Nonlinear Thermodynamic Analysis and Optimization of a Carnot Engine Cycle [PDF]
Entropy, 2016 As part of the efforts to unify the various branches of Irreversible Thermodynamics, the proposed work reconsiders the approach of the Carnot engine taking into account the finite physical dimensions (heat transfer conductances) and the finite speed of ...

Three-State Quantum Heat Engine Based on Carnot Cycle
Jurnal Fisika Unand, 2020 In this paper,we consider three models of quantum heat engines based on Carnot cycle using three energy levels; (1) the ground state, (2) the degenerate state, and (3) the highest energy state.

The thermodynamics of cognition: A mathematical treatment
Computational and Structural Biotechnology Journal, 2021 There is a general expectation that the laws of classical physics must apply to biology, particularly the neural system. The evoked cycle represents the brain's energy/information exchange with the physical environment through stimulus.

How the Brain Becomes the Mind: Can Thermodynamics Explain the Emergence and Nature of Emotions?
Entropy, 2022 The neural systems’ electric activities are fundamental for the phenomenology of consciousness. Sensory perception triggers an information/energy exchange with the environment, but the brain’s recurrent activations maintain a resting state with constant ...

What Is Psychological Spin? A Thermodynamic Framework for Emotions and Social Behavior
Psych, 2023 One of the most puzzling questions in neuroscience is the nature of emotions and their role in consciousness. The brain’s significant energy investment in maintaining the resting state indicates its essential role as the ground state of consciousness ...

Compatibility of Carnot efficiency with finite power in an underdamped Brownian Carnot cycle in small temperature-difference regime. [PDF]
Physical Review E, 2020 We study the possibility of achieving the Carnot efficiency in a finite-power underdamped Brownian Carnot cycle. Recently, it was reported that the Carnot efficiency is achievable in a general class of finite-power Carnot cycles in the vanishing limit of
