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.
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.
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.

Abstract
Spin-orbit coupling (SOC) relates to the interaction between an electron’s motion and its spin and is ubiquitous in solid-state systems. Although the effect of SOC in normal-state phenomena has been extensively studied, its role in superconducting hybrid structures and devices elicits many unexplored questions.…

Abstract
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...
