A Darwinian Uncertainty Principle. [PDF]

open access: yesSyst Biol, 2020
Abstract Reconstructing ancestral characters and traits along a phylogenetic tree is central to evolutionary biology. It is the key to understanding morphology changes among species, inferring ancestral biochemical properties of life, and recovering migration routes in phylogeography.

Uncertainty principle of quantum processes [PDF]

open access: yesPhysical Review Research, 2021
Heisenberg's uncertainty principle, which imposes intrinsic restrictions on our ability to predict the outcomes of incompatible quantum measurements to arbitrary precision, demonstrates one of the key differences between classical and quantum mechanics ...

A Quantum Wavelet Uncertainty Principle

open access: yesFractal and Fractional, 2021
In the present paper, an uncertainty principle is derived in the quantum wavelet framework. Precisely, a new uncertainty principle for the generalized q-Bessel wavelet transform, based on some q-quantum wavelet, is established. A two-parameters extension

Heisenberg's uncertainty principle [PDF]

open access: yesPhysics Reports, 2007
Heisenberg's uncertainty principle is usually taken to express a limitation of operational possibilities imposed by quantum mechanics. Here we demonstrate that the full content of this principle also includes its positive role as a condition ensuring that mutually exclusive experimental options can be reconciled if an appropriate trade-off is accepted.

Modified Unruh effect from generalized uncertainty principle [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
We consider a generalized uncertainty principle (GUP) corresponding to a deformation of the fundamental commutator obtained by adding a term quadratic in the momentum.

Product Entropic Uncertainty Principle

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki
Motivated by Deutsch entropic uncertainty principle and by various product-type uncertainty relations, we develop a new uncertainty principle that provides a rigorous lower bound on the product of entropies through the use of suitable functional ...

FUNCTIONAL DEUTSCH UNCERTAINTY PRINCIPLE

open access: yesSSRN Electronic Journal, 2023
Let $\{f_j\}_{j=1}^n$ and $\{g_k\}_{k=1}^m$ be Parseval p-frames for a finite dimensional Banach space $\mathcal{X}$. Then we show that \begin{align}\label{UE} \log (nm)\geq S_f (x)+S_g (x)\geq -p \log \left(\displaystyle\sup_{y \in \mathcal{X}_f\cap \mathcal{X}_g, \|y\|=1}\left(\max_{1\leq j\leq n, 1\leq k\leq m}|f_j(y)g_k(y)|\right)\right), \quad ...

Entropy and the uncertainty principle [PDF]

open access: yesInformation and Control, 1959
A minimum principle is obtained for the sum of entropies of two distributions related as the absolute squares of a Fourier transform pair. The minimum is shown to be attained for a Gaussian pair. The joint entropy is calculated for two other Fourier pairs of interest.
