Thermodynamics

Researchers in China have demonstrated heat flowing from cold to hot in a quantum system, potentially requiring updates to the second law of thermodynamics. Using a molecule as qubits, the team manipulated quantum information to achieve this reversal. The finding highlights differences between classical and quantum physics.

Researchers at the University of Stuttgart have shown that the Carnot principle, a cornerstone of thermodynamics, does not fully hold for correlated particles at the atomic level. Their work reveals that quantum engines can surpass the traditional efficiency limit by harnessing quantum correlations. This discovery could pave the way for highly efficient nanoscale motors.
