta U\,\Delta(1/T) \ge k_{_{\rm B}}\) ;
The two extreme cases of this relation would then characterize the complementarity
between isolation (U definite) and contact with a heat bath (\(T\) definite);
Other formulations of the thermodynamical uncertainty relations were proposed by
Mandelbrot (1956, 1989), Lindhard (1986), and Lavenda (1987, 1991).
