Penning micro-trap for quantum computing.

Trapped ions in radio-frequency traps are among the leading approaches for realizing quantum computers, because of high-fidelity quantum gates and long coherence times. However, the use of radio-frequencies presents several challenges to scaling, including requiring compatibility of chips with high voltages, managing power dissipation and restricting transport and placement of ions. Here we realize a micro-fabricated Penning ion trap that removes these restrictions by replacing the radio-frequency field with a 3 T magnetic field.

A new polymorph of white phosphorus at ambient conditions.

Phosphorus exists in several different allotropes: white, red, violet and black. For industrial and academic applications, white phosphorus is the most important. So far, three polymorphs of white phosphorus, all consisting of P tetrahedra, have been described.

Search for Dark-Matter-Induced Oscillations of Fundamental Constants Using Molecular Spectroscopy.

A possible implication of an ultralight dark matter field interacting with the standard model degrees of freedom is oscillations of fundamental constants. Here, we establish direct experimental bounds on the coupling of an oscillating ultralight dark matter field to the up, down, and strange quarks and to the gluons, for oscillation frequencies between 10 and 10^{8}  Hz. We employ spectroscopic experiments that take advantage of the dependence of molecular transition frequencies on the nuclear masses.

Concealment of a Sexual Minority Identity in the Workplace: The Role of Workplace Climate and Identity Centrality.

Concealing a sexual minority identity at work has been linked to adverse health and employment outcomes. The authors of this paper examine whether LGBQ employee levels of concealment from coworkers and supervisors are linked to perceived workplace climate and LGBQ-identity centrality. 2010-2011 data were used; N = 319 LGBQ full or part-time employees.

Time-Resolved Spectroscopy of Photoinduced Electron Transfer in Dinuclear and Tetranuclear Fe/Co Prussian Blue Analogues.

The dynamics of the photodriven charge transfer-induced spin transition (CTIST) in two Fe/Co Prussian Blue Analogues (PBAs) are revealed by femtosecond IR and UV/vis pump-probe spectroscopy. Depending on temperature, the known tetranuclear square-type complex [CoFe(CN)(tp*)(4,4'-dtbbpy)](PF) () exists in two electronic states. In acetonitrile solution, at <240 K, the low temperature () phase is prevalent consisting of low-spin Fe(II) and low-spin Co(III), [FeCo].
