This book provides an interesting snapshot of recent advances in the field of single molecule nanosensing. The ability to sense single molecules, and to precisely monitor and control their motion is crucial to build a microscopic understanding of key processes in nature, from protein folding to chemical reactions. Recently a range of new techniques have been developed that allow single molecule sensing and control without the use of fluorescent labels. This volume provides an overview of recent advances that take advantage of micro- and nanoscale sensing technologies and provide the prospect for rapid future progress. The book endeavors to provide basic introductions to key techniques, recent research highlights, and an outlook on big challenges in the field and where it will go in future. It is a valuable contribution to the field of single molecule nanosensing and it will be of great interest to graduates and researchers working in this topic.
Confinement and manipulation of photons using microcavities have triggered intense research interest in both basic and applied physics for more than a decade. Prominent examples are whispering gallery microcavities which confine photons by means of continuous total internal reflection along a curved and smooth surface. The long photon lifetime, strong field confinement, and in-plane emission characteristics make them promising candidates for enhancing light-matter interactions on a chip. In this book, we will introduce different ultra-high-Q whispering gallery microcavities, and focus on their applications in enhancing light-matter interaction, such as ultralow-threshold microlasing, highly sensitive optical biosensing, nonlinear optics, cavity quantum electrodynamics and cavity optomechanics.
This thesis presents an experimental study of quantum memory based on cold atomic ensembles and discusses photonic entanglement. It mainly focuses on experimental research on storing orbital angular momentum, and introduces readers to methods for storing a single photon carried by an image or an entanglement of spatial modes. The thesis also discusses the storage of photonic entanglement using the Raman scheme as a step toward implementing high-bandwidth quantum memory. The storage of photonic entanglement is central to achieving long-distance quantum communication based on quantum repeaters and scalable linear optical quantum computation. Addressing this key issue, the findings presented in the thesis are very promising with regard to future high-speed and high-capacity quantum communications.
*** Note to instructors. This book is available free of charge as an eBook on Perusall, the peer discussion forum. *** This unique textbook on nonlinear optics is written by award-winning teacher and researcher, Regents Professor Mark G. Kuzyk of Washington State University. It is ideal for a class or as a reference, and can be used for self study. Exercises are provided as material is introduced to reinforce concepts. The book's approach mirrors the author's philosophy that a firm grounding in the fundamentals will allow the student to tackle any topic. As such, many topics are left out while others are covered in depth to develop the intuition. Physics is meant to be savored, so this book ...
This thesis presents experimental research on the interaction between the optical field and the mechanical oscillator in whispering-gallery mode microcavities. It demonstrates how optomechanical interactions in a microresonator can be used to achieve non-magnetic non-reciprocity and develop all-optically controlled non-reciprocal multifunctional photonic devices. The thesis also discusses the interaction between the travelling optical and mechanical whispering-gallery modes, paving the way for non-reciprocal light storage as a coherent, circulating acoustic wave with a lifetime of up to tens of microseconds. Lastly, the thesis presents a high-frequency phase-sensitive heterodyne vibrometer, operating up to 10 GHz, which can be used for the high-resolution, non-invasive mapping of the vibration patterns of acoustic devices. The results presented here show that optomechanical devices hold great potential in the field of information processing.
A VITAL NEXT CHAPTER IN THE ONGOING CONVERSATION ABOUT RACE AND SOCIAL JUSTICE IN AMERICA When he was in his early twenties, William Juneboy Outlaw iii was sentenced to eighty-five years in prison for homicide and armed assault. The sentence brought his brief but prolific criminal career as the head of a forty-member cocaine gang in New Haven, Connecticut, to a close. But behind bars, Outlaw quickly became a feared prison “shot caller” with 100 men under his sway. Then everything changed: His original sentence was reduced by sixty years. At the same time, he was shipped to a series of America’s most notorious federal prisons, where he endured long stints in solitary confinement—and w...
Evidence-Based Orthopedics is an up-to-date review of the best evidence for the diagnosis, management, and treatment of orthopedic conditions. Covering orthopedic surgery as well as pre- and post-operative complications, this comprehensive guide provides recommendations for implementing evidence-based practice in the clinical setting. Chapters written by leading clinicians and researchers in the field are supported by tables of evidence that summarize systematic reviews and randomized controlled trials. In areas where evidence is insufficient to recommend a practice, summaries of the available research are provided to assist in decision-making. This fully revised new edition reflects the mos...
