Abstract In this work, we study the influence of the surface on the energy of spin excitations of a ferromagnetic crystal in the Heisenberg model, with a particular focus on the possibility of using this effect to create planar metamaterials.

Sense Of Obligation

Abstract Tomasello offers a compelling account of the emergence of humans’ sense of obligation. We suggest that more needs to be said about the role of affect in the creation of obligations. We also argue that positive emotions such as gratitude evolved to encourage individuals to fulfill cooperative obligations without the negative quality that Tomasello proposes is inherent in obligations.
