Surface topology specific metasurface holograms
(2018-05-16) - Journal articleMetasurface holograms are usually realized on flat surface topologies. Here we show that flexible holographic metasurfaces can be designed to form an image when applied to arbitrary substrate shapes. We demonstrate that ... -
Tracking dark excitons with exciton-polaritons in semiconductor microcavities
(2019-01-09) - Journal articleDark excitons are of fundamental importance for a wide variety of processes in semiconductors, but are difficult to investigate using optical techniques due to their weak interaction with light fields. We reveal and ... -
Fluorescence spectrum and thermalization in a driven coupled cavity array
(2019-01-02) - Journal articleWe calculate the fluorescence spectra of a driven lattice of coupled cavities. To do this, we extend methods of evaluating two-time correlations in infinite lattices to open quantum systems; this allows access to momentum ... -
ATP-induced asymmetric pre-protein folding as a driver of protein translocation through the Sec machinery
(2019-01-02) - Journal articleTransport of proteins across membranes is a fundamental process, achieved in every cell by the 'Sec' translocon. In prokaryotes, SecYEG associates with the motor ATPase SecA to carry out translocation for pre-protein ... -
Dual quantum confinement and anisotropic spin splitting in the multi-valley semimetal PtSe2
(2019-01-10) - Journal articleWe investigate the electronic structure of a two-dimensional electron gas created at the surface of the multi-valley semimetal 1T-PtSe2. Using angle-resolved photoemission and rst-principles-based surface space charge ...
