  1. 1. Quantum Hall Wave Functions on the Torus

    Författare :Mikael Fremling; Hans Hansson; Nicolas Regnault; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fractional Quantum Hall Effect; teoretisk fysik; Theoretical Physics;

    Sammanfattning : The fractional quantum Hall effect (FQHE), now entering it's fourth decade, continues to draw attention from the condensed matter community. New experiments in recent years are raising hopes that it will be possible to observe quasi-particles with non-abelian anyonic statistics. These particles could form the building blocks of a quantum computer. LÄS MER

  3. 2. Magnetoresistance and Space : Micro- and Nanofeature Sensors Designed, Manufactured and Evaluated for Space Magnetic Field Investigations

    Författare :Anders Persson; Hugo Nguyen; Greger Thornell; Johan Åkerman; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tunneling Magnetoresistance; Planar Hall effect; Magnetic tunnel junction; Magnetometer; Materials science; Teknisk materialvetenskap; Engineering physics; Teknisk fysik; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Sammanfattning : In recent years, the interest for miniaturization of spaceborne instruments and subsystems has increased steadily, as this enables development of small and lightweight satellite classes as well as more versatile payloads on traditional spacecraft. In essence, this thesis work is an investigation of the applicability of magnetoresistive technology to a magnetometer intended for space. LÄS MER

  4. 3. Study of novel electronic materials by mid-infrared and terahertz optical Hall effect

    Författare :Nerijus Armakavicius; Vanya Darakchieva; Philipp Kühne; Mircea Modreanu; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Development of silicon based electronics have revolutionized our every day life during the last three decades. Nowadays Si based devices operate close to their theoretical limits that is becoming a bottleneck for further progress. LÄS MER

  5. 4. Coherent State Wave Functions on the Torus

    Författare :Mikael Fremling; Hans Hansson; Jon Magne Leinaas; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum Hall Effect; fysik; Physics;

    Sammanfattning : In the study of the quantum Hall effect there are still many unresolved problems. One of these is how to generate representative wave functions for ground states on other geometries than the planar and spherical. We study one such geometry, the toroidal one, where the periodic boundary conditions must be properly taken into account. LÄS MER

  7. 5. Free charge carrier properties in group III nitrides and graphene studied by THz-to-MIR ellipsometry and optical Hall effect
