Responsive Hydrogels for Label-Free Signal Transduction within Biosensors
(Journal article; Peer reviewed, 2010)Hydrogels have found wide application in biosensors due to their versatile nature. This family of materials is applied in biosensing either to increase the loading capacity compared to two-dimensional surfaces, or to support ... -
The role of the QBO in the inter-hemispheric coupling of summer mesospheric temperatures
(Journal article; Peer reviewed, 2010)Inter-hemispheric coupling between the polar summer mesosphere and planetary-wave activity in the extra-tropical winter stratosphere has recently been inferred using Polar Mesospheric Cloud (PMC) properties as a proxy for ... -
Unconventional Superconductivity on a Topological Insulator
(Journal article; Peer reviewed, 2010)We study proximity-induced superconductivity on the surface of a topological insulator (TI), focusing on unconventional pairing. We find that the excitation spectrum becomes gapless for any spin-triplet pairing, such that ... -
Spin-triplet supercurrent through inhomogeneous ferromagnetic trilayers
(Journal article; Peer reviewed, 2010)Motivated by a recent experiment [J. W. A. Robinson, J. D. S. Witt, and M. G. Blamire, Science 329, 5987 (2010)], we report here the possibility of establishing a long-range spin-triplet supercurrent through an inhomogeneous ... -
Strongly anharmonic current-phase relation in ballistic graphene Josephson junctions
(Journal article; Peer reviewed, 2010)Motivated by a recent experiment directly measuring the current-phase relation (CPR) in graphene under the influence of a superconducting proximity effect, we here study the temperature dependence of the CPR in ballistic ... -
Interactions of High Aspect Ratio Nanostructures and Biological Systems
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:245, Doctoral thesis, 2010)As the length scale of basic biological processes coincides more and more with the length scale at which artificial nanostructures can be constructed, the interplay between those structures and biological systems becomes ... -
Interplay between superconductivity and ferromagnetism on a topological insulator
(Journal article; Peer reviewed, 2010)We study theoretically proximity-induced superconductivity and ferromagnetism on the surface of a topological insulator. In particular, we investigate how the Andreev-bound states are influenced by the interplay between ... -
Triplet proximity effect and odd-frequency pairing in graphene
(Journal article; Peer reviewed, 2010)We study the interplay between proximity-induced superconductivity and ferromagnetism in graphene by self-consistently solving the Bogoliubov de Gennes equations on the honeycomb lattice. We find that a strong triplet ... -
Spin-active interfaces and unconventional pairing in half-metal/superconductor junctions
(Journal article; Peer reviewed, 2010)We study the physical properties of a half-metallic ferromagnet∣superconductor (HM∣S) bilayer, allowing for an arbitrary bulk pairing symmetry of the superconductor and spin-dependent processes at the interface. In particular, ... -
Open Systems and Measurement in Quantum Optics: The Photodetection Process and Master Equations
(Master thesis, 2010)All real quantum systems are open, and in particular in thefield of quantumoptics, the measurement process has always been a fundamental object of study.Naturally, simulating such systems and processes on computers is of ... -
Probing phase separation in Bose-Fermi mixtures by the critical superfluid velocity
(Journal article; Peer reviewed, 2010)We investigate the effect exerted by spin-polarized fermions on the interaction between superfluid bosons for a Bose-Fermi mixture residing on an optical lattice, with particular emphasis on the possibility of an induced ... -
Structure and oscillatory multilayer relaxation of the bismuth (100) surface
(Journal article; Peer reviewed, 2010)We present a combined experimental and theoretical study of the surface structure of single crystal Bi(100) via scanning tunneling microscopy (STM), low-energy electron diffraction intensity versus energy (LEED-IV) analysis ... -
Domain structures in PbTiO3 thin films
(Master thesis, 2010)We have studied thin films (27 and 50 unit cells) of ferroelectric PbTiO3 by acquiring reciprocal space maps using wide-angle x-ray scattering. Diffuse satelites were found around the PbTiO3 Bragg peaks, consistent with a ... -
Scanning tunneling microscopy based point-contact measurements of nanoscale magnetic systems
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:178, Doctoral thesis, 2010)In this thesis, the method of scanning tunneling microscopy (STM) based pointcontacts is presented together with measurements on nanonscale magnetic systems. The method allows point-contacts to be positioned with nm lateral ... -
Planetary Wave Oscillations Observed in Ozone from Troll Station Antartica
(Master thesis, 2010)This thesis investigates the possibility of tracing planetary waves with ozone. The mixing ratio of ozone is sensitive to variations of its environment introduced by waves due to its short chemical lifetime. Ground-based ... -
