Characterization of low-frequency electric potential oscillations near the edge of a plasma confined by a levitated magnetic dipole
A vertically adjustable electrostatic probe array was made to observe the previously seen low-frequency angular oscillations in LDX and identify if they are related to computationally expected convective cells. The array rests one meter from the centerline and measures edge fluctuations at field …

Measurement of a Weak Transition Moment Using Coherent Control
… of the transition moment of the highly-forbidden magnetic dipole transition between the 6s<sup>2</sup>S<sub>1/2</sub>1/2 and 7s<sup>2</sup>S<sub>1/2</sub>1/2 states in atomic Cesium. The experimental principle is based on a two-pathway excitation, using two phase-coherent laser fields, a …

Designing Particle Tracking Software for a Theoretical Understanding of Magnetic Janus Particle Aggregation
<p>Magnetic Janus particles are spherical colloids covered with a thin magnetic cap on one half of their surface. The asymmetric magnetic material gives the particles a magnetic dipole shifted away from the center of mass of the particle. The magnetic dipole either points perpendicular …

Electromagnetic probing of the lunar interior in the frequency region from one kilohertz to ten kilohertz
For probable values of the lunar electromagnetic properties, a transverse magnetic surface wave may be propagated along the solar wind plasma-moon interface in the frequency range from about one kilohertz to about ten kilohertz. The horizontal propagation characteristics of this surface wave as a …

Ultracold ²³Na⁶Li molecules in the triplet ground state
… NaLi is a fermionic molecule with an electric dipole moment of 0.2 Debye and a magnetic dipole moment of 2 [mu]B in its triplet ro-vibrational ground state. The formation of an ultracold molecule with both electric and magnetic dipole moments allows for novel opportunities in control of …

Photonuclear reactions near threshold
… which indicates that electric quadupole and magnetic dipole absorption of photons account for a large part of the reation yield, although electric dipole absorption may account for most of the reaction at higher energies.

MEASUREMENT OF THE MAGNETIC AND ELECTRIC DIPOLE MOMENTS OF THE $\LAMBDA$ BARYON AT LHCB
… to probe such sources is to search for electric dipole moments (EDMs) of fundamental particles. This thesis explores that possibility through the study of the \Lz baryon: an EDM observation with the current sensitivities would constitute evidence of CP violation beyond the SM. Moreover, the …
