Information:  - In nuclear physics, beta decay (""-decay) is a type of radioactive decay in which a beta ray (fast energetic electron or positron), and a neutrino are emitted from an atomic nucleus. For example, beta decay of a neutron transforms it into a proton by the emission of an electron, or conversely a proton is converted into a neutron by emission of a positron (positron emission), thus changing the nuclide type. Neither the beta particle or its associated neutrino exist within the nucleus prior to beta decay, but are created in the decay process. By this process, unstable atoms obtain a more stable ratio of protons to neutrons. The probability of a nuclide decaying due to beta and other forms of decay is determined by its binding energy. The binding energies of all existing nuclides form what is called the nuclear valley of stability.  - Marshall Nicholas Rosenbluth (5 February 1927  28 September 2003) was an American plasma physicist and member of the National Academy of Sciences. In 1997 he was awarded the National Medal of Science for discoveries in controlled thermonuclear fusion, contributions to plasma physics, and work in computational statistical mechanics. He was also a recipient of the E.O. Lawrence Prize (1964), the Albert Einstein Award (1967), the James Clerk Maxwell Prize in Plasma Physics (1976), the Enrico Fermi Award (1985), and the Hannes Alfvén Prize (2002).  - Density functional theory (DFT) is a computational quantum mechanical modelling method used in physics, chemistry and materials science to investigate the electronic structure (principally the ground state) of many-body systems, in particular atoms, molecules, and the condensed phases. Using this theory, the properties of a many-electron system can be determined by using functionals, i.e. functions of another function, which in this case is the spatially dependent electron density. Hence the name density functional theory comes from the use of functionals of the electron density. DFT is among the most popular and versatile methods available in condensed-matter physics, computational physics, and computational chemistry.  - Statistical mechanics is a branch of theoretical physics using probability theory to study the average behaviour of a mechanical system, where the state of the system is uncertain.  - Hungary is a unitary parliamentary republic in Central Europe. It covers an area of , situated in the Carpathian Basin and bordered by Slovakia to the north, Romania to the east, Serbia to the south, Croatia to the southwest, Slovenia to the west, Austria to the northwest, and Ukraine to the northeast. With about 10 million inhabitants, Hungary is a medium-sized member state of the European Union. The official language is Hungarian, which is the most widely spoken Uralic language in the world. Hungary's capital and largest metropolis is Budapest, a significant economic hub, classified as an Alpha- global city. Major urban areas include Debrecen, Szeged, Miskolc, Pécs and Gyr.  - The River Hamble is a river in Hampshire, England. It rises near Bishop's Waltham and flows for some 7.5 miles (12 km) through Botley, Bursledon and Swanwick before entering Southampton Water near Hamble-le-Rice and Warsash.  - Southampton, on the south coast of England, is the largest city in the ceremonial county of Hampshire. It is south-west of London and north-west of Portsmouth. Southampton is a major port and the closest city to the New Forest. It lies at the northernmost point of Southampton Water at the confluence of the Rivers Test and Itchen, with the River Hamble joining to the south of the urban area. The city, which is a unitary authority, has an estimated population of 253,651. The city's name is sometimes abbreviated in writing to "So'ton" or "Soton", and a resident of Southampton is called a .  - Hampshire (; abbreviated Hants, archaically known as the County of Southampton) is a county on the southern coast of England in the United Kingdom. The county town of Hampshire is Winchester, the former capital city of England. Hampshire is the most populous ceremonial county in the United Kingdom (excluding the metropolitan counties) with almost half of the county's population living within the South Hampshire conurbation which includes the cities of Southampton and Portsmouth. The larger South Hampshire metropolitan area has a population of 1,547,000. Hampshire is notable for housing the birthplaces of the Royal Navy, British Army, and Royal Air Force. It is bordered by Dorset to the west, Wiltshire to the north-west, Berkshire to the north, Surrey to the north-east, and West Sussex to the east. The southern boundary is the coastline of the English Channel and the Solent, facing the Isle of Wight.  - Professor Hermann Arthur Jahn ( born 31 May 1907 , Colchester , England ; d. 24 October 1979 Southampton ) was an English scientist of German origin . With Edward Teller , he identified the Jahn - Teller effect .  - Nicholas Constantine Metropolis (Greek: , June 11, 1915  October 17, 1999) was a Greek-American physicist.  - Enrico Fermi (29 September 1901  28 November 1954) was an Italian physicist, who created 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 few physicists 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.  - The JahnTeller effect (JT effect or JTE) is an important mechanism of spontaneous symmetry breaking in molecular and solid-state systems which has far-reaching consequences for different fields, and it is related to a variety of applications in spectroscopy, stereochemistry and crystal chemistry, molecular and solid-state physics, and materials science.  - Physics (from , from "phúsis" "nature") is the natural science that involves the study of matter and its motion and behavior through space and time, along with related concepts such as energy and force. One of the most fundamental scientific disciplines, the main goal of physics is to understand how the universe behaves.  - Edward Teller (January 15, 1908  September 9, 2003) was a Hungarian-American theoretical physicist who was born in Hungary, and is known colloquially as "the father of the hydrogen bomb", although he claimed he did not care for the title. He made numerous contributions to nuclear and molecular physics, spectroscopy (in particular, the JahnTeller and RennerTeller effects) and surface physics. His extension of Enrico Fermi's theory of beta decay, in the form of GamowTeller transitions, provided an important stepping stone in its application, while the JahnTeller effect and the BrunauerEmmettTeller (BET) theory have retained their original formulation and are still mainstays in physics and chemistry. Teller also made contributions to ThomasFermi theory, the precursor of density functional theory, a standard modern tool in the quantum mechanical treatment of complex molecules. In 1953, along with Nicholas Metropolis, Arianna Rosenbluth, Marshall Rosenbluth, and Augusta Teller, Teller co-authored a paper which is a standard starting point for the applications of the Monte Carlo method to statistical mechanics.  - Molecular physics is the study of the physical properties of molecules, the chemical bonds between atoms as well as the molecular dynamics. Its most important experimental techniques are the various types of spectroscopy; scattering is also used. The field is closely related to atomic physics and overlaps greatly with theoretical chemistry, physical chemistry and chemical physics.  - Portsmouth is a port city in the ceremonial county of Hampshire on the south coast of England. Located mainly on Portsea Island, south-west of London and south-east of Southampton, it is the United Kingdom's only island city. It has a population of 205,400, and is the only city in the British Isles with a greater population density than London. The city forms part of the South Hampshire built-up area, which also covers Southampton and the towns of Havant, Waterlooville, Eastleigh, Fareham, and Gosport.
