Heinrich Hora (born 1931 in Bodenbach, Czechoslovakia) is a German-Australian theoretical physicist who made contributions to solid state physics, optical properties of plasma with relativistic and quantum effects and nonlinear dynamics with applications of lasers for producing nuclear fusion energy. He lives in Sydney where he is Emeritus Professor at University of New South Wales and Vice-President of the Royal Society of New South Wales. == Academic Career and Achievements == As Foundation Professor of Theoretical Physics at the University of New South Wales from 1975 and emeritus from 1992 he established the Department of Theoretical Physics where a number of students received the university medal, with a record level of publications and where he supervised most of his 25 PhD students. Guest and adjunct professorships include the Rensselaer Polytechnic Institute, the universities of Rochester, Bern, Iowa, Giessen, Tokyo, Regensburg, Osaka, Western Sydney and the Weizmann Institute. For seven years he was active in industrial research at Zeiss, IBM, Westinghouse and Siemens. He also was involved with research for 12 years at the Max-Planck-Institute for Plasma Physics in Garching near Munich, Germany and for one year as Attache remun. at CERN in Geneva, Switzerland. He consulted Rainer Erler to the laser movie "Der Verräter" in the TV series "Das Blaue Palais". His taped lecture course at CERN (1991) about laser acceleration of particles contributed to Gerard Mourou's PeV particle acceleration. His discoveries include the volume mechanism for photo-electric emission, sub-threshold defect generation by electron beams for producing semiconductor junctions with application in solar cells. Prof. Hora's first publication about growth of diamond crystals by physical vapour deposition became an IBM patent in 1964. His first general formula for nuclear energy gain at laser compression and thermal ignition of fusion led to his subsequent discovery of volume ignition (later confirmed by John A. Wheeler as "Wheeler modes"). Against established knowledge he discovered electron acceleration in vacuum by lasers based on nonlinearity.〔H. Hora, Nature 333 (1988) 337〕 His derivation of the nonlinear (ponderomotive) forces of laser-plasma interaction including dielectric effects in the Maxwellian stress tensor led to the prediction of ultrahigh acceleration of plasma blocks〔H. Hora Physics of Laser Driven Plasmas Wiley New York (1981) p. 179〕 being confirmed experimentally by Sauerbrey〔R. Sauerbrey, Physics of Plasmas 3 (1996) 4712〕 with application to a new laser fusion energy scheme as block ignition of uncompressed fuel〔H. Hora, J. Badziak et al.Physics of Plasmas 14 (2007) 072701〕 resulting in a possible nuclear energy production with less radioactivity than burning coal.〔H. Hora, G.H.. Miley et al. Energy and Environmental Science 3 (2010) 479〕〔H. Hora Climatic Problems and Solutions (in German), S. Roderer, Regensburg 2010〕 He discovered the general mechanism of ponderomotive and relativistic self-focusing. His theory for crossing electron and laser beams within media (Schwarz-Hora effect)〔H. Hora Laser and Particle Beams, R.A. Mayers ed. Encyclopedia of Physical Sciences and Technology, Academic Press, San Diego, Vol. 7, 99–128 (1987); Vol. 8, 433–465 (1992)〕〔H. Hora, P.H. Handel Kapitza-Dirac effect with lasers and non-resonant interaction for quantum modulation of electron beams (Schwarz-Hora effect) Applied Physics Letters 102 (2013) 141119〕 led to the discovery of the correspondence principle of electromagnetic interaction and following Nathan Rosen to nonlocality and quantum entangling. Based on the importance of including usually neglected very tiny quantities as the longitudinal field components of laser beams led to the formulation of the nonlinearity principle showing how nonlinear physics is changing from wrong linear physics into correct understanding.〔R. Feynman in H. Hora Climatic Problems and Solutions (in German), S. Roderer, Regensburg 2010 p. 147〕〔H. Hora, Laser Plasma Physics – Forces and the Nonlinearity Principle SPIE PRESS 2000, Bellingham, WA,〕 Hora initiated advanced schemes of laser driven fusion energy and became Director of the foundation of SAFE (Society to Advance Fusion Energy) with the President Luella LaMeer Slaner from the traditional billionaires North of Manhattan and George H. Miley as Executive Director, to push through a law for spending $20 Billions for nuclear fusion research finally signed by President Jimmy Carter in 1980.〔WEEKLY COMPILATION OF PRESIDENTIAL DOCUMENTS, Vol. 16, No. 14, Oct. 7 1980, Public Law 96-386Oct. 7, 1980〕 This led finally to the scheme of laser pulses of 30 kilojoule energy to produce Gigajoule energy from the clean reaction of uncompressed proton-boron fuel 〔Laser and Particle Beams 32 (2014) 409 〕 resulting in less radioactivity than burning coal. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Heinrich Hora」の詳細全文を読む スポンサード リンク
