Theoretical engines

Webb4 sep. 2024 · Theoretical studies on the efficiency of nanoscale devices usually employ rate (Pauli) equations, which do not account for quantum coherence. Therefore, the question whether quantum coherence could improve the efficiency of a molecular device cannot be fully addressed within such considerations. http://wallaceracing.com/calc-hp-bore-stroke.php
