  2. 1. Momentum exchange between light and nanostructured matter

    Author : Daniel Andrén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase-gradient metasurface; optical force and torque; metavehicle; momentum exchange.; nano-optics; rotary nanomotor; optical tweezers;

    Abstract : An object's translational and rotational motion is associated with linear and angular momenta. When multiple objects interact the exchange of momentum dictates the new system's motion. READ MORE

  4. 2. Optical metasurfaces for momentum exchange between light and matter

    Author : Mohammad Mahdi Shanei; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; optical forces and torques; phase-gradient metasurface; particle transport; optical momentum exchange; Flat optics; rotary meta-motor; meta-particle;

    Abstract : Light carries energy and momentum that can be transferred to matter. Because of the conservation of total momentum, a change in light momentum due to interaction with an object must be compensated by an equal but opposite change in the momentum of that object. READ MORE

  5. 3. Quantum Kinetic Theory for Plasmas : spin, exchange, and particle dispersive effects

    Author : Robin Ekman; Gert Brodin; Jens Zamanian; Bengt Eliasson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Abstract : This thesis is about developing and studying quantum mechanical models of plasmas. Quantum effects can be important at high densities, at low temperatures, and in strong electromagnetic fields, in various laboratory and astrophysical systems. READ MORE

  6. 4. Nanospintronics with Molecular Magnets - Tunneling and Spin-Electric Coupling

    Author : Javier Francisco Nossa Márquez; Fasta tillståndets fysik; []
    Keywords : Molecular magnets; spin exchange; spin-orbit interaction; magnetic anisotropy; spin frustration; spin chirality; spin-electric control; quantum transport; Coulomb blockade; density functional theory; quantum master equation.;

    Abstract : This dissertation investigates theoretically electric control of the magnetic properties of molecular magnets. Two classes of magnetic molecules are considered. The first class consists of molecules that are spin frustrated. READ MORE

  7. 5. High-resolution measurement of the ¹⁶O(γ,pn) reaction

    Author : Lennart Isaksson; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pn ; E_gamma = 67-76 MeV; resolved states; cross-sections; Nuclear physics; Kärnfysik; Fysicumarkivet A:1996:Isaksson; 16O gamma; Photonuclear reaction;

    Abstract : The 16O(gamma,pn) reaction has been measured with a resolution high enough to resolve individual low-lying states in the residual 14N nucleus. The relative population of the states provides detailed information about the quantum numbers of the proton-neutron pairs on which photons are absorbed. READ MORE
