Caldeira-Leggett Model - Two different approaches for an ohmic environement
Friday, April 4, 2014
Two different approaches of the well-known Caldeira Legget model will be presented and discussed. While one approach is widely investigated in litterature, the other one is the way I used to obtain the same master equation. It will be oulined how some usual approximation seems to be not strictly necessary.
