About Me

I work partly as a Post-Doc at the Institute of theoretical physics at Utrecht University, the Netherlands, and partly as project manager for the new research consortium QuMat .

In 2015-2018 I was a Post-Doc at the Department of Theoretical Physics at Maynooth University, Ireland.

I did my PhD at the Theory of Quantum Matter group (TQM) at Fysikum, Stockholm University, Sweden.


The main focus of my research is on Fractional Quantum Hall Effect.
I use exact diagoalization, Monte Carlo and methods and techniques from conformal field theory to study the higly correlated state that constitutes the quantum Hall liquid.

My publications can be found here.
arXiv preprints and Google Scolar links are here and here.

Corona Cannonball

all deaths in the world

In these trying times of Corona I find myself spending quite some time looking a statistics over deaths and cases. In this link I keep my own diagram over the development in the world.

I hope you find them as useful as I have.


I have extensive teaching experience from Stockholm, Maynooth, and Utrecht, covering both lecturing and teaching assistance.
At the moment, I do not have any teaching responsibilities, but here I keep a complete list of my teaching experiences.


Research can also be beautiful.

Such as these videos of many-particle wave functions as part of Phys. Rev. B 98 235139


As part of the the research on fractional quantum Hall system, I have contributed to the development of an open source package named Hammer.


In May 2015 I defended my doctoral thesis Quantum Hall Wave Functions on the Torus.
My two supervisors were Hans Hansson and Anders Karlhede.
Nothing is without typos, so here is an associated erratum.

In May 2013 I defended my licentaite thesis Coherent State Wave Functions on the Torus.

In September 2008 I defended my master thesis Dark Halos in The Milky Way.

Research Videos

My controbution to JuliaCon 2022, discussing MathLink.

This presentation was supposed to have been given at the 2020 APS march meeting, which got canceled do the the corona virus.


In October 2017 I delivered an (award winning) 5 minute presentation at the Maynooth University research week.

In october 2015 gave an inspirational lecture on as part of the Lise Meitner days hosted by Stockholm University and the Royal Institute of Technology.

In October 2015 I gave a short lecture on my research as part of the researcher day at Stockholm University.

In December 2013 I was invited to the Nobel museum to give a lecture when they comemorated the centenial of the Bohr model.

During the Summer of 2013 i recorded an episode for Kvacksnack Sommar 2013 where I talked about my life as a PhD student, alleged pyramids in Bosnia and the board game Go.

In February 2013 I was invited to give a lecture at the Pop Science Pub, organized by Vetenskap och folkbildning, to talk about "Kvantmekanik för dummies".

In December 2012 I participated in the radio show Institutet where I talked about tunneling.


When writing reports och hand-in-exercices it is generally nicest to do this in LaTex.
Having said that, many people find latex cumbersome or hostile (I don't blame them). My suggestion is to start with a visual latex editor instead.
The one I'm thinking of is called LyX and is avaliable for Windows, Mac and of course Linux (write "apt-get install lyx" on command line).

When writing in LyX/LaTex there are some special notations one would often like to use. I therefore have a file containing examples of different macros that can come quite in handy.
(The collection of macros does contain some special packages so you might not be able to make a pdf/dvi on a vanilla instalation of LyX).
