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 […]

High-Q impurity photon states bounded by a photonic-band-pseudogap in an optically-thick photonic-crystal slab

Posted by dbos Caltech

Kavli Affiliate: Axel Scherer | First 5 Authors: Se-Heon Kim, Andrew Homyk, Sameer Walavalkar, Axel Scherer, | Summary: We show that, taking a two-dimensional photonic-crystal slab system as an example, surprisingly high quality factors (Q) over 10^5 are achievable, even in the absence of a rigorous photonic-band-gap. We find that the density of in-plane Bloch […]
