Author(s): Fran Ivan Vrban, Antonio Šiber, and Primož Ziherl Within a model where micrometer-size soft colloidal particles are viewed as liquid drops, we theoretically study the contact interaction between them. We compute the exact deformation energy across a broad range of indentations and for various model parameters, and we show that it can be reproduced … [Phys. Rev.
