Observation of Periodic Orbits on Curved Two - dimensional Geometries

Autor: Avlund, M., Ellegaard, C., Oxborrow, M., Guhr, T., Sondergaard, N.

Publikováno v: Phys. Rev. Lett. 104, 164101 (2010)

We measure elastomechanical spectra for a family of thin shells. We show that these spectra can be described by a "semiclassical" trace formula comprising periodic orbits on geodesics, with the periods of these orbits consistent with those extracted

Elasticity of macroscopic isotropic media applied to nano--cantilevers

Autor: Sondergaard, N., Ghatnekar-Nilsson, S., Guhr, T., Montelius, L.

We analyze recently measured data for the mechanical deflection of Chromium nano--cantilevers. We show that the deflection curves exhibit a scaling behavior when applying properly chosen coordinates. Moreover, the deflection curves are well described

Counting function for a sphere of anisotropic quartz

Autor: Sondergaard, N., Guhr, T., Oxborrow, M., Schaadt, K., Ellegaard, C.

Publikováno v: Phys. Rev. E 70, 036206 (2004)

We calculate the leading Weyl term of the counting function for a mono-crystalline quartz sphere. In contrast to other studies of counting functions, the anisotropy of quartz is a crucial element in our investigation. Hence, we do not obtain a simple
