Orbit flip magnetic transitions
Nuclear Physics, 1962Abstract In well deformed nuclei it sometimes happens that a magnetic transition between two nuclear single particle (Nilsson) states depends only on the orbit flip of the particle. Two M4 transitions, one in Hf179 and one in Yb177, which correspond to such a case were investigated and were found to be inhibited by factors of 2000 and more than 500 ...

BIFURCATION OF ROUGH HETEROCLINIC LOOP WITH ORBIT FLIPS
International Journal of Bifurcation and Chaos, 2012In 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.

Degenerate Orbit Flip Homoclinic Bifurcations with Higher Dimensions
Acta Mathematica Sinica, English Series, 2006For higher dimensional systems, bifurcations of a degenerate homoclinic orbit with orbit flip are studied. By establishing local coordinates near the homoclinic orbit, conditions are given sufficient for the existence and uniqueness of a 1-homoclinic orbit and a 1-periodic orbit.

DEGENERATE BIFURCATIONS OF HETERODIMENSIONAL CYCLES WITH ORBIT FLIP
International Journal of Bifurcation and Chaos, 2013In this paper, nongeneric bifurcation analysis near heterodimensional cycles with orbit flip is investigated for three-dimensional systems. With the aid of a suitable local coordinate system, the Poincaré map is constructed. By means of the bifurcation equations, the existence, nonexistence, coexistence and uniqueness of homoclinic orbit, periodic ...

Chaos from orbit-flip homoclinic orbits generated in real systems
Proceedings of ISCAS'95 - International Symposium on Circuits and Systems, 2002A 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 ...

Accurate Spin–Orbit Coupling by Relativistic Mixed-Reference Spin-Flip-TDDFT
Journal of Chemical Theory and Computation, 2023Relativistic mixed-reference spin-flip (MRSF)-TDDFT is developed considering the spin-orbit coupling (SOC) within the mean-field approximation. The resulting SOC-MRSF faithfully reproduces the experiments with very high accuracy, which is also consistent with the values by four-component (4c) relativistic CASSCF and 4c-CASPT2 in the spin-orbit-energy ...

The microscopic origin of spin-orbit mediated spin-flips
Journal of Magnetism and Magnetic Materials, 2020Abstract Laser induced ultrafast demagnetization is a powerful process by which the magnetic moment of a material can be modified on femtosecond timescales. However, to eventually utilize this process in technology, it is crucial that we develop a thorough understanding of the physical mechanisms involved.
