Scattering theory of the bifurcation in quantum measurement
Karl-Erik Eriksson, Kristian Lindgren
We model quantum measurement of a two-level system . Previous obstacles for understanding the measurement process are removed by basing the analysis of the interaction between $…
An interview based study of pioneering experiences in teaching and learning Complex Systems in Higher Education
Joseph T. Lizier, Michael S. Harré, Melanie Mitchell +5
Due to the interdisciplinary nature of complex systems as a field, students studying complex systems at University level have diverse disciplinary backgrounds. This brings challeng…
Bifurcation in Quantum Measurement
Karl-Erik Eriksson, Martin Cederwall, Kristian Lindgren +1
We present a generic model of (non-destructive) quantum measurement. Being formulated within reversible quantum mechanics, the model illustrates a mechanism of a measurement proces…
The approach towards equilibrium in a reversible Ising dynamics model -- an information-theoretic analysis based on an exact solution
Kristian Lindgren, Eckehard Olbrich
We study the approach towards equilibrium in a dynamic Ising model, the Q2R cellular automaton, with microscopic reversibility and conserved energy for an infinite one-dimensional…
Expressing the entropy of lattice systems as sums of conditional entropies
Torbjørn Helvik, Kristian Lindgren
Whether a system is to be considered complex or not depends on how one searches for correlations. We propose a general scheme for calculation of entropies in lattice systems that h…
Evolutionary Exploration of the Finitely Repeated Prisoners' Dilemma--The Effect of Out-of-Equilibrium Play
Kristian Lindgren, Vilhelm Verendel
The finitely repeated Prisoners' Dilemma is a good illustration of the discrepancy between the strategic behaviour suggested by a game-theoretic analysis and the behaviour often ob…
