Keywords: Ultracold physics; BEC; Supersolid theory (5940520721).jpg Artistic rendition of a supersolid made from two different types of ultracold atoms The atoms are arranged in a regularly repeating pattern like a solid but also can move frictionlessly like a superfluid Yellow shape represents the electrical forces that the atoms feel which vary in a regular pattern Correspondingly the density of the atoms represented by the thickness of the spheres also varies in a periodic fashion Credit Ludwig Mathey NIST/JQI Disclaimer Any mention of commercial products within NIST web pages is for information only; it does not imply recommendation or endorsement by NIST Use of NIST Information These World Wide Web pages are provided as a public service by the National Institute of Standards and Technology NIST With the exception of material marked as copyrighted information presented on these pages is considered public information and may be distributed or copied Use of appropriate byline/photo/image credits is requested https //www flickr com/photos/usnistgov/5940520721/ Ultracold physics; BEC; Supersolid theory 2009-01-13 12 09 https //www flickr com/people/63059536 N06 National Institute of Standards and Technology PD-USGov National Institute of Standards and Technology https //flickr com/photos/63059536 N06/5940520721 2016-09-07 02 12 48 United States Government Work Ultracold atoms |
