Light speed reduction to 17 metres per second in an ultracold atomic gas
Lene Vestergaard Hau,Lene Vestergaard Hau,Stephen E. Harris,Zachary Dutton,Zachary Dutton,Cyrus H. Behroozi,Cyrus H. Behroozi +6 more
TL;DR: In this paper, an experimental demonstration of electromagnetically induced transparency in an ultracold gas of sodium atoms, in which the optical pulses propagate at twenty million times slower than the speed of light in a vacuum, is presented.
Journal ArticleDOI
Electromagnetically Induced Transparency
TL;DR: Electromagnetic induced transparency is a technique for eliminating the effect of a medium on a propagating beam of electromagnetic radiation EIT may also be used, but under more limited conditions, to eliminate optical self-focusing and defocusing and to improve the transmission of laser beams through inhomogeneous refracting gases and metal vapors, as figure 1 illustrates.
Journal ArticleDOI
Identification of the haematopoietic stem cell niche and control of the niche size
Jiwang Zhang,Chao Niu,Ling Ye,Haiyang Huang,Xi C. He,Wei Gang Tong,Jason Ross,Jeffrey S. Haug,Teri Johnson,Jian Q. Feng,Stephen E. Harris,Leanne M. Wiedemann,Leanne M. Wiedemann,Yuji Mishina,Linheng Li,Linheng Li +15 more
TL;DR: It is concluded that SNO cells lining the bone surface function as a key component of the niche to support HSCs, and that BMP signalling through BMPRIA controls the number of H SCs by regulating niche size.
Journal ArticleDOI
Observation of electromagnetically induced transparency.
TL;DR: In this paper, the authors report the first demonstration of a technique by which an optically thick medium may be rendered transparent by applying a temporally smooth coupling laser between a bound state of an atom and the upper state of the transition which is to be made transparent.
Proceedings Article
Observation of electromagnetically induced transparency
TL;DR: The first demonstration of a technique by which an optically thick medium may be rendered transparent is reported, which results from a destructive interference of two dressed states created by applying a temporally smooth coupling laser between a bound state of an atom and the upper state of the transition which is to be made transparent.
