Newton-Hooke type symmetry of anisotropic oscillators
P. M. Zhang, P. A. Horvathy, K. Andrzejewski +2
The rotation-less Newton--Hooke - type symmetry found recently in the Hill problem and instrumental for explaining the center-of-mass decomposition is generalized to an arbitrary a…

Exotic Hill Problem: Hall motions and symmetries
P. M. Zhang, P. A. Horvathy
Our previous study of a system of bodies assumed to move along almost circular orbits around a central mass, approximately described by Hill's equations, is extended to "exotic" [a…

Transverse Shifts in Paraxial Spinoptics
C. Duval, P. A. Horvathy, P. M. Zhang
The paraxial approximation of a classical spinning photon is shown to yield an "exotic particle" in the plane transverse to the propagation. The previously proposed and observed po…
