Just earlier this month Debmalya’s and Annica’s work on how quasiparticle interference can be used as direct probe of odd-frequency superconductivity was published in Physical Review Letters, selected as an Editors’ Suggestion, see link. The results were further featured with Continue Reading …
We’re happy to announced that we have received funding for a Ph.D. student together with Jorge Cayao within the WISE project (Wallenberg Initiative Materials Science for Sustainability). The advertisement for the position is already out, for more information see Vacancies.
We’re extremely happy to have received five years of funding from the Swedish Research Council (Vetenskapsrådet, VR) in the form of a Consolidator Grant. For more information, see the University and Department news pages.
Last but not least, Oladunjoye Awoga also successfully defended his Ph.D. thesis this spring, making it three Ph.D. graduates in our group this year! On June 11th he defended his thesis “Studies of topological superconductors via defects” with Prof. Pascal Continue Reading …
On May 25th Tomas Löthman defended his Ph.D. thesis “Robust Platforms for Superconductivity: Disorder Robustness and Topological Density of States Peaks” with Prof. Carsten Honerkamp, RWTH Aachen as the opponent. The pandemic kept the lecture hall attendance down to Tomas and the chair with everyone Continue Reading …
Big congratulations to Johann Schmidt who very successfully defended his Ph.D. thesis “Topological superconductivity in multi orbital materials” on November 20th! Opponent was Prof. Karyn Le Hur from École Polytechnique. Due to the pandemic the lecture hall was almost empty, Continue Reading …
Congratulations to Suhas Nahas who successfully defended his Licentiate thesis (half-way Ph.D. thesis) on November 13th, with Prof. Carlo Canali, Linnaeus University as opponent.
We’re very happy to have received five more years of generous support from the Knut and Alice Wallenberg Foundation through a prolongation of the Wallenberg Academy Fellows grant. It’ll allow us to continue exploring new frontiers of topological quantum matter, Continue Reading …
We went to Krusenberg Herrgård and spent a nice and crisp fall day discussing future research plans and how to organize our work even better. Lots of good ideas and discussions!
We are very happy to have received a new large collaborative grant on “Dynamic Quantum Matter” funded for five years by the Knut and Alice Wallenberg Foundations together with Alexander Balatsky (Nordita), Jens Bardarson (KTH), Emil Bergholtz (Stockholm), and Stefano Continue Reading …
Read in our latest Phys. Rev. Lett. publication how differentiate between fake and true Majorana states in nanowire Josephson junctions, just by measuring the Josephson current. Also featured in a press release from the university, here in English and Swedish.
Annica spent the week teaching about odd-frequency superconductivity at the Nicolas Cabrera summer school outside Madrid.
On one of the last days of summer (?) we got together for a lunch BBQ. We had some delicious food, but most importantly, we said goodbye to two postdocs, wishing them the best of luck in their future very Continue Reading …
During August we’re organizing a 4-week program with an embedded 4-day conference: Topological Quantum Matter: From Low-Temperature Physics to Non-Equilibrium Dynamics together with Jens Bardarson (KTH), Emil Bergholtz (Stockholm), Jan Budich (TU Dresden), and Roni Ilan (Tel Aviv) at Nordita, Continue Reading …
We dropped our regular work for a day and went on a group hike to Lunsentorpet, a nice 10km forest hike outside Uppsala, for a picnic lunch and camp fire. Everyone had a great time: good company, nice weather and Continue Reading …
Spring has been quite busy as we’ve been giving talks and attending several conferences and workshops, including the Majorana and beyond workshop in Warsaw, the Bound states in superconductors workshop at MPI-PKS Dresden, the Strontium Ruthenate workshop at ETH Zürich, the Continue Reading …
Congratulations to Ola who successfully defended his Licentiate thesis today with Prof. Tomas Löfwander, Chalmers as the opponent!
We got together for a group dinner at a Lebanese restaurant for a good start on the new year.
Another Phys. Rev. B for the new year. This time on “Gap oscillations and Majorana bound states in magnetic chains on superconducting honeycomb lattices” published just now as Phys. Rev. B 99, 035127 (2019). This was the result of a Continue Reading …
It’s not exactly every day we have two articles published on the same day, but it happened today! Read about how impurities can detect non-trivial topology and how high-temperature cuprate superconductors can significantly enhance the temperature at which to find Continue Reading …
