Magnus Paulsson

Magnus Paulsson is an Assistant Professor in the Department of Physics and Electrical Engineering at Linnaeus University, affiliated with the Faculty of Technology. He is a prominent member of the Condensed Matter Physics (CMP) research group, where he conducts theoretical studies of electron transport in nanoscale systems. Based in Kalmar but frequently teaching in Växjö, he instructs courses in Mechanics, Computer Physics I & II, and Density Functional Theory (DFT).

Dr. Paulsson earned his doctorate in 2001 with a thesis titled "Electron transport in pi-conjugated systems," establishing the foundation for his research career in nanoscale electron transport phenomena. His academic journey has focused on the theoretical aspects of molecular electronics and quantum transport, developing computational methods to understand electron behavior at the molecular level.

His research primarily centers on the theoretical description of electron transport in nano-scale junctions, with particular emphasis on molecular electronics, scanning tunneling microscopy (STM), and inelastic electron tunneling spectroscopy. Paulsson's work bridges computational physics and experimental nanotechnology, advancing our understanding of how molecular vibrations affect electron transport and how single-molecule junctions can be controlled and manipulated. His contributions have significantly impacted the field of molecular electronics, particularly in developing first-principles methods to simulate and predict nanoscale transport phenomena.

Analysis of Paulsson's publication record reveals a consistent focus on the intersection of quantum mechanics, surface science, and nanoelectronics. His work systematically applies density functional theory (DFT) and non-equilibrium Green's function (NEGF) methods to study molecular-scale electron transport. A notable trend throughout his career is his investigation of how molecular vibrations influence electron tunneling processes, which has important implications for the development of molecular-scale electronic devices. His research spans fundamental quantum phenomena to potential applications in molecular switches, sensors, and future electronic technologies.
