Magnetic Monopole Noise
This thesis presents the first ever measurement of the noise emitted by magnetic monopoles and the development of an exquisitely sensitive magnetic-field-noise spectrometer based on a superconducting quantum interference device (SQUID) that enabled it. Magnetic monopoles are highly elusive elementary particles exhibiting quantized magnetic charge. The prospects for studying them brightened recently with the theoretical discovery that the thermally excited states in certain classes of magnetic insulators exhibit all the characteristics of magnetic monopoles. Furthermore, in 2018, it was predicted that the random motion of magnetic monopoles inside would generate a very specific kind of magnetization noise. In this thesis, the author describes a new experimental technique, so-called spin noise spectroscopy, and the subsequent discovery of virtually all of the predicted features of the magnetic noise expected from a dense fluid of magnetic monopoles in crystals of Dy2Ti2O7. Remarkably, because this magnetic monopole noise occurs in the frequency range below 20kHz, when amplified by the SQUID it is actually audible to humans.
The Magick of Physics
An award-winning Oxford physicist draws on classic sci-fi, fantasy fiction, and everyday phenomena to explain and celebrate the magical properties of the world around us. If you were to present the feats of modern science to someone from the past, those feats would surely be considered magic. Theoretical physicist Felix Flicker proves that they are indeed magic—just familiar magic. The name for this magic is “condensed matter physics.” Most people haven’t heard of the field, yet more than a third of physicists identify as condensed matter researchers, making it the most active area in the subject—with good reason. Condensed matter is the solids, liquids, and gasses that surround us...
The Magick of Matter
As heard on BBC Radio 4 Start The Week 'Felix Flicker brilliantly reveals the secrets behind the modern-day magic we call physics' Marcus du Sautoy Imagine you had a crystal that lit upon your command: magic must be at work, and you must surely be a wizard. But what if you discovered that you routinely cast such spells? Are the spells no longer magic ... or are you a wizard? The modern term for wizardry is condensed matter physics. It is the study of the world around us - the states of matter and how they emerge from the quantum realm. Thanks to its practical magic we can make lasers which cut through solid metal, trains which hover in mid-air, and crystals which light our homes. It is one of the best-kept secrets in science; a third of all physicists work on it, yet its story has never been told. Join Felix Flicker as he introduces the magic of condensed matter physics. It will be a journey that reveals the subtle spells that conjure crystals from chaos and create new particles that have never before existed. The Magick of Matter will revolutionise what you know about physics and reality; you'll never see the world in the same way again.
凝態物理
你知道嗎？ 冰晶形成、LED發光，甚至最近掀起熱潮的半導體運算 都與凝態物理有關！ ◎認識凝態物理的第一本書 想像按一下鈕，就能讓一塊水晶發光，又或者敲一下水晶，就能產生火花——這可不是奇幻小說的情節，現實世界裡，這些現象就是常用的LED燈還有火鍋店裡的打火槍。要了解這些特性從何而來，首先必須了解什麼是凝態物理。 凝態物理：從平凡物質中迸出的奇妙特性 我們所見的世界由小至原子、電子，甚至夸克等等的粒子所組成，當這些粒子凝聚起來，有時會產生一些從單一粒子角度難以解釋的現象。凝態物...
Doing Business 2018
Fifteen in a series of annual reports comparing business regulation in 190 economies, Doing Business 2018 measures aspects of regulation affecting 10 areas of everyday business activity: •Starting a business •Dealing with construction permits •Getting electricity •Registering property •Getting credit •Protecting minority investors •Paying taxes •Trading across borders •Enforcing contracts •Resolving insolvencyThese areas are included in the distance to frontier score and ease of doing business ranking. Doing Business also measures features of labor market regulation, which is not included in these two measures. The report updates all indicators as of June 1, 2017, ranks e...
The Educational Heritage of Ancient India
Just a thousand years ago, India was dotted with universities across its length and breadth, where international students flocked to gain credentials in advanced education. This illustrated book describes how these multi-disciplinary centers of learning existed in several forms such as forest universities, brick-and-mortar universities and temple universities. It examines the funding for these citadels of learning and their graduation ceremonies. The process by which India’s ancient systems of education helped to fuel a knowledge revolution around the world with its manuscripts, forming the basis for monographs and academic papers, is explained with references. The marauding incursions by Muslim invaders, which disrupted the idyllic world of university learning in India, followed by European colonization, which led to further erosion and degeneration of India’s traditional learning systems, have been taken up in some detail. Readers will get a snapshot view of India's education system down the ages from ancient to modern times.
