Active-Matter Battery
Yun-Qian Lin, Rui-Han Liu, Yu-Han Ma
Harnessing active matter to power functional devices has attracted growing interest. We propose a minimal battery model for storing energy extracted from active matter and derive i…
Finite-Time Thermodynamics of Battery Discharging: Power-Efficiency Trade-Off and Optimization
Rui-Han Liu, Yun-Qian Lin, Yu-Han Ma
Battery discharging is governed by a fundamental trade-off between output power and energy conversion efficiency due to internal dissipation. In this paper, we demonstrate that suc…
Finite-time Polytropic Steering Reveals Non-monotonic Irreversibility
Cong Fu, Youhui Lin, Shanhe Su +1
How irreversibility evolves from slow to fast driving is a central question in nonequilibrium thermodynamics. While near-equilibrium theory predicts increasing irreversibility with…
Unified approach to power-efficiency trade-off relations of generic thermal machines
Yu-Han Ma, Cong Fu
We present a general framework for determining the power-efficiency trade-off relations across arbitrary thermal machines, addressing the lack of unified optimization results stemm…
