  2. 1. Triptych of quantum matter in one dimension : Playful constructions in theoretical and computational physics

    Author : Axel Gagge; Jonas Larson; Andrew Daley; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bloch oscillations; Peierls; adiabatic; diabatic; ultracold atoms; Bose-Fermi mixtures; phonon; cQED; superradiance; polarons; DMRG; MPS; Kosterlitz-Thouless; Wannier; Bloch; quantum phase transitions; Theoretical Physics; teoretisk fysik;

    Abstract : In this compilation thesis, three different quantum mechanical systems are presented. All three have in common that they are one-dimensional quantum systems which, each in their own way, can be seen as analogous to other quantum systems. READ MORE

  4. 2. Intermediate heat exchange in binary distillation

    Author : Ingela Niklasson Björn; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intermediate heat exchange; Efficiency.; Diabatic distillation;

    Abstract : AbstractThe overall reason for investigating intermediate heat exchange in diabatic distillation is to enable a reduction in external energy demand.This thesis applies computer simulations and experimental measurements to evaluate and analyse the use of intermediate heat exchange in binary distillation.

  6. 4. Quantum Wavepacket Dynamics in Molecular and Trapped Ion Systems

    Author : Dong Wang; Tony Hansson; Volker Engel; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; wavepacket; revival; anisotropy; polarization; Molecular physics; Molekylfysik; kemisk fysik; Chemical Physics;

    Abstract : The motions of a wavepacket in the two coupled potentials studied in this thesis can be classified into either bistable or astable motion according to the wavepacket interference at the curve crossing. Bistable motion, in which the wavepacket performs a coupled oscillation but remains in the same adiabatic and diabatic state, can exist both in bound-bound systems and bound-unbound ones with long time stability.

  7. 5. Measurements of Film Flow Rate in Heated Tubes with Various Axial Power Distributions

    Author : Carl Adamsson; Henryk Anglart; Bengt Sundén; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; film flow; film thickness; dryout; power distribution; annular flow; Atomic physics; Atomfysik;

    Abstract : Measurements of film mass flow rate for annular, diabatic steam-water flow in tubes are presented. The measurements were carried out with four axial power distributions and at several axial positions at conditions typical for boiling water reactors, i.e. 7 MPa pressure and total mass flux in a range from 750 to 1750 kg/m2s.
