Preliminary prospects of a Carnot-battery based on a supercritical CO2 Brayton cycle

open access: greenActa Polytechnica, 2021
As a part of the change towards a higher usage of renewable energy sources, which naturally deliver the energy intermittently, the need for energy storage systems is increasing. For the compensation of the disturbance in power production due to inter-day

Continuity and boundary conditions in thermodynamics: From Carnot’s efficiency to efficiencies at maximum power

open access: yesEuropean Physical Journal: Special Topics, 2015
[...] By the beginning of the 20th century, the principles of thermodynamics were summarized into the so-called four laws, which were, as it turns out, definitive negative answers to the doomed quests for perpetual motion machines.

Construction and optimization of a quantum analog of the Carnot cycle [PDF]

open access: greenPhysical review. E, Statistical, nonlinear, and soft matter physics, 2015
The quantum analog of Carnot cycles in few-particle systems consists of two quantum adiabatic steps and two isothermal steps. This construction is formally justified by use of a minimum work principle.

Symmetry in thermal cycles and processes [PDF]

open access: yesiScience
Summary: Symmetry analysis is a cutting-edge research approach in physics, yet its application in macroscopic energy systems remains limited. This study demonstrates its potential to provide valuable insights for a deeper understanding and development of

Achieving Carnot efficiency in a finite-power Brownian Carnot cycle with arbitrary temperature difference. [PDF]

open access: yesPhysical 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?

open access: yesEntropy, 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]

open access: yesPhysical 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
