Physicists use machine learning techniques to search for exotic-looking collisions that could indicate new physics
Posted by Saúl Morales Rodriguéz in categories: particle physics, robotics/AI
One of the main goals of the LHC experiments is to look for signs of new particles, which could explain many of the unsolved mysteries in physics. Often, searches for new physics are designed to look for one specific type of new particle at a time, using theoretical predictions as a guide. But what about searching for unpredicted—and unexpected—new particles?

Researchers tune Casimir force using magnetic fields
Posted by Saúl Morales Rodriguéz in category: physics
Research teams led by Prof. Zeng Changgan and Zhang Hui from the Hefei National Laboratory for Physical Sciences at the Microscale, the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences have achieved a reversible transition from the Casimir attraction to repulsion under magnetic field control by using a magnetic fluid as an intermediate medium. Their study is published in Nature Physics.
