Dimerization of CO2 at High Pressure and Temperature
Dimerization of CO2 at High Pressure and Temperature Francesco Tassone,[a] Guido L. Chiarotti,[a] Roger Rousseau,[a] Sandro Scandolo,[b, c] and Erio Tosatti*[a, b, c] Dedicated to Professor Michele Parrinello on the occasion of his 60th birthday. Understanding the behavior of simple molecular systems under the combined effect of high pressure (P) and tempera- ture (T) has important implications in the modeling of planeta- ry interiors, in the chemistry of detonation, and in the synthe- sis of new materials. Extreme conditions of P and T can be par- tially accessed in the laboratory either in heated diamond-anvil cells or in shock wave experiments, where dramatic changes in the chemical and physical properties of simple molecules have been reported.[1] Depending on the detailed situation, com- pression may result in the formation of intermolecular bonds, or in disproportionation, or even in full dissociation into the constituent elements. In such a context, the theoretical predic- tion of stable or metastable structures and of their properties is highly desirable. However, this requires an accurate quantum description, capable of discriminating the often subtle changes in the nature of chemical bonds. First-principles molecular dy- namics methods with variable-cell, constant-pressure dynam- ics[2]—a natural derivation of the two revolutionary methods introduced more than 20 years ago by Michele Parrinello to- gether with Roberto Car[3] and Anees Rahman[4]—offer a unique tool for this kind of exploration. [5] Molecular CO2 was independently observed and predict- ed[6] to transform into extended quartz-like covalent solids at moderately high pressures (about 50 GPa). -
Forms of Political Representation in Late Medieval Northern Italy Merits and Shortcomings of the City-State Paradigm (Late 14Th–Early 16Th Century)
Chapter 3 Forms of Political Representation in Late Medieval Northern Italy Merits and Shortcomings of the City-State Paradigm (Late 14th–early 16th Century) Marco Gentile 1 Introduction The aim of this chapter is to provide a sketch of the varied patterns of political representation in the Lombard region at the end of the Middle Ages. More spe- cifically, this account will focus on the state or duchy of Milan, also known as the “Stato/ducato visconteo-sforzesco”. The interchangeability of these names is itself an indication of the fundamental ambiguity of the material constitu- tion of a political entity of this kind, which current historiography can choose to define either by focusing on the urban element (though Milan was not a capital city in the strict sense, nor a dominante like Venice or Florence) or by underscoring the role of the princely dynasty in power. In the late medieval Milanese duchy, there was no general representative in- stitution, such as a parliament, the German Landtage, the Cortes of Castile and Aragon, or the French provincial and general Estates. In their absence, at the centre we find bodies such as the ducal Privy Council, while at the peripheries we find the legal representative bodies of the subject cities and communities, the local councils, which were often hegemonized by semi-corporate factional groups. These different levels will be analysed here through the case studies of Parma, Piacenza and Alessandria. Until a few years ago, it was customary for historians to refer to the Mi- lanese duchy as a sum of city-states (or “a coordination of cities”) under a lord or a prince, who was a member of the Visconti, or from 1450 the Sforza dynasty.1 Over the last two decades, however, historians have begun to * I would like to thank Letizia Arcangeli, Giorgio Chittolini, Federico Del Tredici and Massimo Della Misericordia for their generous comments and suggestions on the first version of this paper. -

Finite Temperature Properties of Clusters by Replica Exchange Metadynamics: the Water Nonamer

E-mail: [email protected] Abstract We introduce an approach for the accurate calculation of thermal properties of classical nanoclusters. Based on a recently developed enhanced sampling technique, replica exchange metadynamics, the method yields the true free energy of each relevant cluster structure, di- rectly sampling its basin and measuring its occupancy in full equilibrium. All entropy sources, whether vibrational, rotational anharmonic and especially configurational – the latter often for- gotten in many cluster studies – are automatically included. For the present demonstration we arXiv:1103.0972v1 [cond-mat.stat-mech] 4 Mar 2011 choose the water nonamer (H2O)9, an extremely simple cluster which nonetheless displays a sufficient complexity and interesting physics in its relevant structure spectrum.

Ice and Victoria Buch: a Cold Surface and a Warm Heart Erio Tosatti SISSA, ICTP, and CNR/INFM Democritos, Trieste, Italy
Ice and Victoria Buch: a cold surface and a warm heart Erio Tosatti SISSA, ICTP, and CNR/INFM Democritos, Trieste, Italy Victoria Buch, who knew so much about ice and hydrogen bonds, was intrigued and fascinated by the possible physical states of the ice surface. She knew on one hand that it was only reasonable to expect the proton disorder of bulk ice to persist at the surface. She also on the other hand felt, or hoped, that the surface energetics should favor some new type of surface proton order, absent in bulk ice. To pursue this fragile dream, she stole time away from her heartier physico-chemical studies, and from her warm-hearted generous political battles within Israel, to collaborate with a surface theorist, whom she met by chance one summer in Lugano -- me. Me, who would contribute nothing more than some generic wisdom, and no actual hard calculations. Her own calculations, both Molecular Dynamics and Monte Carlo, eventually showed that in the cold ice surface not only the oxygen atoms would stay put and crystalline up until some 180 K, but showed that at low enough temperatures the protons too would order -- and that in spite of proton disorder in the underlying bulk! My own job ended up being to recognize that this surface order, 2x1 stripes formed by rows of "dangling hydrogens" and "dangling oxygens" (an old suggestion by Fletcher) could finally make sense of some unexplained helium scattering data obtained a decade earlier in Goettingen. Victoria and I were still collaborating, and spending hours on the phone at that, when her fatal disease came. -

My Random Walks in Anderson's Garden ∗ G. Baskaran The Institute of Mathematical Sciences, C.I.T. Campus, Chennai 600 113, India & Perimeter Institute for Theoretical Physics, Waterloo, ON, N2L 2Y6 Canada Abstract Anderson's Garden is a drawing presented to Philip W. Anderson on the eve of his 60th birthday celebration, in 1983. This cartoon (Fig. 1), whose author is unknown, succinctly depicts some of Andersons pre-1983 works, as a blooming garden. As an avid reader of Andersons papers, a random walk in Andersons garden had become a part of my routine since graduate school days. This was of immense help and prepared me for a wonderful collaboration with the gardener himself, on the resonating valence bond (RVB) theory of High Tc cuprates and quantum spin liquids, at Princeton. The result was bountiful - the first (RVB mean field) theory for i) quantum spin liquids, ii) emergent fermi surface in Mott insulators and iii) superconductivity in doped Mott insulators. Beyond mean field theory - i) emergent gauge fields, ii) Ginzburg Landau theory with RVB gauge fields, iii) prediction of superconducting dome, iv) an early identification and study of a non-fermi liquid normal state of cuprates and so on. Here I narrate this story, years of my gardening attempts and end with a brief summary of my theoretical efforts to extend RVB theory of superconductivity to encompass the recently observed very high Tc ∼ 203 K superconductivity in molecular solid H2S at high pressures ∼ 200 GPa. ∗ Closely follows an article published in arXiv:1608.08587v1 [cond-mat.str-el] 30 Aug 2016 PWA90 A Life Time of Emergence Editors: P. -
Glimpses of Greatness∗ a Personal View of P W Anderson (1923–2020)
GENERAL ARTICLE Glimpses of Greatness∗ A Personal View of P W Anderson (1923–2020) G Baskaran P W Anderson was a theoretical physicist. He won the No- bel Prize in 1977. He catalysed Nobel Prizes for several oth- ers. His career spanned 72 years of relentless research, filled with path-breaking contributions. He focussed on ‘here and now’ phenomena of inanimate materials and built theoreti- cal quantum models of lasting value. He communed with na- ture by contemplation and study of experimental results. As a G Baskaran is a theoretical founding father, he set agenda for the field of condensed mat- physicist. He studies a variety ter physics, for half a century. It is a growing fertile field now, of quantum phenomena, with a web of connection to different corners of science, tech- including theory and nology, and sometimes beyond.
