Magnetic Vortices in Gauge/Gravity Duality Dissertation by Migael Strydom Magnetic Vortices in Gauge/Gravity Duality Dissertation an der Fakult¨atf¨urPhysik der Ludwig{Maximilians{Universit¨at M¨unchen vorgelegt von Migael Strydom aus Pretoria M¨unchen, den 20. Mai 2014 Dissertation submitted to the faculty of physics of the Ludwig{Maximilians{Universit¨atM¨unchen by Migael Strydom supervised by Prof. Dr. Johanna Karen Erdmenger Max-Planck-Institut f¨urPhysik, M¨unchen 1st Referee: Prof. Dr. Johanna Karen Erdmenger 2nd Referee: Prof. Dr. Dieter L¨ust Date of submission: 20 May 2014 Date of oral examination: 18 July 2014 Zusammenfassung Wir untersuchen stark gekoppelte Ph¨anomene unter Verwendung der Dualit¨at zwischen Eich- und Gravitationstheorien. Dabei liegt ein besonderer Fokus einer- seits auf Vortex L¨osungen, die von einem magnetischem Feld verursacht werden, und andererseits auf zeitabh¨angigen Problemen in holographischen Modellen. Das wichtigste Ergebnis ist die Entdeckung eines unerwarteten Effektes in einem ein- fachen holografischen Modell: ein starkes nicht abelsches magnetisches Feld verur- sacht die Entstehung eines Grundzustandes in der Form eines dreieckigen Gitters von Vortices. Die Dualit¨at zwischen Eich- und Gravitationstheorien ist ein m¨achtiges Werk- zeug welches bereits verwendet wurde um stark gekoppelte Systeme vom Quark- Gluonen Plasma in Teilchenbeschleunigern bis hin zu Festk¨orpertheorien zu be- schreiben. Die wichtigste Idee ist dabei die der Dualit¨at: Eine stark gekoppelte Quantenfeldtheorie kann untersucht werden, indem man die Eigenschaften eines aus den Einsteinschen Feldgleichungen folgenden Gravitations-Hintergrundes be- stimmt. Eine der Gravitationstheorien, die in dieser Arbeit behandelt werden, ist ei- ne Einstein{Yang{Mills Theorie in einem AdS{Schwarzschild Hintergrund mit SU(2)-Eichsymmetrie. -
The Development of the Science of Superconductivity and Superfluidity
Universal Journal of Physics and Application 1(4): 392-407, 2013 DOI: 10.13189/ujpa.2013.010405 http://www.hrpub.org Superconductivity and Superfluidity-Part I: The development of the science of superconductivity and superfluidity in the 20th century Boris V.Vasiliev ∗Corresponding Author: [email protected] Copyright ⃝c 2013 Horizon Research Publishing All rights reserved. Abstract Currently there is a common belief that the explanation of superconductivity phenomenon lies in understanding the mechanism of the formation of electron pairs. Paired electrons, however, cannot form a super- conducting condensate spontaneously. These paired electrons perform disorderly zero-point oscillations and there are no force of attraction in their ensemble. In order to create a unified ensemble of particles, the pairs must order their zero-point fluctuations so that an attraction between the particles appears. As a result of this ordering of zero-point oscillations in the electron gas, superconductivity arises. This model of condensation of zero-point oscillations creates the possibility of being able to obtain estimates for the critical parameters of elementary super- conductors, which are in satisfactory agreement with the measured data. On the another hand, the phenomenon of superfluidity in He-4 and He-3 can be similarly explained, due to the ordering of zero-point fluctuations. It is therefore established that both related phenomena are based on the same physical mechanism. Keywords superconductivity superfluidity zero-point oscillations 1 Introduction 1.1 Superconductivity and public Superconductivity is a beautiful and unique natural phenomenon that was discovered in the early 20th century. Its unique nature comes from the fact that superconductivity is the result of quantum laws that act on a macroscopic ensemble of particles as a whole. -

Einstein and the Early Theory of Superconductivity, 1919–1922
Einstein and the Early Theory of Superconductivity, 1919–1922 Tilman Sauer Einstein Papers Project California Institute of Technology 20-7 Pasadena, CA 91125, USA [email protected] Abstract Einstein’s early thoughts about superconductivity are discussed as a case study of how theoretical physics reacts to experimental find- ings that are incompatible with established theoretical notions. One such notion that is discussed is the model of electric conductivity implied by Drude’s electron theory of metals, and the derivation of the Wiedemann-Franz law within this framework. After summarizing the experimental knowledge on superconductivity around 1920, the topic is then discussed both on a phenomenological level in terms of implications of Maxwell’s equations for the case of infinite conduc- tivity, and on a microscopic level in terms of suggested models for superconductive charge transport. Analyzing Einstein’s manuscripts and correspondence as well as his own 1922 paper on the subject, it is shown that Einstein had a sustained interest in superconductivity and was well informed about the phenomenon. It is argued that his appointment as special professor in Leiden in 1920 was motivated to a considerable extent by his perception as a leading theoretician of quantum theory and condensed matter physics and the hope that he would contribute to the theoretical direction of the experiments done at Kamerlingh Onnes’ cryogenic laboratory. Einstein tried to live up to these expectations by proposing at least three experiments on the arXiv:physics/0612159v1 [physics.hist-ph] 15 Dec 2006 phenomenon, one of which was carried out twice in Leiden. Com- pared to other theoretical proposals at the time, the prominent role of quantum concepts was characteristic of Einstein’s understanding of the phenomenon. -
Aleksei A. Abrikosov 1928–2017

Any opinions expressed in this memoir are those of the author and do not necessarily reflect the views of the National Academy of Sciences. ALEKSEI ALEKSEEVICH ABRIKOSOV June 25, 1928–March 29, 2017 Elected to the NAS, 2000 Shortly after the 2003 announcement that Aleksei Abrikosov had won the Nobel Prize in Physics, a number of colleagues took Alex to lunch at a nearby Italian restau- rant. During lunch, one of the Russian visitors exclaimed that Alex should get a second Nobel Prize, this time in Literature for his famous “AGD” book with Lev Gor’kov and Igor Dzyaloshinskii (Methods of Quantum Field Theory in Statistical Physics.) Somewhat taken aback, I looked closely at this individual and realized that he was deadly serious. Although I could imagine the reaction of the Nobel Literature committee to such a book (for a lay person, perhaps analogous to trying to read Finnegan’s Wake), I had to admit that my own copy of this book is quite dog-eared, having been put to good use over the By M. R. Norman years. In fact, you know you have made it in physics when your book gets a Dover edition. One of the most charming pictures I ever saw was a rare drawing in color that Alexei Tsvelik did (commissioned by Andrei Varlamov for Alex’s 50th birthday) that was proudly displayed in Alex’s home in Lemont, IL. It showed Alex with his fingers raised in a curled fashion as in the habit of medieval Popes. -
De Nobelprijzen Komen Eraan!
De Nobelprijzen komen eraan! De Nobelprijzen komen eraan! In de loop van volgende week worden de Nobelprijswinnaars van dit jaar aangekondigd. Daarna weten we wie in december deze felbegeerde prijzen in ontvangst mogen gaan nemen. De Nobelprijzen zijn wellicht de meest prestigieuze en bekende academische onderscheidingen ter wereld, maar waarom eigenlijk? Hoe zijn de prijzen ontstaan, en wie was hun grondlegger, Alfred Nobel? Afbeelding 1. Alfred Nobel.Alfred Nobel (1833-1896) was de grondlegger van de Nobelprijzen. Volgende week is de jaarlijkse aankondiging van de prijswinnaard. Alfred Nobel Alfred Nobel was een belangrijke negentiende-eeuwse Zweedse scheikundige en uitvinder. Hij werd geboren in Stockholm in 1833 in een gezin met acht kinderen. Zijn vader, Immanuel Nobel, was een werktuigkundige en uitvinder die succesvol was met het maken van wapens en stoommotoren. Immanuel wou dat zijn zonen zijn bedrijf zouden overnemen en stuurde Alfred daarom op een twee jaar durende reis naar onder andere Duitsland, Frankrijk en de Verenigde Staten, om te leren over chemische werktuigbouwkunde. In Parijs ontmoette bron: https://www.quantumuniverse.nl/de-nobelprijzen-komen-eraan Pagina 1 van 5 De Nobelprijzen komen eraan! Alfred de Italiaanse scheikundige Ascanio Sobrero, die drie jaar eerder het explosief nitroglycerine had ontdekt. Nitroglycerine had een veel grotere explosieve kracht dan het buskruit, maar was ook veel gevaarlijker om te gebruiken omdat het instabiel is. Alfred raakte geinteresseerd in nitroglycerine en hoe het gebruikt kon worden voor commerciele doeleinden, en ging daarom werken aan de stabiliteit en veiligheid van de stof. Een makkelijk project was dit niet, en meerdere malen ging het flink mis. -
