  1. 1. Analyses and Application of Ambient Seismic Noise in Sweden Source, Interferometry, Tomography

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Hamzeh Sadeghisorkhani; Uppsala universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Seismic interferometry; Ambient noise; Surface wave; Wave propagation; Inverse theory; Sweden; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    Abstract : Ambient seismic noise from generation to its application for determination of sub-surface velocity structures is analyzed using continuous data recordings from the Swedish National Seismic Network (SNSN). The fundamental aim of the thesis is to investigate the applicability of precise velocity measurements from ambient noise data. READ MORE

    Abstract : Popular Abstract in Swedish Egenskaperna hos de material som utgör och omger oss, som t.ex. färg, struktur och kemiska egenskaper, bestäms av hur elektronerna som är en del av dess byggstenar, atomerna, är strukturerade. Ett sätt att undersöka elektronstrukturen är med hjälp den fotoelektriska effekten. READ MORE

    Abstract : This thesis is the result of three years of work in Lund University, as a member of DELPHI group, at the Elementary Particle Physics Department. The work concerns the study of Bose-Einstein correlations in electron-positron collisions at LEP. READ MORE

  4. 4. Majorana Representation in Quantum Optics SU(2) Interferometry and Uncertainty Relations

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Saroosh Shabbir; KTH.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Majorana representation; Quantum optics; interferometry; SU 2 group; angular momentum; arbitrary optical gates; Physics; Fysik;

    Abstract : The algebra of SU(2) is ubiquitous in physics, applicable both to the atomic spin states and the polarisation states of light. The method developed by Majorana and Schwinger to represent pure, symmetric spin-states of arbitrary value as a product of spin-1/2 states is a powerful tool that allows for a great conceptual and practical simplification.

  5. 5. Three Pion Interferometry in the NA44 Experiment

    University dissertation from Lund University, EPF, Box 118, 221 00 Lund

    Author : Janus Schmidt-Sörensen; Lunds universitet.; Lund University.; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum field theory; heavy-ion physics; bose-einstein; Elementary particle physics; interferometry; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:1999:Schmidt-Sörensen;

    Abstract : This thesis presents a three-particle correlation analysis with pions originating from Sulphur-Lead and Lead-Lead collisions at 200 and 158 GeV/c per nucleon respectively, taken by the CERN heavy-ion experiment NA44. The genuine three-body correlation is suppressed in both colliding systems which indicates that the particle production source is partly coherent. READ MORE
