Aleksei A. Abrikosov 1928–2017
Aleksei A. Abrikosov 1928–2017 A Biographical Memoir by M. R. Norman ©2018 National Academy of Sciences. 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. -

In the year 1941, he successfully applied quantum Prof. Dr. Binil Aryal theory to the movement of superfluid liquid helium. Landau argued for the need of yet another radical conceptual revolution in physics in order to resolve the Advisory Board mounting difficulties in relativistic quantum theory. The collective work of Prof. Dr. Om Prakash Niraula Landau’s group embraced practically every branch of theoretical physics. In 1946 Prof. Dr. Raju Khanal he described the phenomenon of Landau damping of electromagnetic waves in Prof. Dr. Narayan Prasad Adhikari plasma. Together with Vitaly L. Ginzburg, in 1950 Landau obtained the correct Prof. Dr. Ram Prasad Regmi equations of the macroscopic theory of superconductivity. During the 1950s he and Prof. Dr. Ishwar Koirala collaborators discovered that even in renormalized quantum electrodynamics, a Dr. Hari Prasad Lamichhane new divergence difficulty appears (the Landau pole).

In Memory of Leo P. Kadanoff
Journal of Statistical Physics manuscript No. (will be inserted by the editor) Franz J. Wegner In memory of Leo P. Kadanoff Received: Accepted: Abstract Leo Kadanoff has worked in many fields of statistical mechanics. His contributions had an enormous impact. This holds in particular for critical phe- nomena, where he explained Widom’s homogeneity laws by means of block-spin transformations and laid the basis for Wilson’s renormalization group equation. I had the pleasure to work in his group for one year. A short historically account is given. Keywords Renormalization group · Block-spin transformation · Critical phenomena · Ising Model · Duality 1 Introduction Leo Kadanoff has worked in many fields of Statistical Mechanics. He started out in working on superconductivity in a thesis under the supervi- sion of Paul Martin at Harvard. Leo and Gordon Baym developed self-consistent approximations which preserved the conservation laws[4]. They published the widely used book Conservation laws and correlation functions[34]. Gordon Baym has reviewed his time with Leo in his contribution Conservation laws and the quantum theory of transport: The early days.[3] After a number of papers related to superconductivity and transport phenom- ena he became interested in critical phenomena, where he contributed essentially. Section 2 reviews shortly the situation in this field in the fifties and sixties of the last century. Section 3 reviews the contributions of Ben Widom and Leo Kadanoff in 1965 and 1966, which were two important steps in the understanding of this field. This led to a strongly growing interest in this field (sect. 4). Finally, in 1971 Ken Wilson developed the tool to calculate explicitly the critical behavior. -

Perhaps even more intriguing possibility arises from being able to use quantum computers to simulate the behavior of other physical systems -- an exciting idea dating back to Feynman. Unfortunately, realizing a quantum computer in practice proves to be very difficult, chiefly due to the debilitating effects of decoherence plaguing all possible schemes which use microscopic degrees of freedom (such as nuclear or electronic spins) as basic building blocks. >From this perspective, topological quantum computing offers an attractive alternative by encoding quantum information in nonlocal topological degrees of freedom that are intrinsically protected from decoherence due to local noise. -

As we mentioned ahead of time, the purpose of this interview is to discuss the period during which replica symmetry breaking was developed, roughly from 1975 to 1995. To get us to that, there are a few questions on background that we would like to bring up. In your contribution to the Walter Kohn festschrift, you described how and why you chose to become a theoretical physicist1. Given that your father was himself a physicist2, was it even an option for you not to become a physicist? JR: [0:00:41] That's a very good question. Certainly, if I had discovered I was no good at it, I wouldn’t have done it. There was this strong feeling: physics was almost a religion in my family. In fact, my brother once commented that I was the one who went into the family business. I actually remember that… I envy people who went into physics because they were so drawn to the subject. For me, there was a very strong feeling that, not that it was expected of me, but that it was a way of fulfilling some kind of destiny, or I don't know what. -

Bohr's Relational Holism and the Classical-Quantum Interaction1
1 Bohr’s Relational Holism and the classical-quantum Interaction1 Mauro Dorato Department of Philosophy Communication and Media Studies University of Rome “Roma Tre”, Via Ostiense 234, 00144, Rome, Italy [email protected] 1 Introduction: a conflict in Bohr’s philosophy? Bohr’s philosophy of quantum mechanics has often been charged for what is allegedly one of its major shortcomings, namely the advocacy of an unambiguous classical/quantum distinction (let me refer to this view with the label the distinction thesis). As is well known, such a distinction is needed to defend Bohr’s view that any communicable measurement outcome must presuppose a classically describable instrument, with respect to which any reference to the quantum of action can be neglected (Bohr 1958, 4). Critics have then often insisted on the fact that the distinction in question is hopelessly vague (Bell 1987, 29) or at least strongly contextual (Ghirardi 2004), so that Bohr’s interpretation of quantum mechanics suffers from the same vagueness and adhoc-ness. The resulting problem is, allegedly, a renunciation to describe the dynamical interaction between system and apparatus in a physically precise, theoretically based and non-contextual way, and therefore to offer a much-needed solution to the measurement problem. In my paper I will present and critically discuss the main strategies that Bohr used and could have used to defend from this charge his interpretation of quantum mechanics. In particular, in the first part I will reassess the main arguments that Bohr used to advocate the 1 Thanks to Henry Folse and Jan Faye for their attentive reading of a previous draft of the paper. -

Pearce Williams Preface The University Faculty has always followed the practice of including within the faculty records a memorial resolution on the death of one of its members. The faculty modified this custom that was begun in the earliest days of Cornell University in 1938 as follows: Upon the death of a member of the University Faculty, the President or Dean of Faculty shall formally notify the Faculty at the next meeting and those present shall rise in respect for the memory of the deceased member. The Provost shall then appoint a committee to prepare an appropriate memorial statement. Such statements shall not be presented in the form of resolutions, as in the past, but shall be annually collected, edited, and printed by the University in a memorial booklet, which shall be sent to members of the Faculty, to the families of the deceased members, and shall be filed with University records. -
