• #### Forward and midrapidity like-particle ratios from p+p collisions at root s=200 GeV ﻿

(Elsevier, 2005-02)
We present a measurement of π−/π+π−/π+, K−/K+K−/K+ and p¯/p from p+pp+p collisions at s=200 GeV over the rapidity range 0<y<3.40<y<3.4. For pT<2.0 GeV/cpT<2.0 GeV/c we see no significant transverse momentum dependence ...

• #### Forward-backward multiplicity correlations in pp collisions at √s = 0.9, 2.76 and 7 TeV ﻿

(Springer, 2015-05-20)
The strength of forward-backward (FB) multiplicity correlations is measured by the ALICE detector in proton-proton (pp) collisions at s√ = 0.9, 2.76 and 7 TeV. The measurement is performed in the central pseudorapidity ...

• #### Forward-central two-particle correlations in p-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV ﻿

(Elsevier, 2016-02)
Two-particle angular correlations between trigger particles in the forward pseudorapidity range ($2.5 < |\eta| < 4.0$) and associated particles in the central range ($|\eta| < 1.0$) are measured with the ALICE detector in ...

• #### Free-standing, axially-symmetric diffraction gratings for neutral matter-waves: experiments and fabrication ﻿

(The University of Bergen, 2011-10-04)
Since de Broglie’s famous postulation of the wave-nature of material particles and its subsequent experimental verification, it is known that atoms and molecules behave like waves on a small scale. The investigation of ...

• #### Freeze-Out in the Multi-Module Model of Ultra-Relativistic Heavy Ion Collisions ﻿

(The University of Bergen, 2003)
Master thesis
• #### Freeze-out radii extracted from three-pion cumulants in pp, p-Pb and Pb-Pb collisions at the LHC ﻿

(Elsevier, 2014-12-12)
In high-energy collisions, the spatio-temporal size of the particle production region can be measured using the Bose–Einstein correlations of identical bosons at low relative momentum. The source radii are typically extracted ...
Journal article
• #### Fundamental aspects of water methane separation in zeolites ﻿

(The University of Bergen, 2013-06-03)
The main objective of this thesis was to use molecular dynamics to investigate the methane interactions with zeolite, specifically the Linde Type A-3A, alongside with an investigation into the use of polynomial path ...

Doctoral thesis
• #### Geo-modeling and fluid flow simulation in paleokarst reservoirs ﻿

(The University of Bergen, 2015-06-30)
This master thesis focuses on modeling and simulation of fluid flow in collapsed paleocave systems, also known as paleokarst. Petroleum reservoirs all around the world exhibit karst structures. The latest ones on the ...

• #### A giant reconstruction of α-quartz (0001) interpreted as three domains of nano dauphine twins ﻿

(Europe PMC, 2015-10-08)
Silica (SiO2) is one of the most common materials on Earth. The crystalline form α-quartz is the stable silica polymorph at ambient conditions although metastable forms exist. α-quartz is a piezoelectric material, it can ...
Journal article
• #### The global potential for carbon capture and storage from forestry ﻿

(Springer, 2016-02-26)
Background: Discussions about limiting anthropogenic emissions of CO2 often focus on transition to renewable energy sources and on carbon capture and storage (CCS) of CO2. The potential contributions from forests, forest ...

• #### Global Λ polarization in high energy collisions ﻿

(American Physical Society, 2017-03-14)
With a Yang-Mills flux-tube initial state and a high-resolution (3+1)D particle-in-cell relativistic (PICR) hydrodynamics simulation, we calculate the Λ polarization for different energies. The origination of polarization ...
Journal article
• #### A Golden-Channel Higgs Decay ﻿

(The University of Bergen, 2011-06-01)
With a Higgs mass greater than 190 GeV and lower than 300 GeV, the decay channel H --> ZZ --> 4l becomes what is referred to as the golden channel for Higgs decay (clean signal). Suppose a pair of on shell Zs with ...

• #### GPS scintillation and irregularities at the front of an ionization tongue in the nightside polar ionosphere ﻿

(WileyAmerican Geophysical Union, 2014-10)
In this paper we study a tongue of ionization (TOI) on 31 October 2011 which stretched across the polar cap from the Canadian dayside sector to Svalbard in the nightside ionosphere. The TOI front arrived over Svalbard ...
Journal article
• #### GPS scintillations associated with cusp dynamics and polar cap patches ﻿

(EDP Sciences, 2017)
This paper investigates the relative scintillation level associated with cusp dynamics (including precipitation, flow shears, etc.) with and without the formation of polar cap patches around the cusp inflow region by the ...

• #### Gravitino dark matter and the flavour structure of R-violating operators ﻿

(Elsevier, 2009-06-15)
We study gravitino dark matter and slow gravitino decays within the framework of R-violating supersymmetry, with particular emphasis on the flavour dependence of the branching ratios and the allowed R-violating couplings. ...
