Application of new dynamical spectra of orbits in Hamiltonian systems

, 2012
In the present article, we investigate the properties of motion in Hamiltonian systems of two and three degrees of freedom, using the distribution of the values of two new dynamical parameters. The distribution functions of the new parameters, define the

Dynamical behaviour of a compound elastic pendulum

MATEC Web of Conferences, 2018
The aim of the paper is a comprehensive study of the compound elastic pendulum (CEP) with two degrees of freedom to point out the main complex (chaotic) dynamics that it can exhibit.

Hypernuclear No-Core Shell Model [PDF]

, 2018
We extend the No-Core Shell Model (NCSM) methodology to incorporate strangeness degrees of freedom and apply it to single-$\Lambda$ hypernuclei. After discussing the transformation of the hyperon-nucleon (YN) interaction into Harmonic-Oscillator (HO ...

Statistical equilibrium in quantum gravity: Gibbs states in group field theory

New Journal of Physics, 2018
Gibbs states are known to play a crucial role in the statistical description of a system with a large number of degrees of freedom. They are expected to be vital also in a quantum gravitational system with many underlying fundamental discrete degrees of ...

Unconstrained Hamiltonian formulation of General Relativity with thermo-elastic sources [PDF]

, 1998
A new formulation of the Hamiltonian dynamics of the gravitational field interacting with(non-dissipative) thermo-elastic matter is discussed. It is based on a gauge condition which allows us to encode the six degrees of freedom of the ``gravity + matter'

New soliton, kink and periodic solutions for fractional space–time coupled Schrödinger equation

Alexandria Engineering Journal
This work investigates the time–space fractional coupled nonlinear Schrödinger equation. By applying an appropriate wave transformation, this equation is converted into a fourth-order system of ordinary differential equations, equivalent to a Hamiltonian

Reducing or enhancing chaos using periodic orbits

, 2006
A method to reduce or enhance chaos in Hamiltonian flows with two degrees of freedom is discussed. This method is based on finding a suitable perturbation of the system such that the stability of a set of periodic orbits changes (local bifurcations ...

Persistence of invariant torus in Hamiltonian systems with two-degree of freedom

Journal of Mathematical Analysis and Applications, 2008
Consider the following Hamiltonian dynamical system: \(.{q}=H_p(p,q), \quad .{p}=-H_q(p,q)\) where the Hamiltonian function is \(H=h(p)+f(q,p)\). The classical KAM theorem asserts that if \(h\) is not degenerate i.e. det\((h_{pp})\neq 0\) then most of the invariant tori can persist when \(f\) is sufficiently small.

2D Magnetic and Topological Quantum Materials and Devices for Ultralow Power Spintronics

Advanced Functional Materials, EarlyView.
2D magnets and topological quantum materials enable ultralow‐power spintronics by combining robust magnetic order with symmetry‐protected, Berry‐curvature‐driven transport. Fundamentals of 2D anisotropy and spin‐orbit‐coupling induced band inversion are linked to scalable growth and vdW stacking.
