Periodic Reporting for period 1 - TOPOCOM (Topological solitons in ferroics for unconventional computing)
Période du rapport: 2023-09-01 au 2025-08-31
Recently, topological solitons in condensed matter moved into focus as promising nanoscale systems for unconventional computing. Topological solitons are particle-like textures that arise in ordered media. Such solitons are a rich source for emergent physical phenomena, enabling new pathways for low-energy information processing and data storage. Many of the developments in the field, however, occurred only in the past few years and it has become clear that we have only reached the tip of the iceberg concerning the topological solitons that form in electrically or magnetically ordered materials and their potential for applications.
TOPOCOM is a network of European experts assembled to provide enhanced training to 11 doctoral candidates (DCs) on the integrative concepts related to the physics of functional topological solitons and their application for unconventional computing. The DCs are trained at the cutting edge of science and technology and will come to appreciate the breadth of the field in terms of its intellectual challenges, commercial opportunities, and relationship to societal needs for ever more powerful information technologies with reduced environmental impact. This includes aspects of Green-IT, i.e. low-power technologies, one of the biggest challenges of modern society, as well as modern concepts for unconventional computing. The training enables the DCs to contribute to strengthening the European Research Area and the European Information and Communication Technology Industry in their future careers.
TOPOCOM’s ultimate goal is to move the field of unconventional computing the next level, driving essential advancements towards the realization of future soliton-based technologies.
Specific highlights were our TOPOCOM training workshops in Trondheim (Norway), Messina (Italy), and Heraklion (Greece), which covered both training through research (science & technology) and training for life (transferable skills). Here, the DCs learnt, for example, about fundamentals concerning electric and magnetic solitons, as well as materials synthesis and device applications, and they had various lectures given by experts about good scientific practice, intellectual property, academic publishing and more.
Scientifically, the TOPOCOM consortium made an important leap ahead and identified promising electric and magnetic model systems for unconventional computing. Protocols for material synthesis were developed, and we started to investigate the stability and dynamics of solitons in different materials, documented in internal reports to foster collaborations and exchange. Furthermore, we developed advanced tools to simulate electric and magnetic solitons, began to establish a universal mathematical framework, and performed first proof-of-concept experiments that demonstrate the general applicability of selected solitons for unconventional computing.
For example, our research shed new light on the importance of orbital transport mechanisms for the control of magnetic systems, the real time dynamics of topological defects, and the behavior of solitons in synthetic antiferromagnetic multilayers. Another highlight is a high-performance numerical solver that we developed for the simulation of polarization dynamics of topological solitons in ferroelectrics using CUDA/C/C++, using the Thrust library in CUDA, which provides flexibility and seamless switching between GPU and CPU for efficient parallel processing and data transfer.
In the next phase of the project, the DC training workshops will focus more aspects connected to devices for microelectronics and spintronics, making the step from fundamentals to devices, and “Boosting life after the PhD” will be at the core of our training for life activities, addressing topics such as project management, entrepreneurship, and investing in deep tech / founding of a company.
