    Hello.
    What is about the mean force which operates from the outside of the Casimir plates phenomenon?

    Thank you

    We investigate the nontrivial interplay between geometry and temperature in the Casimir effect for the sphere-plate and cylinder-plate configurations. At low temperature, the thermal contribution to the Casimir force is dominated by this interplay, implying that standard approximation techniques such as the PFA are inapplicable even in the limit of small surface separation. Thermal fluctuations on scales of the thermal wavelength lead to a delocalization of the thermal force density at low temperatures. As a consequence, the temperature dependence strongly differs from naive expectations. Most prominently, thermal forces can develop non-monotonic behavior below a critical temperature. We perform a comprehensive study of such geothermal phenomena in these Casimir geometries, using analytical and numerical worldline techniques for Dirichlet scalar fluctuations.

    Interesting. That is how I see time. Past pushes the future and future pulls the past

    There is nothing in the above to support this notion.

    You are wrong.

    And, the OP is confusing. What is it you're asking?

    Thank you for the article.
    I see I will have to devote more to this phenomenon.
