Phase diagram of an extended Kane-Mele-Hubbard model in strongly correlated regime
(Master thesis, 2020)Hovedformålet med denne masteroppgaven er å se på en utvidet Kane-Mele-Hubbard-modell i sterkt korrelerende regime fra referansen [Juan M. Losada, 2019], der både anisotropi- og Dzyaloshinskii-Moriya-vekselvirkninger (DMV) ... -
Phase perturbative calculations of diffuse light scattering on randomly rough surfaces in and out of plane
(Master thesis, 2021)Ved en eller annen lendgdeskala viser alle overflater en grad av ruhet, og det er viktig å forstå de fysiske konsekvensene av det. Denne oppgaven handler om refleksjon av elekromagnetiske bølger i det optiske bølgelengderegimet ... -
Phase separation and orientational ordering of synthetic Na-fluorohectorite clay particles in saline aqueous suspensions
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:130, Doctoral thesis, 2008)The main goal of the present thesis is to determine and better understand the phase diagram for the nano-layered synthetic clay sodium fluorohectorite dispersed in saline aqueous solutions. This system displays up to four ... -
Phase stability and electronic structure of iridium metal at the megabar range.
(Journal article; Peer reviewed, 2019)The 5d transition metals have attracted specific interest for high-pressure studies due to their extraordinary stability and intriguing electronic properties. In particular, iridium metal has been proposed to exhibit a ... -
Phase stabilization principle and precipitate-host lattice influences for Al-Mg-Si-Cu alloy precipitates
(Journal article, 2014)In this work, we seek to elucidate a common stabilization principle for the metastable and equilibrium phases of the Al–Mg–Si–Cu alloy system, through combined experimental and theoretical studies. We examine the structurally ... -
Phase structure and critical properties of an abelian gauge theory
(Dr. ingeniøravhandling, 0809-103X; 2001:116, Doctoral thesis, 2002)Chapter 1 to 4 give a short introduction to superconductivity, microscopic theory, phase transitions, and Monte-Carlo simulations. Chapter 2 is about Cooper pairing in different settings, but I also give a short introduction ... -
Phase transitions and correlations in fracture processes where disorder and stress compete
(Peer reviewed; Journal article, 2020)We study the effect of the competition between disorder and stress enhancement in fracture processes using the local load sharing fiber bundle model, a model that hovers on the border between analytical tractability and ... -
Phase transitions in effective lattice models for strongly correlated systems
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:174, Doctoral thesis, 2006)In three research articles we have studied the critical properties of effective lattice models for strongly correlated electron systems by Monte Carlo simulations. A similar model is used in a fourth article for investigating ... -
Phase transitions in low dimensional systems via spontaneous symmetry breaking and topology
(Doctoral thesis at NTNU;2015:271, Doctoral thesis, 2015)In nature there exists a fundamental distinction among particles regarding their statistics. Let us consider an isolated systems of two particles: two bosons are allowed to stay in the same physical state while two fermions ... -
