A new study by Queen Mary University of London mathematician Professor Ginestra Bianconi proposes a new perspective on one of the deepest questions in modern physics: how can the Universe become increasingly structured and complex while still obeying the second law of thermodynamics? 

Theoretical physicists at Johannes Gutenberg University Mainz (JGU) have developed a new method of ordering Feynman integrals. This critical step in the scientific process of making theoretical predictions for high-energy precision measurements has posed a major computational bottleneck until now.

Quantum technologies promise revolutionary advances in computing, sensing, and information processing. However, controlling individual quantum bits (qubits) at the atomic scale remains a major challenge because conventional approaches rely on magnetic fields, which are difficult to confine to a single molecule.

A research team at the Center for Quantum Nanoscience (QNS) led by Director Andreas HEINRICH within the Institute for Basic Science (IBS), together with collaborators at Karlsruhe Institute of Technology (KIT), has now demonstrated that the quantum state of an individual magnetic molecule can instead be controlled electrically using a newly identified exchange-mediated mechanism. The study provides a new strategy for electrically controlling molecular quantum systems and could help pave the way toward more scalable quantum technologies.

Rare and endangered animals are often among the species most vulnerable to chemical pollution, yet scientists face a difficult problem when trying to assess those risks. Conventional toxicity experiments may require large numbers of organisms, making them impractical and ethically inappropriate for species with limited populations.

New study reveals that two widely studied ultrathin superconducting materials are more sophisticated than they appear. Although they seem to behave like simple superconductors with a single energy gap, they actually contain two strongly interacting superconducting states that work together and disguise themselves as one. This finding resolves a long-standing mystery about how these materials behave, providing new insight into superconductivity that could help scientists design better superconducting materials for future technologies such as quantum computers, ultra-efficient electronics, and advanced sensors.
