If we can understand how and why light and matter behave as they do, we are one step closer to solving some of the most fundamental problems in physics. Finding the answers to these questions drives Ville Maisi, Associate Professor of Solid States Physics, Department of Physics. As long as he can remember he has been interested electric circuits and physics. With the support of a new ERC Consolida

By analysing high-resolution data from a 10-metre telescope in Hawaii, researchers in Lund, Sweden, have managed to gain new insights into three stars in the centre of the Milky Way. The stars turned out to be unusually young with a puzzling chemical composition that surprises the researchers. In the study, which is published in the scientific journal The Astrophysical Journal Letters, the Lund re

Down in the basement of the Department of Physics, the now world-famous short laser pulses are fired almost daily. This is home to Sweden’s cutting-edge research in attosecond physics. According to Per Eng-Johnsson, professor in atomic, molecular and optical physics, the research field is currently in the midst of a paradigm shift. The term “DIY” may appear to be an unlikely description of a high-

By utilising quantum mechanics, a quantum computer can solve computational problems that today's supercomputers cannot. But there are problems. As the circuits in quantum computers get bigger, they become more difficult to control. Now researchers have demonstrated a new way to construct quantum circuits for individual light particles. This could enable larger and more complex circuits - crucial t

Entanglement, once dismissed by Einstein as an impossible phenomenon but later shown to be possible by Nobel Prize-winning physicists, continues to raise questions. How can we know that a particle has been controlled? How can we know that the measurements of entanglement we think we are detecting are not in fact misleading due to inadequate detectors? In a new scientific paper, Armin Tavakoli demo

Astronomers can use supercomputers to simulate the formation of galaxies from the Big Bang 13.8 billion years ago to the present day. But there are a number of sources of error. An international research team, led by Lund University and Seoul National University, has spent hundreds of millions of computer hours over eight years trying to correct these. The last decade has seen major advances in co

What role does programming play in physics teaching? Can programming be used to teach physical concepts? In his dissertation, Kim Svensson examines how the movement between formula, code and visualisation can contribute to learning in physics. In the future, Kim hopes that programming can be used in a more open way, where students have the opportunity to explore their own models and ideas in a new

“If we succeed, this could be a method that helps find materials to build quantum computers that can withstand higher temperatures, with the possibility of fast operations,” says Mathieu Gisselbrecht. This is a quantum mechanical phenomenon that can best be described as an ensemble of particles for which the quantum state of each individual particle cannot be described independently of the state o
