In an unprecedented feat, physicists have crafted an engine reaching temperatures hotter than the core of the sun, opening a new window into the *strange world of quantum mechanics*. Unlike traditional engines that convert thermal energy into mechanical work, this insanely hot system operates at the microscopic scale, where classical physics breaks down and quantum effects reign supreme. Researchers observed unexpected fluctuations in energy flow and particle behavior, challenging long-held assumptions and revealing the counterintuitive nature of heat and work in quantum regimes.

Key findings include:

  • Quantum coherence impacting engine efficiency in unpredictable ways.
  • Observations of energy fluctuations that defy classical thermodynamics.
  • New insights into entropy production at extreme temperatures.
