    "abstract": "A quantum scar is a wave function which displays an high intensity in the\nregion of a classical unstable periodic orbit. Saddle scars are states related\nto the unstable harmonic motions along the stable manifold of a saddle point of\nthe potential. Using a semiclassical method it is shown that, independently of\nthe overall structure of the potential, the local dynamics of the saddle point\nis sufficient to insure the general existence of this type of scars and their\nfactorized structure is obtained. Potentially useful situations are identified,\nwhere these states appear (directly or in disguise) and might be used for\nquantum control purposes.",
