(Royal Society of Chemistry (RSC), 2017)We introduce a fully stand-alone version of the Quantum Chemistry Electron Ionization Mass Spectra (QCEIMS) program [S. Grimme, Angew. Chem. Int. Ed., 2013, 52, 6306] allowing efficient simulations for molecules composed of elements with atomic numbers ... -
(2021-09-22)One of the recently established paradigms in condensed matter physics is examining a system’s behaviour in artificial potentials, giving insight into phenomena of quantum fluids in hard-to-reach settings. A prominent example is the matter-wave scatterer ...

(University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2017-12)Nanomagnetic systems and transitions between magnetic states are currently an active topic of research. Spintronics is, in particular, a new branch of science and technology where spin degrees of freedom and spin currents are used in an analogous way ...
-
(American Chemical Society (ACS), 2020-08-05)The nitrogenase enzymes are responsible for all biological nitrogen reduction. How this is accomplished at the atomic level, however, has still not been established. The molybdenum-dependent nitrogenase has been extensively studied and is the most ...

(Elsevier BV, 2019-12)The transport properties of a wire-dot system coupled to a quantized single photon with linear polarization in a 3D-cavity is theoretically studied using a quantum master equation. The system is also coupled to a photon reservoir, environment. We ...

(American Chemical Society (ACS), 2020-02-27)Electron paramagnetic resonance (EPR) spectroscopy, coupled with site-directed spin labeling (SDSL), is a useful method for studying conformational changes of biomolecules in cells. To employ in-cell EPR using nitroxide-based spin labels, the structure ...

(University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2020-09)This thesis discusses two aspects of semi-classical black holes. First, a recently improved semi-classical formula for the entanglement entropy of black hole radiation is examined. This entropy is an indicator of information loss and determines ...

(Springer Science and Business Media LLC, 2020-02-24)Films of SiGe nanocrystals (NCs) in oxide have the advantage of tuning the energy band gap by adjusting SiGe NCs composition and size. In this study, SiGe-SiO2 amorphous films were deposited by magnetron sputtering on Si substrate followed by rapid ...
-
(Springer Science and Business Media LLC, 2020-03-01)Using supersymmetric localization we compute the free energy and BPS Wilson loop vacuum expectation values for planar maximally supersymmetric Yang-Mills theory on Sd in the strong coupling limit for 2 ≤ d < 6. The same calculation can also be performed ...
-
(American Physical Society (APS), 2017-10-10)We show for a simple noncollinear configuration of the atomistic spins (in particular, where one spin is rotated by a finite angle in a ferromagnetic background) that the pairwise energy variation computed in terms of multiple-scattering formalism ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2021-08-30)The physics of light-matter interactions is a rapidly developing research area at the junction between condensed matter physics and quantum optics. Depending on the strength of the light-matter interaction the systems behave very differently. In the ...
-
(Springer Nature, 2018-02-12)We investigate theoretically thermal and electrical conductances for the system consisting of a quantum dot (QD) connected both to a pair of Majorana fermions residing at the edges of a Kitaev wire and two metallic leads. We demonstrate that both ...
-
(Springer Science and Business Media LLC, 2020-06-01)Large classes of AdSpsupergravity backgrounds describing the IR dynamicsofp-branes wrapped on a Riemann surface are determined by a solution to the Liouvilleequation. The regular solutions of this equation lead to the well-known wrapped branesupergravity ...
