About: Kinetic term

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

In physics, a kinetic term is the part of the Lagrangian that is bilinear in the fields (and for nonlinear sigma models, they are not even bilinear), and usually contains two derivatives with respect to time (or space); in the case of fermions, the kinetic term usually has one derivative only. The equation of motion derived from such a Lagrangian contains differential operators which are generated by the kinetic term. Unitarity requires kinetic terms to be positive. In mechanics, the kinetic term is * v * t * e

  • Em física, um termo cinético é a parte do Lagrangeano que é bilinear nos campos (e para os modelos de sigma não lineares, eles não são ainda bilinear), e geralmente contém duas derivadas em função do tempo (ou espaço); no caso dos férmions, o termo cinético geralmente tem apenas uma derivada. A equação de movimento derivada de tal Lagrangiano contém operadores diferenciais que são gerados pelo termo cinético. Na mecânica, o termo cinético é Na teoria quântica de campos, os termos cinéticos para campos escalares reais, campo eletromagnético e são (pt)
