Microscopic theory of current-induced skyrmion transport and its application in disordered spin textures
Emil Östberg, Emil Viñas Boström, Claudio Verdozzi
Magnetic skyrmions hold great promise for realizing compact and stable memory devices that can be manipulated at very low energy costs via electronic current densities. In this wor…
Fractional-statistics-induced entanglement from Andreev-like tunneling
Gu Zhang, Pierre Glidic, Frederic Pierre +2
The role of anyonic statistics stands as a cornerstone in the landscape of topological quantum techniques. While recent years have brought forth encouraging and persuasive strides…
Josephson junction π-0 transition induced by orbital hybridization in a double quantum dot
Rousan Debbarma, Athanasios Tsintzis, Markus Aspegren +5
In this work, we manipulate the phase shift of a Josephson junction using a parallel double quantum dot (QD). By employing a superconducting quantum interference device, we determi…
Minimal quantum dot based Kitaev chain with only local superconducting proximity effect
William Samuelson, Viktor Svensson, Martin Leijnse
The possibility to engineer a Kitaev chain in quantum dots coupled via superconductors has recently emerged as a promising path toward topological superconductivity and possibly no…
Transport-based fusion that distinguishes between Majorana and Andreev bound states
Maximilian Nitsch, Rubén Seoane Souto, Stephanie Matern +1
It has proven difficult to distinguish between topological Majorana bound states and nontopological Andreev bound states and to measure the unique properties of the former. In this…
Dephasing in a crystal-phase defined double quantum dot charge qubit strongly coupled to a high-impedance resonator
Antti Ranni, Subhomoy Haldar, Harald Havir +8
Dephasing of a charge qubit is usually credited to charge noise in the environment. Here we show that charge noise may not be the limiting factor for the qubit coherence. To this e…
