Geometric phase for mixed states: a differential geometric approach [PDF]
The European Physical Journal C, 2003 A new definition and interpretation of geometric phase for mixed state cyclic unitary evolution in quantum mechanics are presented. The pure state case is formulated in a framework involving three selected Principal Fibre Bundles, and the well known ...

Fusing Wearable IMUs With Multi-View Images for Human Pose Estimation: A Geometric Approach [PDF]
Computer Vision and Pattern Recognition, 2020 We propose to estimate 3D human pose from multi-view images and a few IMUs attached at person's limbs. It operates by firstly detecting 2D poses from the two signals, and then lifting them to the 3D space. We present a geometric approach to reinforce the

Comparing fuel-optimal and shortest paths with obstacle avoidance
Aviation, 2022 This paper presents a comparison of fuel-optimal and shortest paths of an unmanned combat aerial vehicle (UCAV) with obstacle avoidance. A nonlinear constrained optimization algorithm is applied to obtain the optimal paths. An initial value problem (IVP)

Geometric approach to inhomogeneous Floquet systems [PDF]
Physical review B, 2020 We present a new geometric approach to study Floquet many-body systems described by inhomogeneous conformal field theory in 1+1 dimensions. By encoding the time evolution into coordinate transformations, we show existence of heating phases characterized ...

Sensitivity analysis of cassava mosaic disease with saturation incidence rate model
AIMS Mathematics, 2023 Cassava mosaic disease (CMD) is caused by a virus transmitted by the whitefly. This disease can destroy cassava at any stage of its growth and it resulted in lower cassava yields.

Geometric Approach to Quantum Statistical Inference [PDF]
IEEE Journal on Selected Areas in Information Theory, 2020 We study quantum statistical inference tasks of hypothesis testing and their canonical variations, in order to review relations between their corresponding figures of merit—measures of statistical distance—and demonstrate the crucial differences which ...

Geometric Approaches to Persistent Homology
SIAM Journal on Applied Algebra and Geometry, 2022 We introduce several geometric notions, including the width of a homology class, to the theory of persistent homology. These ideas provide geometric interpretations of persistence diagrams. Indeed, we give quantitative and geometric descriptions of the "life span" or "persistence" of a homology class. As a case study, we analyze the power filtration on
