  2. 21. Cryogenic InP High Electron Mobility Transistors in a Magnetic Field

    Author : Isabel Harrysson Rodrigues; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; magnetic field; cryogenic; low noise amplifier; angular dependence; InP HEMT; geometrical magnetoresistance;

    Abstract : The InGaAs-InAlAs-InP high electron mobility transistor (InP HEMT) is the preferred active device used in a cryogenic low noise amplifier (LNA) for sensitive detection of microwave signals. In this thesis it is demonstrated that the InP HEMT, when placed in a magnetic field, has a strong angular dependence in its output current. READ MORE

  5. 23. Athletic Sprint Start Biomechanics : Investigations into the relationships between three dimensional starting technique, first step width and performance

    Author : Paul Nicolas Sandamas; Anton Arndt; Elena M. Gutierrez-Farewik; Aki Salo; Gymnastik- och idrottshögskolan; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sprint start; step width; biomechanics; performance; angular momentum; Medicin Teknik; Medicine Technology;

    Abstract : The block and early acceleration phase plays a very important role in the overall outcome of athletic sprint events. During this part of the race it is commonly observed that sprinters use a lower-body technique that involves the swing leg crossing medially in front of the athlete followed by wide steps. READ MORE

  6. 24. Majorana Representation in Quantum Optics : SU(2) Interferometry and Uncertainty Relations

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

    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.
