We study the efficiency of a quantum dot engine in the condition of the maximum power output. In contrast to the quasi-statically operated Carnot engine whose efficiency reaches the theoretical maximum, recent research on more realistic engines operated in finite time has revealed other classes of efficiency such as the Curzon-Ahlborn efficiency maximizing the power. The linear coefficient of...

In thermodynamics, there exists a conventional belief that “the Carnot efficiency is reachable only when a process is reversible.” However, there is no theorem proving that the Carnot efficiency is impossible in an irreversible process. Here, we show that the Carnot efficiency is attainable in an irreversible process through investigation of the Feynman-Smoluchowski ratchet (FSR). Thus, this...

We consider a classical open system in contact with heat bath via interaction Hamiltonian. We investigate two forms of energy transfer via the change of interaction Hamiltonian, which are interpreted as heats. One is heat dissipation from the system and the other is heat absorption by the heat bath, which are usually expected to be the same. Since the change of interaction Hamiltonian leads to...
86. Identification of spatial diffusivity patches by the wavelet processing of single-particle trajectories
Eugene Postnikov (Kursk State University)
Modern developments in single particle tracking not only open new perspectives for the study of molecular motions in complex environments, but also allow for using these motions as a probe for revealing properties of substrates on which the motions occur. This approach is especially important for studying biological membranes since their non-uniform structure (e.g. due to the presence of...
Zbigniew Grzywna (Silesian University of Technology, Faculty of Chemistry)
From a reach family of nonlinear diffusion equations the Burgers’ and Porous Medium equations have been chosen to demonstrate the possibility of getting their analytical solutions of some practically important IBVs problems. A comparison between numerical and analytical solutions have also been provided.
