In everyday life, continuously doing work on a system is found to heat it up. Rubbing your hands together warms them. Hammering a piece of metal makes it hot. Even without knowing the equations, we learn from experience: driving any system, whether by stirring, pressing, or striking, leads to a rise in the system's temperature. /news/2025-08-quantum-gas-physicists-body-dynamical.html Quantum 糖心视频ics Thu, 14 Aug 2025 14:00:16 EDT news674378821 The ability to move electron-hole pairs鈥攃alled excitons鈥攊n desired directions is important for generating electricity and creating fuels.
