Erio Tosatti
Erio Tosatti (born 9 November 1943 in Nonantola) is an Italian theoretical physicist active at the International School for Advanced Studies (SISSA), and at the Abdus Salam International Centre for Theoretical Physics (ICTP), both in Trieste, Italy. He is a broad-scope theorist who carried out research on a wide range of condensed matter physics phenomena. His early work dealt with optical properties, electron energy loss, theory of excitons and nonlocal dielectric response in solids, including layer crystals such as graphite and semiconductors; charge- and spin-density-waves; surface physics in all its aspects, particularly reconstruction, roughening and melting, also in clusters; the prediction the Berry phase in fullerene; the first calculated STM map of graphite, now a standard in the field; matter at extreme pressures: carbon, oxygen, hydrogen, , iron at earth core conditions, water and ammonia at deep planetary conditions, pressure-induced insulator-metal transitions in ...

Nonantola
Nonantola ( Modenese: ) is a town and ''comune'' in the province of Modena in the Emilia-Romagna region of northern Italy. It is in the Po Valley about from Modena on the road to Ferrara. History In ancient times the territory of Nonantola was inhabited by the Celtic tribes, more specifically by the Boii. After the Roman conquest of Northern Italy (Cisalpine Gaul) the Boii were subjugated, and as a result they started to slowly speak Latin, giving rise to the local Gallo-Romance language, a variety of Gallo-Italic languages. Nonantola's history is strongly connected to the Benedictine monastery founded by the Lombards. Its creation in 752 totally supplanted the old Roman past and was the premise of Nonantola's High Middle Ages importance, as it was chosen for the meeting in 883 between Pope Marinus I and the emperor Charles the Fat. Pope Hadrian III was buried here. In the year 890 the town and the monastery were devastated by Hungarian marauders. Nonantola was disputed ...

Molybdenum Disulfide
Molybdenum disulfide (or moly) is an inorganic compound composed of molybdenum and sulfur. Its chemical formula is . The compound is classified as a transition metal dichalcogenide. It is a silvery black solid that occurs as the mineral molybdenite, the principal ore for molybdenum.Sebenik, Roger F. ''et al''. (2005) "Molybdenum and Molybdenum Compounds", ''Ullmann's Encyclopedia of Chemical Technology''. Wiley-VCH, Weinheim. is relatively unreactive. It is unaffected by dilute acids and oxygen. In appearance and feel, molybdenum disulfide is similar to graphite. It is widely used as a dry lubricant because of its low friction and robustness. Bulk is a diamagnetic, indirect bandgap semiconductor similar to silicon, with a bandgap of 1.23 eV. Single layer sheets act as a perfect mirror, reflecting 100% of incident photons. Production MoS2 is naturally found as either molybdenite, a crystalline mineral, or jordisite, a rare low temperature form of molybdenite. Molybdenite or ...

Opera
Opera is a form of theatre in which music is a fundamental component and dramatic roles are taken by singers. Such a "work" (the literal translation of the Italian word "opera") is typically a collaboration between a composer and a librettist and incorporates a number of the performing arts, such as acting, scenery, costume, and sometimes dance or ballet. The performance is typically given in an opera house, accompanied by an orchestra or smaller musical ensemble, which since the early 19th century has been led by a conductor. Although musical theatre is closely related to opera, the two are considered to be distinct from one another. Opera is a key part of the Western classical music tradition. Originally understood as an entirely sung piece, in contrast to a play with songs, opera has come to include numerous genres, including some that include spoken dialogue such as ''Singspiel'' and ''Opéra comique''. In traditional number opera, singers employ two styles o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Research Laboratory
A research institute, research centre, research center or research organization, is an establishment founded for doing research. Research institutes may specialize in basic research or may be oriented to applied research. Although the term often implies natural science research, there are also many research institutes in the social science as well, especially for sociological and historical research purposes. Famous research institutes In the early medieval period, several astronomical observatories were built in the Islamic world. The first of these was the 9th-century Baghdad observatory built during the time of the Abbasid caliph al-Ma'mun, though the most famous were the 13th-century Maragheh observatory, and the 15th-century Ulugh Beg Observatory. The Kerala School of Astronomy and Mathematics was a school of mathematics and astronomy founded by Madhava of Sangamagrama in Kerala, India. The school flourished between the 14th and 16th centuries and the original discoveries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Physiology
The human body is the structure of a human being. It is composed of many different types of cells that together create tissues and subsequently organ systems. They ensure homeostasis and the viability of the human body. It comprises a head, hair, neck, trunk (which includes the thorax and abdomen), arms and hands, legs and feet. The study of the human body involves anatomy, physiology, histology and embryology. The body varies anatomically in known ways. Physiology focuses on the systems and organs of the human body and their functions. Many systems and mechanisms interact in order to maintain homeostasis, with safe levels of substances such as sugar and oxygen in the blood. The body is studied by health professionals, physiologists, anatomists, and by artists to assist them in their work. Composition The human body is composed of elements including hydrogen, oxygen, carbon, calcium and phosphorus. These elements reside in trillions of cells and non-cellular compo ...

Quantum Computing
Quantum computing is a type of computation whose operations can harness the phenomena of quantum mechanics, such as superposition, interference, and entanglement. Devices that perform quantum computations are known as quantum computers. Though current quantum computers may be too small to outperform usual (classical) computers for practical applications, larger realizations are believed to be capable of solving certain computational problems, such as integer factorization (which underlies RSA encryption), substantially faster than classical computers. The study of quantum computing is a subfield of quantum information science. There are several models of quantum computation with the most widely used being quantum circuits. Other models include the quantum Turing machine, quantum annealing, and adiabatic quantum computation. Most models are based on the quantum bit, or "qubit", which is somewhat analogous to the bit in classical computation. A qubit can be in a 1 or 0 quantu ...

Quantum Annealing
Quantum annealing (QA) is an optimization process for finding the global minimum of a given objective function over a given set of candidate solutions (candidate states), by a process using quantum fluctuations. Quantum annealing is used mainly for problems where the search space is discrete (combinatorial optimization problems) with many local minima; such as finding the ground state of a spin glass or the traveling salesman problem. The term "quantum annealing" was first proposed in 1988 by B. Apolloni, N. Cesa Bianchi and D. De Falco as a quantum-inspired classical algorithm. It was formulated in its present form by T. Kadowaki and H. Nishimori ( ja) in "Quantum annealing in the transverse Ising model" though an imaginary-time variant without quantum coherence had been discussed by A. B. Finnila, M. A. Gomez, C. Sebenik and J. D. Doll, in "Quantum annealing is a new method for minimizing multidimensional functions". Quantum annealing starts from a quantum-mechanical superp ...
