Chaos from orbit-flip homoclinic orbits generated in a practical circuit.

Physical Review Letters, 1995
A new class of chaotic systems is generated in a practical, nonlinear, mutually coupled phase-locked loop (PLL) circuit. Theoretical results make it possible to understand experimental results of such PLL's on the onset of chaos using the geometry of the invariant manifolds, while the resultant simple geometry and complex dynamics is expected to have ...

Spin–flip manipulation in HgTe/CdTe heterostructure interface states with Rashba and Dresselhuas spin–orbit interactions

, 2021
We investigate theoretically the electron transport through (001) HgTe/CdTe quantum well heterostructures with inverted-band in planar geometry, where Dirac-like spin–momentum locked interface states have been predicted to be formed and topologically ...

Spin-Orbit Torque Nonvolatile Flip-Flop Designs

2021 IEEE International Symposium on Circuits and Systems (ISCAS), 2021
Flip-flops (FFs) are basic units in electronic circuits. Recently, nonvolatile FFs (NVFFs) have attracted great interests for power-gating applications and a variety of NVFFs have been proposed by integrating nonvolatile memory devices. Among them, magnetic tunnel junction (MTJ) based NVFFs show considerable potential in terms of zero static power ...

BIFURCATION OF ROUGH HETEROCLINIC LOOP WITH ORBIT FLIPS

International Journal of Bifurcation and Chaos, 2012
In this paper, heteroclinic loop bifurcations with double orbit flips are investigated in four-dimensional vector fields. We obtain the bifurcation equations by setting up a local coordinate system near the rough heteroclinic orbit and establishing the Poincaré map.

Homoclinic Bifurcation of Orbit Flip with Resonant Principal Eigenvalues

Acta Mathematica Sinica, English Series, 2005
The authors consider the general 4-dimensional system in a resonant orbit flip situation. The resonance takes place between the two principal eigenvalues. This is a kind of codimension-3 bifurcation. The authors obtain the existence, number, coexistence of the 1-homoclinic orbit, 1-periodic orbit and 2-homoclinic orbit, etc.

Chaos from orbit-flip homoclinic orbits generated in real systems

Proceedings of ISCAS'95 - International Symposium on Circuits and Systems, 2002
A new class of chaotic systems is discovered that are generated in a practical, nonlinear, mutually coupled phase-locked loop (PLL) circuit. Presented theoretical results make it possible to understand experimental results of mutually coupled PLL's on the onset of chaos using the geometry of the invariant manifolds, while the resultant simple geometry ...

Ferromagnetic model system with spin-orbit coupling: Dynamical gap and effective spin-flip scattering

Journal of Magnetism and Magnetic Materials, 2019
We investigate ultrafast magnetization dynamics due to electron-phonon interaction in a ferromagnetic Rashba model, which includes spin-orbit coupling and a Stoner mean-field splitting.
