Semiclassical Quantization by Pade Approximant to Periodic Orbit Sums
, 1999 Periodic orbit quantization requires an analytic continuation of non-convergent semiclassical trace formulae. We propose a method for semiclassical quantization based upon the Pade approximant to the periodic orbit sums.

Spin current generation and relaxation in a quenched spin-orbit-coupled Bose-Einstein condensate
Nature Communications, 2019 Spin-orbit coupling is interesting for fundamental understanding of spin transport and quench dynamics. Here the authors demonstrate spin-current generation and its relaxation in spin-orbit-coupled Bose-Einstein condensates of Rb atoms in different spin ...

Spin-orbital phase synchronization in the magnetic field-driven electron dynamics in a double quantum dot [PDF]
, 2011 We study the dynamics of an electron confined in a one-dimensional double quantum dot in the presence of driving external magnetic fields. The orbital motion of the electron is coupled to the spin dynamics by spin orbit interaction of the Dresselhaus type.

Orbital Pumping by Magnetization Dynamics in Ferromagnets [PDF]
arXiv, 2023 We show that dynamics of the magnetization in ferromagnets can pump the orbital angular momentum, which we denote by orbital pumping. This is the reciprocal phenomenon to the orbital torque that induces magnetization dynamics by the orbital angular momentum in non-equilibrium.

Reduced dimensionality spin-orbit dynamics of CH3 + HCl ⇌ CH4 + Cl on ab initio surfaces.
Journal of Chemical Physics, 2011 A reduced dimensionality quantum scattering method is extended to the study of spin-orbit nonadiabatic transitions in the CH(3) + HCl ⇌ CH(4) + Cl((2)P(J)) reaction.

Covariant and quasi-covariant quantum dynamics in Robertson-Walker space-times [PDF]
, 2002 We propose a canonical description of the dynamics of quantum systems on a class of Robertson-Walker space-times. We show that the worldline of an observer in such space-times determines a unique orbit in the local conformal group SO(4,1) of the space ...

On the Hofer-Zehnder conjecture for non-contractible periodic orbits in Hamiltonian dynamics [PDF]
arXiv, 2021 In this paper, we treat an open problem related to the number of periodic orbits of Hamiltonian diffeomorphisms on closed symplectic manifolds. Hofer-Zehnder conjecture states that a Hamiltonian diffeomorphisms has infinitely many periodic orbits if it has "homologically unnecessary periodic orbits"".

Orbital Dynamics of Cygnus X‐3 [PDF]
The Astrophysical Journal, 2000 Orbital-phased-resolved infrared spectra of Cygnus X-3 in outburst and quiescence, including tomographic analysis, are presented. We confirm the phasing of broad HeII and NV lines in quiescence, such that maximum blue shift corresponds to the X-ray minimum at phase = 0.00 +/- 0.04.

Theory of anisotropic exchange in laterally coupled quantum dots [PDF]
, 2010 The effects of spin-orbit coupling on the two-electron spectra in lateral coupled quantum dots are investigated analytically and numerically. It is demonstrated that in the absence of magnetic field the exchange interaction is practically unaffected by ...
