C’est la reine des laines. Le cachemire. Mais l’afflux sur le marché mondial de pulls plus abordables a des conséquences sur tout un pays… Que font les marques pour limiter leur impact ?

Casimir Interaction between Polydisperse Colloids Trapped at a Fluid Interface
We investigate the effect of polydispersity on fluctuation-induced interactions between Janus colloidal particles trapped at a fluid interface. Using the scattering-matrix formalism, we calculate the thermal Casimir energy in both two- and three-body systems, considering three distinct fluctuation scenarios for the colloids: (a) fixed, (b) bobbing, and (c) bobbing and tilting. Our results reveal a pronounced sensitivity to polydispersity that strongly depends on the fluctuating boundary conditi…

An M-theory dS maximum from Casimir energies on Riemann-flat manifolds
We initiate the study of flux compactifications on non-supersymmetric Riemann-flat manifolds (RFM's) with Casimir energy. While curvature and other corrections are suppressed in RFM's, the inclusion of Casimir energies allows one to evade standard dS no-go theorems, and the absence of orientifolds or other singular sources means that the construction is completely captured by ten or eleven-dimensional supergravity. We obtain a fully explicit formula for the Casimir stress-energy in a general RF…

Nonclassical microwave radiation from the parametric dynamical Casimir effect in the reversed-dissipation regime of circuit optomechanics
We propose an experimentally feasible optomechanical system (OMS) that is dispersively driven and operates in the reversed dissipation regime (RDR), where the mechanical damping rate far exceeds the cavity decay rate. We demonstrate that coherent, fast-time modulation of the driving laser frequency-on time scales longer than the mechanical decoherence time-allows for adiabatic elimination of the mechanical mode, resulting in strong parametric amplification of quantum vacuum fluctuations of the …
