Summary
A diagram method to treat the Anderson model has been introduced. By applying this technique to the study of chemisorption phenomena, the density of states of adatom electrons has been calculated at finite temperature. Comparison with the results obtained in the symmetric limit at T=0 is given.
Riassunto
Un metodo diagrammatico è stato introdotto per studiare il modello di Anderson. Applicando questa tecnica al problema del chemisorbimento, è stata calcolata la densità degli stati elettronici localizzati a temperatura finita. È inoltre riportato un confronto con risultati ottenuti a T=0 nel limite simmetrico.
Резуме
Вводится диаграммный метод для рассмотрения модели Андерсона. Предложенная техника применяется для исследоваия явлений хемосорбции. При конечных температурах вычисляется плотность состояний электронов адатома. Проводится сравнение с результатами, полученными в симметричном пределе при T=0.
