Jiří Horáček (physicist)
Prof. RNDr. Jiří Horáček, DrSc. (* February 2, 1945 in Nová Paka) is a Czech theoretical physicist, professor at Charles University in Prague, where he works at the Institute of Theoretical Physics, which is a part of the Faculty of Mathematics and Physics. He was the director of the Institute in 2003–2011. He works in the field of theoretical atomic and molecular physics with a special focus on numerical solutions to integral and differential equations of scattering theory and on numerical analytic continuation methods localizing the poles of scattering quantities related to resonances. Life Jiří Horáček spent his early life in Nová Paka. His mother Marta Horáčková (née Pátá) was a music teacher. In early youth he started playing violin. His teacher was a famous music virtuoso Josef Muzika. Although Jiří Horáček later pursued a different subject, violin has always been an important part of his life and he performs regularly with a music group Four ...

Theoretical Physics
Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain, and predict List of natural phenomena, natural phenomena. This is in contrast to experimental physics, which uses experimental tools to probe these phenomena. The advancement of science generally depends on the interplay between experimental studies and theory. In some cases, theoretical physics adheres to standards of mathematical rigour while giving little weight to experiments and observations.There is some debate as to whether or not theoretical physics uses mathematics to build intuition and illustrativeness to extract physical insight (especially when normal experience fails), rather than as a tool in formalizing theories. This links to the question of it using mathematics in a less formally rigorous, and more intuitive or heuristic way than, say, mathematical physics. For example, while developing special relativity, Albert E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Method Of Continued Fractions
The method of continued fractions is a method developed specifically for solution of integral equations of quantum scattering theory like Lippmann–Schwinger equation or Faddeev equations. It was invented by Jiří Horáček (physicist), Horáček and Sasakawa in 1983. The goal of the method is to solve the integral equation : , \psi\rangle = , \phi\rangle + G_0 V, \psi\rangle iteratively and to construct convergent continued fraction for the T-matrix : T= \langle \phi , V , \psi\rangle . The method has two variants. In the first one (denoted as MCFV) we construct approximations of the potential energy operator V in the form of finite rank operator, separable function of rank 1, 2, 3 ... The second variant (MCFG method) constructs the finite rank approximations to Green's operator. The approximations are constructed within Krylov subspace constructed from vector , \phi\rangle with action of the operator A=G_0 V. The method can thus be understood as resummation of (in general diverge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quantum Mechanics
Quantum mechanics is the fundamental physical Scientific theory, theory that describes the behavior of matter and of light; its unusual characteristics typically occur at and below the scale of atoms. Reprinted, Addison-Wesley, 1989, It is the foundation of all quantum physics, which includes quantum chemistry, quantum field theory, quantum technology, and quantum information science. Quantum mechanics can describe many systems that classical physics cannot. Classical physics can describe many aspects of nature at an ordinary (macroscopic and Microscopic scale, (optical) microscopic) scale, but is not sufficient for describing them at very small submicroscopic (atomic and subatomic) scales. Classical mechanics can be derived from quantum mechanics as an approximation that is valid at ordinary scales. Quantum systems have Bound state, bound states that are Quantization (physics), quantized to Discrete mathematics, discrete values of energy, momentum, angular momentum, and ot ...

Velvet Revolution
The Velvet Revolution () or Gentle Revolution () was a non-violent transition of power in what was then Czechoslovakia, occurring from 17 November to 28 November 1989. Popular demonstrations against the one-party government of the Communist Party of Czechoslovakia included students and older dissidents. The result was the end of Czechoslovak Socialist Republic, 41 years of one-party rule in Czechoslovakia, and the subsequent dismantling of the command economy and conversion to a parliamentary republic. On 17 November 1989 (International Students' Day), riot police suppressed a Student activism, student demonstration in Prague. The event marked the 50th anniversary of a violently suppressed demonstration against the Nazi storming of Prague University in 1939 where 1,200 students were arrested and 9 killed (see International Students' Day#Origin, Origin of International Students' Day). The 1989 event sparked a series of demonstrations from 17 November to late December and turned ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hloubětín
Hloubětín (, ) is a district of Prague located from the centre, belonging mostly to Prague 9, with parts of it also belonging to Prague 14 and Prague 10. There were 10,704 people living in this area in 2001. The area, first recorded in the 13th century due to presence of the Teutonic Knights, became part of Prague in 1922. Today it is mainly an industrial area, located on the edge of Prague's so-called ''průmyslový polookruh'' (industrial semi-circle). During communist times, Hloubětín was well known as the home of the Tesla company. Etymology The name "Hloubětín" derives from the surname ''Hlúpata'', and was previously known as ''Lupatin'', ''Glupetin'', ''Hlupetin'' and ''Hloupětín'' before becoming Hloubětín in 1907. Geography The area lies on the Rokytka river, and its northern reaches back onto the area of Kbely Airport. To the west of Hloubětín lies Hořejší rybník, a protected area centered on a lake.

Czechoslovakia
Czechoslovakia ( ; Czech language, Czech and , ''Česko-Slovensko'') was a landlocked country in Central Europe, created in 1918, when it declared its independence from Austria-Hungary. In 1938, after the Munich Agreement, the Sudetenland became part of Nazi Germany, while the country lost further territories to First Vienna Award, Hungary and Trans-Olza, Poland (the territories of southern Slovakia with a predominantly Hungarian population to Hungary and Zaolzie with a predominantly Polish population to Poland). Between 1939 and 1945, the state ceased to exist, as Slovak state, Slovakia proclaimed its independence and Carpathian Ruthenia became part of Kingdom of Hungary (1920–1946), Hungary, while the German Protectorate of Bohemia and Moravia was proclaimed in the remainder of the Czech Lands. In 1939, after the outbreak of World War II, former Czechoslovak President Edvard Beneš formed Czechoslovak government-in-exile, a government-in-exile and sought recognition from the ...
