  • Dunkle Materie unter dunklen Tannen

    Die Uni Zürich ist jetzt dank Neuzugang Björn Penning Mitglied bei einem abenteuerlichen Dunkle-Materie-Experiment.

    Tief unter den Black Hills in den USA suchen Wissenschaftlerinnen und Wissenschaftler mit einem hochempfindlichen Detektor nach Dunkler Materie. Mit dabei ist seit Anfang des Jahres auch die Universität Zürich durch den Neuzugang Björn Penning. Damit ist Zürich an beiden führenden Dunkle-Materie-Experimenten beteiligt, und die Zukunft ist auch schon in Planung...

    Unter diesen Hügeln laufen mehrere Teilchenphysik-Experimente, die den Geheimnissen der dunklen Materie und der Neutrinos auf die Spur kommen sollen:

  • A novel quantum state in an elemental solid

    In collaboration with experimental researchers from Princeton University, the group of Titus Neupert unveiled a new topological state of an elemental arsenic. The work shows that arsenic is a “hybrid” topological material. As such, the 3D semiconductor has special conducting topological states on its surface, as well as a separate set of such states on the hinges of the crystal. Such states are envisioned to carry current at lowest dissipation in future electronic devices.

    Based on the findings of this study, arsenic joins in a family of isostructural elements bismuth and antimony, which, respectively, support hinge and surface states only. The results are published in Nature 628, pages 527–533 (2024) (

  • Quantum transport response of topological hinge modes

    Experimentalists from Princeton University, in collaboration with Titus Neupert, have found evidence for quantum coherent transport along the crystal hinges of a topological quantum material. The material in question is bismuth bromide, a so-called higher-order topological insulator. The theory group of Titus Neupert had predicted the existence of such materials in 2017, with various proposed material systems probed with different experimental techniques over the past years. The common feature of such higher-order topological insulators are conducting channels on the crystal hinges which are carrying current free of dissipation. As such, they could be used in future electronics.

    The present experiment, for the first time, demonstrates quantum coherent transport through such hinge modes, by demonstrating so-called Aharonov-Bohm oscillations of the conductivity in a magnetic field. While the experiment does not prove the dissipationless nature of current flow, it demonstrates that the current is clearly concentrated at the crystal hinges.

  • SHiP experiment approved

    Just over ten years after its initial proposal, the SHiP experiment has been approved by the CERN management to start data taking in the next decade! The SHiP experiment is designed to search for extremely weakly interacting particles by using an incredibly intense beam of protons available at the LHC.

    The experiment was co-founded by Prof. Nicola Serra and was supported by an SNF-Starting grant in the design phase, where Martina Ferrillo (left) and Dr. Iaroslava Bezshyiko (right) made vital contributions. The approval of the CERN management moves the experiment into the finalization of the design and construction phase – what an exciting time to be part of the experiment!

  • Wtt production

    Group Grazzini: Wtt production paper

    Congratulations: The paper on Wtt production has been published on PRL as Editors’ suggestion!

    The production of a top-antitop quark pair in association with a W boson (t¯tW) is one of the heaviest signatures currently probed at the Large Hadron Collider. Since the first observation reported in 2015, the corresponding rates have been found to be consistently higher than the standard model predictions, which are based on next-to-leading order calculations in the QCD and electroweak interactions. The paper present the first next-to-next-to-leading order QCD computation of t¯tW production at hadron colliders.
