Premelting and formation of ice due to Casimir-Lifshitz interactions: Impact of improved parameterization for materials

Yang Li, Kimball A. Milton, Iver Brevik +5

Recently, the premelting and formation of ice due to the Casimir-Lifshitz interaction, proposed in early 1990s by Elbaum and Schick [Phys. Rev. Lett. 66, 1713-1716 (1991)], have be…

Dispersion forces in inhomogeneous planarly layered media: A one-dimensional model for effective polarisabilities

Johannes Fiedler, Fabian Spallek, Priyadarshini Thiyam +4

Dispersion forces such as van der Waals forces between two microscopic particles, the Casimir--Polder forces between a particle and a macroscopic object or the Casimir force betwee…

Impact of effective polarisability models on the predicted release dynamics of CH and CO from premelted ice

J. Fiedler, P. Thiyam, F. A. Burger +6

We present a theory for Casimir--Polder forces acting on greenhouse gas molecules dissolved in a thin water film. Such a nanosized film has recently been predicted to arise on th s…

Distance-dependent sign-reversal in the Casimir-Lifshitz torque

Priyadarshini Thiyam, Prachi Parashar, K. V. Shajesh +5

The Casimir-Lifshitz torque between two biaxially polarizable anisotropic planar slabs is shown to exhibit a non-trivial sign-reversal in its rotational sense. The critical distanc…

Effective Polarisability Models

Johannes Fiedler, Priyadarshini Thiyam, Anurag Kurumbail +7

Theories for the effective polarisability of a small particle in a medium are presented using different levels of approximation: we consider the virtual cavity, real cavity and the…

Lifshitz interaction can promote ice growth at water-silica interfaces

Mathias Boström, Oleksandr I. Malyi, Prachi Parashar +6

At air-water interfaces, the Lifshitz interaction by itself does not promote ice growth. On the contrary, we find that the Lifshitz force promotes the growth of an ice film, up to…

The influence of Lifshitz forces and gas on premelting of ice within porous materials

M. Boström, O. I. Malyi, P. Thiyam +4

Premelting of ice within pores in earth materials is shown to depend on the presence of vapor layers. For thick vapor layers between ice and pore surfaces, a nanosized water sheet…

Anisotropic contribution to the van der Waals and the Casimir-Polder energies for CO and CH molecules near surfaces and thin films

Priyadarshini Thiyam, Prachi Parashar, K. V. Shajesh +7

In order to understand why carbon dioxide (CO) and methane (CH) molecules interact differently with surfaces, we investigate the Casimir-Polder energy of a linearly polariz…

Non-Perturbative Theory of Dispersion Interactions

M. Boström, P. Thiyam, C. Persson +4

Some open questions exist with fluctuation-induced forces between extended dipoles. Conventional intuition derives from large-separation perturbative approximations to dispersion f…

Non-Perturbative Theory for Dispersion Self-Energy of Atoms

Priyadarshini Thiyam, C. Persson, I. Brevik +2

We go beyond the approximate series-expansions used in the dispersion theory of finite size atoms. We demonstrate that a correct, and non-perturbative, theory dramatically alters t…

Intermolecular Casimir-Polder Forces in Water and near Surfaces

Priyadarshini Thiyam, Clas Persson, Bo E. Sernelius +3

The Casimir-Polder force is an important long range interaction involved in adsorption and desorption of molecules in fluids. We explore Casimir-Polder interactions between methane…

Finite size dependent dispersion potentials between atoms and ions dissolved in water

P. Thiyam, M. Boström, C. Persson +3

A non-expanded theory is used for dispersion potentials between atoms and ions dissolved in a medium. The first-order dispersion interaction between two atoms in an excited state m…
