2023/11/13
In this talk we introduce some improved Caffarelli-Kohn-Nirenberg inequalities and uncertainty principle for complex- and vector-valued functions on ?n, which is a further study of the results given i...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Uncertainty from the Perspective of Resource
资源视角 不确定性 量子力学 不确定性
2023/5/6
The uncertainty is a historic topic in quantum mechanics. In this talk, we view the uncertainty as the intrinsic property of quantum states and study it from the perspective of resource.
A FRAMEWORK FOR POSITION UNCERTAINTY OF UNORGANISED THREE-DIMENSIONAL POINT CLOUDS FROM NEAR-MONOSTATIC LASER SCANNERS USING COVARIANCE ANALYSIS
Position uncertainty Three-dimensional Point Cloud Laser Scanning
2015/8/13
Position uncertainty is one of the most important quantities of an unorganised three-dimensional point clouds since it
provides the confidence level of any parametric estimation such as surface...
After the lecture: Extra dimensions, interacting dark matter, and the power of uncertainty
After the lecture Extra dimensions interacting dark matter the power of uncertainty
2015/4/30
In her most recent book, physicist Lisa Randall--Harvard professor, libretto composer, Lego figurine, star in the world of theoretical physics--writes that the universe repeatedly reveals itself ...
Persistence and Uncertainty in the Academic Career
Persistence Uncertainty Academic Career Physics and Society
2012/4/19
Understanding how institutional changes within academia may affect the overall potential of science requires a better quantitative representation of how careers evolve over time. Since knowledge spill...
Some methods of estimating uncertainty in accident reconstruction
estimating uncertainty accident reconstruction Gauss statistical method
2011/8/5
Abstract: In the paper four methods for estimating uncertainty in accident reconstruction are discussed: total differential method, extreme values method, Gauss statistical method, and Monte Carlo sim...
First considerations on the generalized uncertainty principle for finite-dimensional discrete phase spaces
First considerations the generalized uncertainty principle finite-dimensional discrete phase spaces
2011/7/27
Abstract: Generalized uncertainty principle and breakdown of the spacetime continuum certainly represent two important results derived of various approaches related to quantum gravity and black hole p...
Lorentz invariance, nonzero minimal uncertainty in position, and inhomogeneity of space at the Planck scale
Lorentz invariance nonzero minimal uncertainty
2010/12/24
The suspicion that the existence of a minimal uncertainty in position measurements violates Lorentz invariance seems unfounded. It is shown that the existence of such a nonzero minimal uncertainty in...
Black hole entropy divergence and the uncertainty principle
Black hole entropy divergence uncertainty principle
2010/11/11
Black hole entropy has been shown by 't Hooft to diverge at the horizon. The region near the horizon is in a thermal state, so entropy is linear to energy which consequently also diverges. We find a s...
Uncertainty Relation Revisited from Quantum Estimation Theory
Uncertainty Relation Revisited Quantum Estimation Theory
2010/11/5
By invoking quantum estimation theory we formulate the uncertainty relation for arbitrary quantum states and measurements in a finite-dimensional Hilbert space. To obtain information about the quantum...
Uncertainty related to position and momentum localization of a quantum state
Uncertainty related position momentum localization quantum state
2010/11/5
This paper presents the uncertainty related to position and momentum localization of a quantum state in terms of entropic uncertainty relations. We slightly improve the inequality given in [Phys. Rev....
From Low-Distortion Norm Embeddings to Explicit Uncertainty Relations and Efficient Information Locking
uncertainty relations information locking low-distortion norm embedding
2010/11/5
We exploit a connection between uncertainty relations and low-distortion embeddings of L2 into L1, which allows us to adapt an explicit low-distortion embedding to obtain efficient entropic uncertaint...
Schrödinger uncertainty relation, Wigner-Yanase-Dyson skew information and metric adjusted correlation measure
Trace inequality Wigner-Yanase-Dyson skew information
2010/10/29
In this paper, we give a Schr\"odinger-type uncertainty relation using the Wigner-Yanase-Dyson skew information. In addition, we give Schr\"odinger-type uncertainty relation by use of a two-parameter...
Uncertainty relations give upper bounds on the accuracy by which the outcomes of two incompatible measurements can be predicted. While the established uncertainty relations apply to cases where the pr...
