| | | | | | Chiral Charge Density Waves
It was recently discovered that electrons in certain materials can conspire to make spiral patterns in their density distribution. We explain this new phenomenon as a consequence of the interactions between the different orbitals occupied by the electrons in these materials. | |  |

|  | | Observing the Divergence of Quantum Critical Fluctuations
Although it is well known that phase transition at zero temperature are accompanied by strong quantum fluctuations on all possible length scales, it is usually hard to directly observe these fluctuations in an experiment. We found that high resolution X-ray diffraction can be used to directly follow the divergence of the quantum critical fluctuations in the charge ordered material NbSe2. |

| A Nanoscale Experiment to Measure Gravity’s Influence on Quantum Mechanics
We show that the conflict between the theories of quantum mechanics and gravity may well have consequences for nanoscale experiments in the very near future. An unexpected result of their interplay is the spontaneous reduction of quantum dynamics to classical physics. | |  |
