Percolation lithography: Tuning and freezing disorder in 3D photonic crystals using partial wetting and drying

Posted by klaurent Harvard

Kavli Affiliate: Anna V. Shneidman | First 5 Authors: Ian B. Burgess, Navid Abedzadeh, Theresa M. Kay, Anna V. Shneidman, Derek J. Cranshaw | Summary: Although complex, hierarchical nanoscale geometries with tailored degrees of disorder are commonly found in biological systems, few simple self-assembly routes to fabricating synthetic analogues have been identified. We present two […]

Optimizing a Dynamical Decoupling Protocol for Solid-State Electronic Spin Ensembles in Diamond

Posted by klaurent Delft

Kavli Affiliate: Viatcheslav V. Dobrovitski | First 5 Authors: Demitry Farfurnik, Andrey Jarmola, Linh M. Pham, Zhi-Hui Wang, Viatcheslav V. Dobrovitski | Summary: We demonstrate significant improvements of the spin coherence time of a dense ensemble of nitrogen-vacancy (NV) centers in diamond through optimized dynamical decoupling (DD). Cooling the sample down to $77$ K suppresses […]

Synaptic polarity of the interneuron circuit controlling C. elegans locomotion

Posted by klaurent Caltech

Kavli Affiliate: Paul W. Sternberg | First 5 Authors: Franciszek Rakowski, Jagan Srinivasan, Paul W. Sternberg, Jan Karbowski, | Summary: C. elegans is the only animal for which a detailed neural connectivity diagram has been constructed. However, synaptic polarities in this diagram, and thus, circuit functions are largely unknown. Here, we deciphered the likely polarities […]

Study of superfluid $^3$He under nanoscale confinement. A new approach to the investigation of superfluid $^3$He films

Posted by klaurent Cornell

Kavli Affiliate: Jeevak Parpia | First 5 Authors: Lev Levitin, Robert Bennett, Andrew Casey, Brian Cowan, John Saunders | Summary: We review recent experiments in which superfluid $^3$He has been studied under highly controlled confinement in nanofluidic sample chambers. We discuss the experimental challenges and their resolution. These methods open the way to a systematic […]

Long-Lived Distributed Relative Localization of Robot Swarms

Posted by klaurent Harvard

Kavli Affiliate: Radhika Nagpal | First 5 Authors: Alejandro Cornejo, Radhika Nagpal, , , | Summary: This paper studies the problem of having mobile robots in a multi-robot system maintain an estimate of the relative position and relative orientation of near-by robots in the environment. This problem is studied in the context of large swarms […]

Generalized master equation for modular exciton density transfer

Posted by klaurent Berkeley

Kavli Affiliate: Graham Fleming | First 5 Authors: Seogjoo Jang, Stephan Hoyer, Graham Fleming, K. Birgitta Whaley, | Summary: A generalized master equation (GME) governing quantum evolution of modular exciton density (MED) is derived for large scale light harvesting systems composed of weakly interacting modules of multiple chromophores. The GME-MED offers a practical framework to […]

Higher-order defect mode laser in an optically thick photonic crystal slab

Posted by dbos Caltech

Kavli Affiliate: Axel Scherer | First 5 Authors: Se-Heon Kim, Jingqing Huang, Axel Scherer, , | Summary: The use of an optically thick slab may provide versatile solutions for the realization of a current injection type laser using photonic crystals. Here, we show that a transversely higher-order defect mode can be designed to be confined […]

Large-field-of-view Chip-scale Talbot-grid-based Fluorescence Microscopy

Posted by klaurent Caltech

Kavli Affiliate: Paul W. Sternberg | First 5 Authors: Shuo Pang, Chao Han, Mihoko Kato, Paul W. Sternberg, Changhuei Yang | Summary: The fluorescence microscope is one of the most important tools in modern clinical diagnosis and biological science. However, its expense, size and limited field-of-view (FOV) are becoming bottlenecks in key applications such as […]
