    Encoding data with magnetic states is currently used in various devices for data transmission, storage, and processing. The operating principle in these devices is often based on controlled switching, e.g., using a pulse of an external magnetic field, ...
  • Angel Ramelli, Juan Fernando (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2020-11)
    In recent years, the study of entanglement properties of quantum field theories has led to deep insights in fields as diverse as quantum gravity and condensed matter physics. Originating as effective field theories for certain quantum dimer models, the ...
  • Mökkönen, Harri (Aalto University, Helsinki;University of Iceland, Reykjavik, 2016)
    A polymer escaping from a confining external potential represents a generic description of long macromolecules crossing an energy barrier. This type of barrier crossing problems are typical in nano- and microscale polymeric systems, where the polymers ...
  • Elm Heintz, Kasper (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2019-07)
    In the early Universe, most of the cold neutral gas that will later form into individual stars and galaxies is practically invisible to us. These neutral gas reservoirs can, however, be illuminated by bright cosmic lightsources such as gamma-ray bursts ...
  • Kateb, Movaffaq (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2019-12-12)
    Permalloy Ni80Fe20 at. % (Py) is a well-known ferromagnet utilized in anisotropic magnetoresistance and planar Hall effect sensors as well as magnetic read heads in magnetic memories. These applications rely on the uniaxial magnetic anisotropy in ...
  • Hjörleifsson, Jens G (Jens Guðmundur Hjörleifsson, 2018-06-06)
    Protein quaternary structures are fundament for life. Proteins have evolved towards large assemblies of subunits needed for the execution of complex chemistry, for building structural components or for compartmentalization. Most oligomeric enzymes ...
  • Frater, Paul (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2020-06)
    Age and length (i.e. composition) data are, along with abundance indices, some of the most basic yet informative data collected in fisheries science. Measurements on age and length have been collected since the study of fish and fish stocks began in ...
  • Óskarsson, Kristinn Ragnar (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2020-10)
    Life on earth is found everywhere where water is found, meaning that life has adapted to extremely varied environments. Thus, protein structures must adapt to a myriad of environmental stressors while maintaining their functional forms. In the case ...
  • Kamali, Ali (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2023-06-29)
    The focused electron beam-induced deposition (FEBID) process, a 3D nanofabrication technique, involves the utilization of a concentrated electron beam of high energy to dissociate precursor molecules that are adsorbed on a substrate, resulting in the ...
  • Cipriani, Maicol (2022-06-16)
    The interaction of low-energy electrons (LEEs) with neutral molecules plays an important role in various applications. In focused electron beam induced deposition (FEBID), a direct-write 3D nanofabrication technique, a high-energy focused electron beam ...
  • Thorman, Rachel Megan (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2017-10-27)
    Focused electron beam induced deposition (FEBID) is a nanofabrication technique wherein electron-induced reactions are used to deposit pure metals from organometallic precursors under the area of a primary electron beam. It can be used to directly ...
  • T P, Ragesh Kumar (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2017-12-15)
    Focused electron beam induced deposition (FEBID) is a direct-write 3D nanofabrication technique, which works on the principle of electron-induced molecular decomposition. In FEBID, a high-energy focused electron beam dissociates the precursor molecules ...
  • Björnsson, Hjörtur (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2023-05)
    In this thesis we explore Lyapunov functions for stochastic differential equations. Lyapunov functions are a useful tool to study the stability of an equilibrium of such stochastic systems and long term behaviour of solutions around an equilibrium ...
  • Juhl, Michael (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2018-10)
    The polarization of electromagnetic waves (the direction of transversal vibration of its electric field vector) provides essential information about the emitting sources and scattering objects. Its measurement, i.e., optical polarimetry, has a history ...
  • Hafliðason, Arnar (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2018-12)
    The research focused on multiphoton dynamics and fragment formation for HBr, DCl, and bromomethanes, using mass resolved multiphoton ionization (MR-MPI) and velocity map imaging (VMI) techniques. Data interpretations were based on analysis of (2+n)REMPI ...
