WebOct 30, 2014 · These can be separated into two broad categories: quantum methods [11], which evaluate the wavefunctions at the level of individual electrons and are necessary when quantum effects become important (surprisingly, there are examples of this in macroscopic biological processes [12,13]), or classical methods, which go one step up … WebMaster equations II. 5.1 More on master equations 5.1.1 Birth and death processes An important class of master equations respond to the birth and death scheme. Let us assume that “particles” of a system can be in the state X or Y. For instance, we could think of a person who is either sane or ill. The rates of going from X to Y is !1 while
