Impact of low-energy spin fluctuations on the strange metal in a cuprate superconductor

Schéma vu de profil et image microscopique vue de face de l’imbibition forcée d’un maillage hydrophobe. Atteindre la pression de passage mène à une situation a priori instable où la première goutte qui passe aspire toutes les autres (encadré en rouge). La présence d’une contrainte seuil apporte une stabilité et donc un passage homogène (encadré en vert) qui permet la coalescence des gouttes de fluide au-delà du maillage.

Understanding the mechanical response of foams by observing individual bubbles

Figure: A Brownian particle (subject to thermal agitation) wanders in a confined well until it reaches a threshold, where an automated system (a demon) acts on the position of the well to extract energy from the particle. The cyclical operation of the process creates a temporal information engine between the demon's actions.
