Exceptional points in optics and photonics

1 week ago from Science NOW

Exceptional points are branch point singularities in the parameter space of a system at which two or more eigenvalues, and their corresponding eigenvectors, coalesce and become degenerate. Such peculiar degeneracies are distinct features...

Structure of the posttranslational Sec protein-translocation channel complex from yeast

1 week ago from Science NOW

The Sec61 protein-conducting channel mediates transport of many proteins, such as secretory proteins, across the endoplasmic reticulum (ER) membrane during or after translation. Posttranslational transport is enabled by two additional...

Laser cooling of ions in a neutral plasma

1 week ago from Science NOW

Laser cooling of a neutral plasma is a challenging task because of the high temperatures typically associated with the plasma state. By using an ultracold neutral plasma created by photoionization...

Fluorine-programmed nanozipping to tailored nanographenes on rutile TiO2 surfaces

1 week ago from Science NOW

The rational synthesis of nanographenes and carbon nanoribbons directly on nonmetallic surfaces has been an elusive goal for a long time. We report that activation of the carbon (C)–fluorine (F)...

Counter-propagating charge transport in the quantum Hall effect regime

1 week ago from Science NOW

The quantum Hall effect, observed in a two-dimensional (2D) electron gas subjected to a perpendicular magnetic field, imposes a 1D-like chiral, downstream, transport of charge carriers along the sample edges....

Rovibrational quantum state resolution of the C60 fullerene

1 week ago from Science NOW

The unique physical properties of buckminsterfullerene, C60, have attracted intense research activity since its original discovery. Total quantum state–resolved spectroscopy of isolated C60 molecules has been of particularly long-standing interest....
