Swedish Research Council (VR) project grant
The Geresdi Lab is now supported by the Swedish Research Council (VR) by a four-year-long project grant starting in January 2021. We will investigate the interplay of nuclear spin ordering and Andreev bound state physics in semiconductor nanowires. This project builds on our expertise with hybrid superconductor nanodevices and on-chip nuclear demagnetization cooling. See the Chalmers press release.

Review article on Andreev and Majorana bound states in Nature Review Physics
This review article (see publication and ArXiv link) is a result of an international collaboration of theorists and experimentalist researchers, and provides a comprehensive coverage of the field of Andreev bound states as well as the concept and prerequisites of topological protection leading to Majorana bound states.

Rodrigo Lopez joins the group for his MSc research project
Rodrigo, who currently is on the quantum track of the joint KU Leuven - Chalmers Erasmus Mundus Nanoscience and Nanotechnology program, will carry out his masters project in our group. He will focus on the design and measurement of planar superconducting resonators tailored for Andreev quantum bits.

First dilution refrigerator is installed
The Geresdi Lab welcomes the first Bluefors LD400 dilution refrigerator after a busy week of installation and testing. With DC and microwave capabilities and a 7 mK base temperature, this setup will be instrumental for our research activities. The group decided to name our first two refrigerators Embla and Ask, after the first couple created by the gods in Nordic mythology. Ask will follow Embla shortly, and will be installed in September.

New publication: Monitoring a single superconducting spin in Nature Physics
A joint publication with the QLab group at Yale, QuTech in Delft and the Center for Quantum Devices in Copenhagen showcases a novel way to connect single spin physics and superconducting quantum circuits. Read the publication in Nature Physics or on ArXiv (open access).

Instrument building grant by Excellence Initiative Nano
We received an additional 750kSEK grant to build low-noise electronics for cryogenic experiments as part of the low temperature infrastructure at Chalmers. This grant was awarded by the Excellence Initiative Nano and allows this activity to run for a year.

Bekmurat Dalelkhan joins the lab as a postdoc
Bekmurat finished his PhD thesis on InSb nanowires last year at the Centre of Nanoscience and at the Department of Physics at the Lund University. His project involved growth and characterization of nanodevices built on semiconductor nanowires.

User access for the European Microkelvin Platform
Attila visits the group of prof. Dominik Zumbuhl at the Basel University for a joint nuclear demagnetization experiment funded by the European Microkelvin Platform. With this measurement, we will compare indium and copper as nuclear refrigerants for nanoelectronics in an effort to push the lowest electron temperatures well below 1 millikelvin (which is already very cold!).
