Pure Quantum State Without Cooling Effort

➀ ETH Zurich researchers demonstrated a near-pure quantum state (92% quantum purity) in a nanoparticle tower at room temperature without cryogenic cooling;

➁ The experiment achieved suppression of classical motion, observing quantum fluctuations in an object containing hundreds of millions of atoms—a record in scale and purity for room-temperature systems;

➂ Potential applications include ultra-sensitive quantum sensors for dark matter detection, miniaturized medical imaging devices, and navigation systems independent of GPS satellites.

The Copenhagen Faust: The Birth of Quantum Mechanics

➀ The 1932 Copenhagen meeting marked a pivotal moment in the development of quantum mechanics, involving key figures like Niels Bohr, Paul Dirac, Werner Heisenberg, and Lise Meitner. ➁ Quantum mechanics emerged from collaborative efforts rather than individual contributions, unlike Einstein's theory of relativity. ➂ The Copenhagen interpretation of quantum mechanics, while revolutionary, was not universally accepted and faced ongoing debates among its creators. ➃ The personal lives and interactions of these physicists played a significant role in shaping the scientific discourse and their contributions to quantum theory.

New Method for Determining Exchange Energy in 2D Materials

1. Researchers from the University of Basel have developed a new method to measure the exchange energy in molybdenum disulfide, a 2D material. 2. This method involves exciting the material with a laser and analyzing the emitted spectral lines to determine the energy required to flip an electron spin. 3. The findings indicate that molybdenum disulfide exhibits highly stable ferromagnetism, similar to iron.
