Curzon Ahlborn Type Efficiency in a Brownian Heat Engine with Exponential Temperature Profile
Mesfin Asfaw Taye
We investigate a Brownian heat engine wherein a particle moves through a periodic ratchet potential under an exponentially decreasing temperature profile, a spatial configuration t…
Noise-Activated Dopant Dynamics in Two-Dimensional Thermal Landscapes with Localized Cold Spots
Mesfin Taye, Yoseph Abebe, Tibebe Birhanu +2
Controlling dopant transport with high spatial precision is crucial for improving the semiconductor functionality, reliability, and scalability. Although prior models of noise-assi…
A Unified Nonequilibrium Framework: Thermodynamic Distance, Dissipation, and Stationary Laws via Effective State Count, Variational Stationarity, and Thermodynamic Bounds
Mesfin Taye
We propose a variational framework for nonequilibrium thermodynamics built around the effective number of accessible state, a multiplicative count that ranges from for a uniform di…
Thermodynamic Irreversibility in Underdamped Brownian Motion with Spatial Temperature Gradients
Mesfin Taye
We analyze underdamped Brownian motion in non-isothermal media with quadratic, linear, and piecewise-constant temperature profiles. Exact identities for entropy production and entr…
A Universal Thermodynamic Inequality: Scaling Relations Between Current, Activity, and Entropy Production
Mesfin Taye
We derive a universal thermodynamic bound constraining directional transport in both discrete and continuous nonequilibrium systems. For continuous-time Markov jump processes and o…
Entropy Production and Thermodynamic Dynamics in Active and Passive Brownian Systems Driven by Time Dependent Forces and Temperatures
Mesfin Taye
In this work, we examine the impact of time-varying temperature and force on the thermodynamic features of active Brownian motor that moves with velocity against the force as well…
