Quantum computers are anticipated to solve certain computational tasks much faster than classical computers. In this talk, I will discuss the origins of quantum computing, explain the challenges involved in building a quantum computer, and explore their potential applications.
The fundamental building block of a quantum computer is the qubit, an individual quantum system that can exist in a...
Optical frequency combs are lasers whose spectra consist of hundreds of thousands of evenly spaced narrow lines spanning a broad spectral range. This unique combination of high spectral resolution and wide bandwidth has revolutionized molecular spectroscopy. Our group uses frequency combs to probe the energy level structure of molecules relevant to astrophysics, such as methane - the first...
In 2012 machine-learning tools achieved paradigm-shifting performance in image classification, but 2012 was also the year when the LHC collider at CERN discovered the Higgs boson. For the first time, a new fundamental particle was discovered with explicit use of machine learning tools. While until then machine learning was frowned upon as a valid tool by the physics community, in 2012 -almost...
Ultrafast cameras, using ultrashort light flashes, allow the capture of ultrafast motion. In atoms or molecules, attosecond light pulses are needed to capture the motion of electrons (1 as = 10$^{-18}$ s). This presentation will highlight the physics behind the generation and application of attosecond light pulses.
There are many ways to learn, and one of the more modern approaches is gamification. Erik Elfgren, Associate Professor of Energy Engineering and appointed Excellent Teacher at Luleå University of Technology, asks the question: Is it possible to game your way to a physics education? How can gamification be used to increase motivation and improve learning? What are its advantages and...
Li-ion batteries are dominating the market for high-performance batteries. However, so-called post-Li batteries in which Li is replaced by other charge carriers such as Na, K, Mg, Ca, Al and even Cl offer the potential for competitive energy densities, but being significantly more abundant. In this talk, I will give an overview over the advantages and also obstacles associated with post-Li...
We will in this talk describe and demonstrate the basic principles of traps with a discussion of similarities and difference between optical traps, acoustic traps and electro-magnetic traps. We will give examples of current research where traps are used, with trapping of antihydrogen as the most striking example. The presentation will also discuss various pedagogical suggestions on how traps...
