Thermo-quantum diffusion in periodic potentials
R. Tsekov
Quantum Brownian motion in a periodic cosine potential is studied and a simple estimate of the tunneling effect is obtained in the frames of a quasi-equilibrium semiclassical appro…
Brownian motion and temperament of living cells
R. Tsekov, M. C. Lensen
The migration of living cells obeys usually the Einstein law of Brownian motion. While the latter is due to the thermal motion of surrounding matter, the cells locomotion is genera…
Quantum hydrodynamics of electron gases
Radomir Slavchov, Roumen Tsekov
Electron gases in metals are described as quantum charged Newtonian viscous fluids experiencing Ohmic Darcy friction on the solid lattice ions as well. The dispersion relation of t…
Bohmian mechanics versus Madelung quantum hydrodynamics
R. Tsekov
It is shown that the Bohmian mechanics and the Madelung quantum hydrodynamics are different theories and the latter is a better ontological interpretation of quantum mechanics. A n…
Dissipative time dependent density functional theory
R. Tsekov
The simplest density functional theory due to Thomas, Fermi, Dirac and Weizsacker is employed to describe the non-equilibrium thermodynamic evolution of an electron gas. The temper…
Dissipative and quantum mechanics
Roumen Tsekov
Three existing interpretations of quantum mechanics, given by Heisenberg, Bohm and Madelung, are examined to describe dissipative quantum systems as well. It is found that the Made…
