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.

Achieving Carnot efficiency in a finite-power Brownian Carnot cycle with arbitrary temperature difference. [PDF]
Physical Review E, 2021 Achieving the Carnot efficiency at finite power is a challenging problem in heat engines due to the trade-off relation between efficiency and power that holds for general heat engines.

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 ...

Maximum power and the corresponding efficiency for a Carnot-like thermoelectric cycle based on fluctuation theorem. [PDF]
Physical Review E, 2023 Here, we investigate the maximum power and efficiency of thermoelectric generators through devising a set of protocols for the isothermal and adiabatic processes of thermoelectricity to build a Carnot-like thermoelectric cycle, with the analysis based on

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

Limiting Performance of the Ejector Refrigeration Cycle with Pure Working Fluids
Entropy, 2023 An ejector refrigeration system is a promising heat-driven refrigeration technology for energy consumption. The ideal cycle of an ejector refrigeration cycle (ERC) is a compound cycle with an inverse Carnot cycle driven by a Carnot cycle. The coefficient
