Recently, researchers from the group of Prof. Xinliang Feng (TU Dresden, MPI Halle, Germany) in collaboration with the scientists from Switzerland, Portugal and Spain have succeeded in building carbon-based quantum spin chains, where they captured the emergence of one of the cornerstone models of quantum magnetism first proposed by the 2016 Nobel laureate F. D. M. Haldane in 1983. Published in the journal Nature, the results could have widespread implications in the understanding of low-dimensional quantum magnetism and may contribute toward the emerging field of quantum computation. more

Much effort is being made to develop new types of memory devices that can revolutionize the computing paradigm of the past half century. Major breakthroughs are needed, in particular, in the domain of Deep Learning as a subset of Artificial Intelligence. In-memory computing and brain inspired neuromorphic hardware are the driving principles for this paradigm shift. Recently, a team of scientists at the Max Planck Institute of Microstructure Physics, Halle (Saale), and SEMRON GmbH, Dresden, Germany, have successfully demonstrated a unique capacitive memory technology with unprecedented energy-efficiency. The technology can easily be implemented using conventional silicon manufacturing processes and systems, thereby paving the way to its rapid commercialization and adoption in many application domains. The results were published in Nature Electronics on October 11^th. more

Racetrack memory devices are novel spintronic memory-storage devices that have been demonstrated to have highly attractive properties, including high speed and density, and non-volatility. A novel feature of these devices is that the digital data is encoded as nanoscopic magnetic domain walls that are shifted to and thro along magnetic “racetracks” using current pulses. Recently, a team of scientists at the Max-Planck Institute of Microstructure Physics in Halle (Saale) have successfully realized the ionitronic manipulation of such current-induced domain wall motion in synthetic antiferromagnetic racetrack devices. The results have been published in the journal “Nature Communications”. more
