Geometric Formulation of Power-Efficiency Bounds in Carnot-like Engines
R. X. Zhai
We formulate the power-efficiency constraint of Carnot-like heat engines as a geometric optimization problem in the plane of normalized branch dissipations. In this plane, efficien…

Exact bound of power-efficiency trade-off in finite-time thermodynamic cycles
R. X. Zhai, Xin Yue, C. P. Sun
Power and efficiency are fundamental criteria for evaluating the performance of thermodynamic cycles. However, it is generally impossible to maximize both simultaneously. In partic…

Quantum Zeno Effect in Heisenberg Picture and Critical Measurement Time
Wu Wang, Ruo-Xun Zhai, C. P. Sun
Quantum Zeno effect is conventionally interpreted by the assumption of the wave-packet collapse, in which does not involve the duration of measurement. However, we predict duration…
