full_context: Document 1: Leo Esaki: Reona Esaki (江崎 玲於奈 "Esaki Reona", born March 12, 1925), also known as Leo Esaki, is a Japanese physicist who shared the Nobel Prize in Physics in 1973 with Ivar Giaever and Brian David Josephson for his discovery of the phenomenon of electron tunneling. He is known for his invention of the Esaki diode, which exploited that phenomenon. This research was done when he was with Tokyo Tsushin Kogyo (now known as Sony). He has also contributed in being a pioneer of the semiconductor superlattices.
Document 2: Enrico Persico: Enrico Persico (August 9, 1900 – June 17, 1969) was an Italian physicist notable for propagating the field of quantum mechanics in Italy. He was a professor at the University of Turin and is also notable as the doctoral advisor of Ugo Fano.
Document 3: Enrico Fermi: Enrico Fermi ( ; ] ; 29 September 1901 – 28 November 1954) was an Italian physicist and the creator of the world's first nuclear reactor, the Chicago Pile-1. He has been called the "architect of the nuclear age" and the "architect of the atomic bomb". He was one of the very few physicists in history to excel both theoretically and experimentally. Fermi held several patents related to the use of nuclear power, and was awarded the 1938 Nobel Prize in Physics for his work on induced radioactivity by neutron bombardment and the discovery of transuranic elements. He made significant contributions to the development of quantum theory, nuclear and particle physics, and statistical mechanics.
Document 4: Emilio Segrè: Emilio Gino Segrè (1 February 1905 – 22 April 1989) was an Italian physicist and Nobel laureate who discovered the elements technetium and astatine, and the antiproton, a sub-atomic antiparticle, for which he was awarded the Nobel Prize in Physics in 1959.
Document 5: Ettore Majorana: Ettore Majorana ( ; ] ; born on 5 August 1906 – probably died after 1959) was an Italian theoretical physicist who worked on neutrino masses. On March 25, 1938, he disappeared under mysterious circumstances while going by ship from Palermo to Naples. The Majorana equation and Majorana fermions are named after him.
Document 6: Sergio Ferrara: Sergio Ferrara (born May 2, 1945) is an Italian physicist working on theoretical physics of elementary particles and mathematical physics. He is renowned for the discovery of theories introducing supersymmetry as a symmetry of elementary particles (super-Yang–Mills theories, together with Bruno Zumino) and of supergravity, the first significant extension of Einstein's general relativity, based on the principle of "local supersymmetry" (together with Daniel Z. Freedman, and Peter van Nieuwenhuizen). He is an emeritus staff member at CERN and a professor at the University of California, Los Angeles.
Document 7: Feynman diagram: In theoretical physics, Feynman diagrams are pictorial representations of the mathematical expressions describing the behavior of subatomic particles. The scheme is named after its inventor, American physicist Richard Feynman, and was first introduced in 1948. The interaction of sub-atomic particles can be complex and difficult to understand intuitively. Feynman diagrams give a simple visualization of what would otherwise be a rather arcane and abstract formula. As David Kaiser writes, "since the middle of the 20th century, theoretical physicists have increasingly turned to this tool to help them undertake critical calculations", and so "Feynman diagrams have revolutionized nearly every aspect of theoretical physics". While the diagrams are applied primarily to quantum field theory, they can also be used in other fields, such as solid-state theory.
Document 8: Massless particle: In particle physics, a massless particle is an elementary particle whose invariant mass is zero. The two known massless particles are both gauge bosons: the photon (carrier of electromagnetism) and the gluon (carrier of the strong force). However, gluons are never observed as free particles, since they are confined within hadrons. Neutrinos were originally thought to be massless. However, because neutrinos change flavor as they travel, at least two of the types of neutrinos must have mass. The discovery of this phenomenon, known as neutrino oscillation, led to Canadian scientist Arthur B. McDonald and Japanese scientist Takaaki Kajita sharing the 2015 Nobel prize in physics.
Document 9: Ugo Fano: Ugo Fano {'1': ", '2': ", '3': 'ForMemRS', '4': "} (July 28, 1912 – February 13, 2001) was an Italian American physicist, notable for contributions to theoretical physics.
Document 10: Juan Martín Maldacena: Juan Martín Maldacena (* September 10, 1968 in Buenos Aires, Argentina) is a theoretical physicist. Among his many discoveries, the most famous one is the most reliable realization of the holographic principle – namely the AdS/CFT correspondence, the conjecture about the equivalence of string theory on Anti-de Sitter (AdS) space, and a conformal field theory defined on the boundary of the AdS space. In 2013, Maldacena co-authored an analysis of the 2012 black hole firewall paradox with Leonard Susskind, arguing that the paradox can be resolved if entangled particles are connected by minor wormholes."<ref name="nytimes/Mystery Wrapped"> </ref>
Document 11: Yuen-Ron Shen: Yuen-Ron Shen (沈元壤) is a professor emeritus of physics at the University of California, Berkeley, known for his work on non-linear optics. He was born in Shanghai and graduated from National Taiwan University. He received his Ph.D. in Applied Physics from Harvard under physicist and Nobel Laureate Nicolaas Bloembergen in 1963, and joined the department of physics at Berkeley in 1964. In the early years, Dr. Shen was probably best known for his work on self-focusing and filament propagation of laser beams in materials. These fundamental studies enabled the creation of ultrafast supercontinuum light sources. In the 1970s and 1980s, he collaborated with Yuan T. Lee on the study of multiphoton dissociation of molecular clusters. The molecular-beam photofragmentation translational spectroscopy that they developed has clarified much of the initial confusion concerning the dynamics of infrared multiphoton dissociation processes. In the 1980s and 1990s, Professor Shen developed various nonlinear optics methods for the study of material surfaces and interfaces. Among these techniques, second-harmonic generation and sum frequency generation spectroscopy are best known and now widely used by scientists from various fields. He has collaborated with Gabor Somorjai on the use of the technique of Sum Frequency Generation Spectroscopy to study catalyst surfaces. He is the author of the book "The Principles of Nonlinear Optics". Professor Shen belongs to the prolific J. J. Thomson academic lineage tree. Currently, Professor Shen works in U. C. Berkeley and Fudan University in Shanghai.
Document 12: Behram Kurşunoğlu: Behram Kurşunoğlu (14 March 1922 – 25 October 2003) was a Turkish physicist and the founder and the director of the Center for Theoretical Studies, University of Miami. He was best known for his works on unified field theory, energy and global issues. Moreover, he participated in the discovery of two different types of neutrinos in late 1950s. During his University of Miami career, he hosted several Nobel Prize laureates, including Paul Dirac, Lars Onsager and Robert Hofstadter. He wrote several books on diverse aspects of physics, the most notable of which is "Modern Quantum Theory" (1962).
Document 13: Michele Limon: Michele Limon is an Italian research associate and assistant professor of Physics and Astronomy at Columbia University in the City of New York. Dr. Limon studied physics at the Università degli Studi di Milano in Milan, Italy and completed his post-doctoral work at the University of California, Berkeley. He has been conducting research for more than 20 years and has experience in the design of ground, balloon and space-based instrumentation. His academic specialties include Astrophysics, Cosmology, Instrumentation Development, and Cryogenics.
Document 14: Fano factor: In statistics, the Fano factor, like the coefficient of variation, is a measure of the dispersion of a probability distribution of a Fano noise. It is named after Ugo Fano, an Italian American physicist.
Document 15: Fano resonance: In physics, a Fano resonance is a type of resonant scattering phenomenon that gives rise to an asymmetric line-shape. Interference between a background and a resonant scattering process produces the asymmetric line-shape. It is named after Italian-American physicist Ugo Fano, who gave a theoretical explanation for the scattering line-shape of inelastic scattering of electrons from helium; however, Ettore Majorana was the first to discover this phenomenon. Because it is a general wave phenomenon, examples can be found across many areas of physics and engineering.
