A hierarchy of Hamilton operators and entanglement

open access: yesOpen Physics, 2009
Abstract We consider a hierarchy of Hamilton operators Ĥ N in finite dimensional Hilbert spaces $$ \mathbb{C}^{2^N } $$. We show that the eigenstates of Ĥ N are fully entangled for N even. We also calculate the unitary operator U N(t) = exp(—Ĥ

Qualitative and quantitative evaluation of the usability of transport ventilators using eye tracking [PDF]

open access: yesScientific Reports
Deficiencies in the usability of transport ventilators may lead to operating errors and patient harm. Intuitively operable devices and optimized ergonomics can reduce cognitive workload and critical events.

On local spectral properties of Hamilton operators

open access: yesFilomat, 2018
This paper deals with local spectral properties of Hamilton type operators. The strongly decomposability, Weyl type theorems and hyperinvariant subspace problem of them and the similar properties with their adjoint operators are studied. As corollaries, some local spectral properties of Hamilton operators are obtained.

Rotation in four dimensions via generalized Hamilton operators

open access: yesKuwait Journal of Science, 2013
In this paper, after a brief review of some algebraic properties of generalized quaternions, we investigated the properties of generalized Hamilton operators and we considered how the generalized quaternions can be used to described the rotation in 4 ...

A Hamilton–Jacobi-based proximal operator

open access: yesProceedings of the National Academy of Sciences, 2023
First-order optimization algorithms are widely used today. Two standard building blocks in these algorithms are proximal operators (proximals) and gradients. Although gradients can be computed for a wide array of functions, explicit proximal formulas are known for only limited classes of functions.

Noether Symmetry Method for Hamiltonian Mechanics Involving Generalized Operators

open access: yesAdvances in Mathematical Physics, 2021
Based on the generalized operators, Hamilton equation, Noether symmetry, and perturbation to Noether symmetry are studied. The main contents are divided into four parts, and every part includes two generalized operators.

Variational approach to the construction of discrete mathematical model of the pendulum motion with vibrating suspension with friction [PDF]

open access: yesИзвестия высших учебных заведений: Прикладная нелинейная динамика, 2022
The main purpose of this work is, first, a construction of the indirect Hamilton’s variational principle for the problem of motion of a pendulum with a vibration suspension with friction, oscillating along a straight line making a small angle with ...

L∞-error estimates of a finite element method for Hamilton-Jacobi-Bellman equations with nonlinear source terms with mixed boundary condition

open access: yesDemonstratio Mathematica, 2021
In this paper, we introduce a new method to analyze the convergence of the standard finite element method for Hamilton-Jacobi-Bellman equation with noncoercive operators with nonlinear source terms with the mixed boundary conditions.

Revisiting Schrödinger’s fourth-order, real-valued wave equation and the implication from the resulting energy levels

open access: yesRoyal Society Open Science, 2023
In his seminal part IV, Annalen der Physik vol. 81, 1926 paper, Schrödinger has developed a clear understanding about the wave equation that produces the correct quadratic dispersion relation for matter-waves and he first presents a real-valued wave ...
