(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Newly observed decay schemes of the nuclei 137Sb and 138Sb are reported. The neutron-rich Sb isotopes were produced by the in-flight fragmentation of a 238U primary beam with an energy of 345 MeV/nucleon. Several new excited ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Stability of the vortex matter—magnetic flux lines penetrating into the material—in type-II superconductor films is crucially important for their application. If some vortices get detached from pinning centres, the energy ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Fluid-induced alteration of rocks and mineral-based materials often starts at confined mineral interfaces where nm-thick water films can persist even at high overburden pressures and at low vapor pressures. These films ...
-
(Master thesis / Masteroppgave, 2012)Frost damage in trees is caused when bubbles released from thawing ice cavitate due to the low, and often negative, pressure in trees. This thesis presents the development of a method for in situ observations of such ...
-
(Master thesis / Masteroppgave, 2022)I søket etter ny fysikk videre etter standard modellen brukes det mye tid på å regne ut det samme tverrsnittet flere ganger. Spesielt for kollisjoner som involverer protoner så er parton distribusjon funksjonene veldig ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)The role of spatial resolution of the electron gyroradius in electrostatic particle-in-cell (PIC) simulations is studied. It is demonstrated that resolving the gyroradius is crucial for simulations of strongly magnetized ...

(Doctoral thesis / Doktoravhandling, 2024)This thesis explores Microbially Induced Calcium Carbonate Precipitation (MICP) as a technique for soil improvement with minimal carbon footprint. In this technique, bacteria are used to drive crystallization of calcite ...
-
(Master thesis / Masteroppgave, 2016)In this thesis we conduct numerical studies on plasma-spacecraft interactions by examining two different shapes of spacecrafts, a rocket and a satellite. They are simulated by a cylinder and a box corresponding to the ...

-
(Master thesis / Masteroppgave, 2009)In this thesis, a numerical study of double layers in plasma is presented. Double layers are structures consisting of two oppositely charged space charge layers, creating a finite change in electrostatic potential over the ...
-
(Master thesis / Masteroppgave, 2016)We have done computer simulations on the electrodynamics of rectangular supercon- ducting films. The critical sheet current is an isotropic quantity. By reducing the critical sheet current in a stripe pattern, we have ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)We propose to use lasers to excite magnetic Bloch oscillations in one-dimensional easy-axis ferromagnets at low temperatures. This proposal is investigated numerically in detail for material parameters relevant for ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)We investigate the numerical stability of time-dependent coupled-cluster theory for many-electron dynamics in intense laser pulses, comparing two coupled-cluster formulations with full configuration interaction theory. Our ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)With reference to laboratory Q-machine studies we analyze the dynamics of a plasma diode under external forcing. Assuming a strong axial magnetic field, the problem is analyzed in one spatial dimension by a particle-in-cell ...
-
(Doctoral thesis / Doktoravhandling, 2024)Did you know that in the vacuum of space, there is no vacuum? In fact, most of space is filled with charged particles in a plasma state. Close to Earth, Geomagnetic phenomena, space weather, and radio interference such as ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)We present a numerical study disclosing non-linear effects and hysteresis loops for a swept bias Langmuir probe. A full kinetic particle in cell (PIC) model has been used to study the temporal sheath effects and the probe ...
-
(Master thesis / Masteroppgave, 2013)Packing of equally sized spheres is an extensive field of research, and the applications range from granular media on the macroscopic scale, to theories of liquids and gases. This thesis presents results from numerical ...
-
(Master thesis / Masteroppgave, 2009)In this project I address the questions of how the frictional force depend on the sliding velocity. Can asperity creep give a velocity weakening effect on the dynamic coefficient of friction for low sliding velocities, and ...
