We retrospect three abstract models for heat engines which include a classic abstract model
in textbook of thermal physics, a primary abstract model for finite-time heat engines, and a …

Shortcuts to isothermality are driving strategies to steer the system to its equilibrium states
within finite time, and enable evaluating the impact of a control promptly. Finding the optimal …

The finite-time dynamics, apart from its fundamental importance in nonequilibrium
thermodynamics, is of great significance in designing heat engine cycles. We build an …

We calculate analytically the stochastic thermodynamic properties of an isothermal
Brownian engine driven by a duo of time-periodic forces, including its Onsager coefficients …

The constraint relation for efficiency and power is crucial for the design of optimal heat
engines operating within finite time. We find a universal constraint between efficiency and …

We derive general relations between the maximum power, maximum efficiency, and
minimum dissipation regimes from linear irreversible thermodynamics. The relations simplify …

The Mpemba effect is a counterintuitive relaxation phenomenon whereby a system with a
higher initial temperature may cool down to the thermal state faster than an identical system …

Incorporating time into thermodynamics allows for addressing the tradeoff between
efficiency and power. A qubit engine serves as a toy model in order to study this tradeoff …

To optimize the performance of a heat engine in a finite-time cycle, it is important to
understand the finite-time effect of thermodynamic processes. Previously, we have shown …

We investigate maximum efficiency at a given power for low-dissipation heat engines. Close
to maximum power, the maximum gain in efficiency scales as a square root of relative loss in …
