An Atomic Linear Stark Shift Violating P But Not T Arising From the Electroweak Nuclear Anapole Moment [PDF]

, 2001
We propose a direct method of detection of the nuclear anapole moment. It is based on the existence of a linear Stark shift for alkali atoms in their ground state perturbed by a quadrupolar interaction potential and a magnetic field.

Ni and Mo enrichment mechanisms in framboidal pyrite during methane-release events (Baiyun Sag, South China Sea)

Frontiers in Marine Science
Framboidal pyrite, a common form of authigenic pyrite in marine sediments, forms through the co-precipitation of equant, equidimensional microcrystals that can effectively sequester trace elements.

Photoluminescence Blinking beyond Quantum-Confinement: Spatiotemporally Correlated Intermittency over Entire Micron Sized Perovskite Polycrystalline Disks

, 2018
Abrupt fluorescence intermittency or blinking is long recognized to be characteristic of single nano-emitters. Extended quantum-confined nanostructures also undergo spatially heterogeneous blinking, however, there is no such precedence in dimensionally ...
