From Chemistry to Consciousness: The Legacy of Hans Primas by Harald Atmanspacher,Ulrich Müller-Herold PDF

By Harald Atmanspacher,Ulrich Müller-Herold

This e-book displays at the major and hugely unique medical contributions of Hans Primas. A professor of chemistry at ETH Zurich from 1962 to 1995, Primas persevered his learn actions until eventually his demise in 2014. Over those 50 years and extra, he labored at the foundations of nuclear magnetic resonance spectroscopy, contributed to a couple of major concerns in theoretical chemistry, helped to elucidate crucial issues in quantum concept and the philosophy of physics, advised cutting edge methods of addressing interlevel kinfolk within the philosophy of technology, and brought state-of-the-art methods within the flourishing younger box of clinical reviews of attention. His paintings in those parts of study and its carrying on with influence is defined via famous specialists, colleagues, and collaborators of Primas. All authors contextualize their contributions to facilitate the mutual conversation among those fields.

Bob Coecke,David Moore,Alexander Wilce's Current Research in Operational Quantum Logic: Algebras, PDF

By Bob Coecke,David Moore,Alexander Wilce

the current quantity has its origins in a couple of casual workshops held on the loose college of Brussels, in June of 1998 and should of 1999, named "Current learn 1 in Operational Quantum Logic". those introduced jointly mathematicians and physicists operating in operational quantum good judgment and similar parts, in addition to a couple of philosophers of technology, for an extraordinary chance to debate fresh advancements during this box. After a few dialogue, it used to be made up our minds that, instead of generating a quantity of convention lawsuits, we might try and set up the conferees to supply a suite of complete survey papers, which might not just record on contemporary advancements in quantum good judgment, but additionally supply an academic review of the topic appropriate for an non-specialist viewers. The ensuing quantity offers an outline of the thoughts and strategies utilized in present examine in quantum good judgment, considered either as a department of mathemati­ cal physics and as a space of natural arithmetic. the 1st 1/2 the booklet is worried with the algebraic part of the topic, and specifically the idea of orthomodular lattices and posets, impact algebras, and so forth. within the moment 1/2 the e-book, distinctive awareness is given to express equipment and to connections with theoretical machine technology. on the 1999 workshop, we have been lucky to listen to 3 first-class lectures by means of David J. Foulis, represented right here by means of contributions. Dave's paintings, spanning forty years, has helped to outline, and keeps to reshape, the sector of quantum logic.

Eman lectures on Quantum Physics shumi de ryoushirikigaku - download pdf or read online

By Hiroe Katsuhiko

「波?粒子? いや、どちらでもない それは100年も前の説明だ」
「自然界は複素数の論理を使って動いている」

『趣味で量子力学』の電子書籍版です。
 固定レイアウト形式で、一部デザイン(ページ番号位置やページ上部)の違いの他はほとんど同じ構成になっています。ページ番号も紙版と同じですので紙版との違いを意識せずに互いに議論できるようになっています。

 量子力学を本気で学びたい人のために数式を使って丁寧に説明しています。 著者は好奇心旺盛な高校生に本気で本物の量子力学を教えるつもりで書いています。 必要な数学はその都度説明しているので、高校の物理や数学の知識があれば読み進めることができるでしょう。
 難しいと感じる部分は慌てて理解しようとせず、読み飛ばして先へ進むくらいの気軽さでチャレンジされることを期待しています。 どこかでつまづくとその先が読めなくなるという書き方ではありません。 実際に、後のほうが簡単だったりもします。

 普通の教科書ではかなり後ろの方で説明されることの多い原子の構造の話をいきなり第1章で説明し終えていたり、複素数の話を差し挟んでいたり、量子力学の考え方に疑いを抱いて反抗を企ててみたりと、ちょっと珍しい構成になっています。 しかし内容はかなり正統な量子力学の考え方に沿ったものですので安心して下さい。 初学者が抱くであろう、早く先のことを知りたい気持ちに応え、次々と思い浮かぶであろう疑いの気持ちを晴らすような理論的考察を含んでいます。

 この本を読んで初めて波数の考え方が分かったとか、フーリエ解析の考え方が分かったなどという感想も寄せられており、量子力学以外の分野の理解にも役に立つかもしれません。

Read e-book online Tunneling Dynamics in Open Ultracold Bosonic Systems: PDF

By Axel U. J. Lode

This thesis addresses the fascinating subject of the quantum tunnelling of many-body structures similar to Bose-Einstein condensates. regardless of the large volume of labor at the tunneling of a unmarried particle via a barrier, we all know little or no about how a approach made from numerous or of many debris tunnels via a barrier to open space. The present work uses numerically particular ideas of the time-dependent many-boson Schrödinger equation to discover the wealthy physics of the tunneling to open house approach in ultracold bosonic debris which are before everything ready as a Bose-Einstein condensate and therefore allowed to tunnel via a barrier to open area. The many-body strategy is outfitted up from concurrently occurring unmarried particle methods which are characterised via various momenta. those momenta correspond to the chemical potentials of structures with lowering particle quantity. The many-boson approach shows interesting collective phenomena: the escaping particles fragment and lose their coherence with the resource and between one another, while correlations build up within the process. The special knowing of the many-body strategy is used to plan and try a scheme to manage the ultimate country, momentum distributions or even the correlation dynamics of the tunneling process.
