Quantum heat dynamics toggled by magnetic fields

Researchers found dramatically enhanced heat oscillations in ZrTe₅ under strong magnetic fields and low temperatures, attributed to a novel mechanism involving electron-phonon interactions. This phenomenon is counterintuitive and has significant implications for understanding quantum transport in semimetals.

Discovering quasiparticles ejected from color centers in diamond crystals

Scientists have created extremely thin sheets of nitrogen-vacancy (NV) centers in diamond crystals, which exhibit exceptional sensitivity to environmental variations. The findings reveal the emergence of Fröhlich polarons, previously thought not to exist in diamonds, opening up new prospects for quantum sensing.
