Our vision is to trigger a revolution in low-power information and communication technologies in an energy-efficient society.

QuSpin´s objective is to develop the basic science that uses quantum entities such as the electron spin as information carriers in radically different ways. We aim at groundbreaking basic research that is crucial to the  development of fast, high-capacity, material systems and tools for smaller and more power-efficient electronic devices.

QuSpin Objective and Goal

Our Energy Efficient Future

A motivation is the usage statistics behind Apple, Google, YouTube, Netflix, and data mining for Bitcoin, as a few examples of the staggering amounts of data transfer and storage capacity that is needed for these services. Followed by their continuously increasing energy consumption needs, new ways to handle this efficiently is a pressing matter.

The Electronic Spin

Quasi-particles can convey spin information with exceptional tiny energy losses, considering the dynamical evolution of the spin states for high-speed electronics. A supercurrent is a remarkable phenomenon where a current can flow in a supercurrent with no electrical resistance and no energy loss.

Topological Superconductivity Mediated by Skyrmionic Magnons

Phys. Rev. Lett. 130, 156002 – Published 13 April 2023. Mæland, Kristian and Sudbø, Asle.

Topological superconductors are associated with the appearance of Majorana bound states, with promising applications in topologically protected quantum computing. In this Letter, we study a system where a skyrmion crystal is interfaced with a normal metal. Through interfacial exchange coupling, spin fluctuations in the skyrmion crystal mediate an effective electron-electron interaction in the normal metal...

dc Josephson Effect in Altermagnets

Phys. Rev. Lett. 131, 076003 – Published 17 August 2023. Ali Ouassou, Jabir; Brataas Arne; Qaiumzadeh, Alireza; Linder, Jacob.

The ability of magnetic materials to modify superconductors is an active research area for possible applications in thermoelectricity, quantum sensing, and spintronics. We consider the fundamental properties of the Josephson effect in a class of magnetic materials that recently have attracted much attention: altermagnets...
