Right to the start of the APS March meeting our paper appeared on arXiv. See: link

Jann Ungerer, Alessia Pally and collaborators have achieved strong coupling of a singlet-triplet qubit with a microwave photon. This work has now appeared in Nature Communications. They have employed crystal-face controlled nanowires that were grown at Lund university and provided

We are thrilled to share our new paper entitled “Charge-4e supercurrent in a two-dimensional InAs-Al superconductor-semiconductor heterostructure” by Carlo Ciaccia.  Supercurrent is carried by Cooper pairs having charge 2e. Accordingly, the second Josephson equation, which relates an AC supercurrent with

Congrats to Christian Jünger and Andreas Baumgarter: the paper entitled Intermediate states in Andreev bound state fusion is finally out in Comm. Physics. The paper makes use of the best quantum dots (QDs) known to us. These QDs are grown

Entanglement has been at the centre of the 2022 Noble Prize in physics: NoblePrize22. Today, optical sources that generate pairs of entangled photons can routinely be realized and used in, for example, secure data communication. In contrast, it has turned out

Yet another example of the high quality of h-BN dielectrics that have been engineered and provided by Kenji Watanabe and Takashi Taniguchi from the National Center for Materials Nanoarchitectonics, National Institute for Materials Science, 1-1 Namiki, 17 Tsukuba 305-0044, Japan.

Today, our paper on strained induced scalar potential in graphene appeared, see: publication. When graphene is uniaxially strained, the unit cell is elongated which leads to a chnage in the binding energy. This change has the same effect as an electrostatic

Mehdi Ramezani’s paper entitled Superconducting Contacts to a Monolayer Semiconductor just appeared today (24th of June 2021) in Nano Letters. See:  link-to-paper Schottky barriers in semiconductors usually prohibit achieving transparent enough contacts required to induce superconductivity in the semiconductor by the

Graphene, the first truly two-dimensional material isolated, is never perfectly flat. Even when it is sandwiched between other atomically flat crystals, it still slightly ripples. These out-of-plane corrugations, the deformation of the graphene layer into the third dimension, have profound
