Theory of Casimir Forces: A Unified Approach Using Finite-Temperature Field Theory
P. E. Brandyshev, Yu. A. Budkov
We present a quantum theory of Casimir forces between perfect electrical conductors, based on quantum electrodynamics and quantum statistical physics. This theory utilizes Kapusta'…
Osmolyte-Modulated Differential Capacitance and Disjoining Pressure for Nanoconfined Electrolytes: A Modified Poisson-Boltzmann Theory
Victoria A. Vasileva, Daria A. Mazur, Petr E. Brandyshev +1
This study employs modified Poisson-Boltzmann theory to systematically investigate the influence of zwitterionic osmolyte additives to an electrolyte solution on disjoining pressur…
A Fluctuation Theory of Liquid-Phase Solutions: Shear Viscosity
Yury A. Budkov, Nikolai N. Kalikin, Petr E. Brandyshev
Accurately describing liquids and their mixtures beyond equilibrium remains a significant challenge in modern chemical physics and physical chemistry, especially regarding the calc…
First-principle theory of the Casimir screening effect
Yu. A. Budkov, P. E. Brandyshev
In this paper, we use the formalism of finite-temperature quantum field theory to investigate the Casimir force between flat, ideally conductive surfaces containing confined, but m…
Thermomechanical Approach to Calculating Mechanical Stresses in Inhomogeneous Fluids and Its Applications to Ionic Fluids
Yu. A. Budkov, N. N. Kalikin, P. E. Brandyshev
This extended article presents a thermomechanical approach for calculating the stress tensor from the thermodynamic potential of inhomogeneous fluids and some applications to ionic…
