Da kvantefysikken vokste fram for drøyt hundre år siden, utgjorde den et paradigmeskifte i vår forståelse av naturen, og spesielt av naturens minste bestanddeler. Den har i lang tid fascinert folk også langt utenfor fysikernes rekker og nærmest vært litt myteomspunnen. Etter hvert har kvantefysikken også fått uvurderlig betydning for den teknologiske utviklingen. Kvanteteknologi, med uante...
Five Nobel prizes have highlighted advances in understanding the fundamental physics of how some materials – superconductors – can transport currents without heat loss. Despite this, there is still so much we don’t understand about how these materials interact with other states of matter, or external impulses. Here we’ll explore some of these fundamentals, and how certain interactions can let...
We are in the middle of what has been called the second quantum revolution, where precise control over systems that obey the laws of quantum physics enable progress in many technologies, e.g., computers, sensors, and communication devices. In this presentation, I will explain what quantum technology is based on and what it can be used for. I will also give an overview of the Swedish efforts in...
I want to take you on a journey through the last ten years of my field of research - 4D live microscopy. Live microscopy allows us to observe living cells in real-time and capture dynamic processes as they unfold and evolve in 3D space. This capability provides invaluable insights into the complex and dynamic nature of biological systems, as well as stunning imagery. I’ll be focusing on...
In our daily life, gravity is always an attractive force. After Hubble discovered the expansion of the Universe in 1929, it has been usual to think that the expansion of the Universe must be decelerating, although there have also been other ideas. In fact, Einstein first in 1917 inserted the “cosmological constant” in his equations, as a kind of universal repelling force, to allow a static...
