Researchers at Chalmers University of Technology have for the first time succeeded in combining two major research fields in photonics by creating a nanoobject with unique optical qualities. Since the object is a thousand times thinner than the human hair, yet very powerful, the breakthrough has great potential in the development of efficient and compact nonlinear optical devices.

A research team led by Professor Monika Aidelsburger and Professor Immanuel Bloch from the LMU Faculty of Physics has investigated this question concerning quantum many-body systems and found indications that they can be described macroscopically through simple diffusion equations with random noise. The study was recently published in the journal Nature Physics.

Researchers from Skoltech, Universitat Politècnica de València, Institute of Spectroscopy of RAS, University of Warsaw, and University of Iceland have demonstrated the spontaneous formation and synchronization of multiple quantum vortices in optically excited semiconductor microcavities.

Although systems consisting of many interacting small particles can be highly complex and chaotic, some can nonetheless be described using simple theories. Does this also pertain to the world of quantum physics? A research team led by Professor Monika Aidelsburger and Professor Immanuel Bloch from the LMU Faculty of Physics investigated this question concerning quantum many-body systems and found indications that they can be described macroscopically through simple diffusion equations with random noise.

ICFO leads the first experimental demonstration of a deep subwavelength topological edge state within a nanophotonic system, a turnover in the field of topological Nanophotonics.

PQShield has designed and built the first fully functional post-quantum cryptography silicon test chip to support compliance of the new NIST PQC standards. According to the release, the test chip provides semiconductor vendors with the tools needed to implement secure PQC solutions as the industry shifts from preparation to meeting compliance requirements. This enables detailed evaluation of power usage, performance, and Side Channel Analysis (SCA) countermeasures, all in a real-world environment.

Scientists at EPFL, the Helmholtz-Zentrum Berlin and Freie Universität Berlin have uncovered intriguing insights into the magnetic properties of a complex material that dances on the edge of quantum spin liquid behavior. The discovery could have far-reaching implications for our understanding of quantum materials and their potential technological applications.

Moiré superlattices, structures that arise when two layers of two-dimensional (2D) materials are overlaid with a small twist angle, have been the focus of numerous physics studies. This is because they have recently been found to host novel fascinating unobserved physical phenomena and exotic phases of matter.

A method developed at the University of Bonn could have potential applications for tap-proof communication.

A research team led by Prof. YANG Kai at the Institute of Physics (IOP) of the Chinese Academy of Sciences, in collaboration with Prof. LADO Jose from Aalto University, has developed an important bottom-up approach to simulate quantum many-body topological phases at the atomic scale.
