Chaos in Axially Symmetric Potentials with Octupole Deformation
, 1994 Classical and quantum mechanical results are reported for the single particle motion in a harmonic oscillator potential which is characterized by a quadrupole deformation and an additional octupole deformation.

Spatially periodic radio-frequency quadrupole focusing linac
Physical Review Special Topics. Accelerators and Beams, 2015 The new design for a spatially periodical rf quadrupole focusing linac is proposed. It consists of accelerating gaps formed between conventional cylindrical drift tubes, between drift tubes and rf quadrupoles with nonzero axial potential, and inside ...

Dynamic Multipole Polarizabilities of Helium and Screened-Helium Atoms
Atoms, 2020 The precise estimation of atomic polarizabilities impinges upon a number of areas and processes in physical science. We calculate precisely the dynamic multipole polarizabilities of the helium and screened-helium atoms using highly correlated exponential

Long-range forces between two excited mercury atoms and associative ionization
, 2007 The long-range quadrupole-quadrupole ($\sim R^{-5}$) and leading dispersion ($\sim R^{-6}$) interactions between all pairs of excited Hg($6s6p$) $^3P_0$, $^3P_1$, $^3P_2$, and $^1P_1$ atoms are determined. The quadrupole moments are calculated using the {

Developing a field independent frequency reference
New Journal of Physics, 2015 We show that by averaging over transitions to multiple hyperfine levels, quadrupole shifts and dominant Zeeman effects exactly cancel whenever the nuclear spin, I , is at least as large as the total electronic angular momentum, J .

Ellipsoidal Coulomb Crystals in a Linear Radiofrequency Trap
, 2004 A static quadrupole potential breaks the cylindrical symmetry of the effective potential of a linear rf trap. For a one-component fluid plasma at low temperature, the resulting equilibrium charge distribution is predicted to be an ellipsoid.

CMB-induced Cluster Polarization as a Cosmological Probe [PDF]
, 2003 Scattering of the temperature anisotropy quadrupole by free electrons in galaxy clusters leads to a secondary polarization signal in the cosmic microwave background (CMB) fluctuations.

, 2017 (shortened) We determine the transformation matrix T that maps multiple images with resolved features onto one another and that is based on a Taylor-expanded lensing potential close to a point on the critical curve within our model-independent lens ...
