    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Seismic interferometry; Ambient noise; Surface wave; Wave propagation; Inverse theory; Sweden; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    Sammanfattning : 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. LÄS MER

  2. 2. Attosecond interferometry: techniques and spectroscopy

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :David Kroon; Lund University.; Lunds universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2016:Kroon; Electron wave packet; Attosecond Pulse trains; Photoionization; Photoemission time delay; High-order harmonic generation; Interferometry; Electron dynamics;

    Sammanfattning : The interaction between an intense laser pulse and a gas medium leads to the emission of coherent bursts of light in the extreme ultraviolet range. This process, known as high-order harmonic generation, has today, almost three decades after its discovery, developed into a reliable source of extremely short (on the order of 100 as) pulses of electromagnetic radiation, with a wide range of applications in the atomic, molecular and optical sciences.

    Sammanfattning : 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. LÄS MER

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

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

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

    Sammanfattning : 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

    Detta är en avhandling från Lund University, EPF, Box 118, 221 00 Lund

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

    Sammanfattning : 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. LÄS MER
