Summary: | In this thesis, Lindblad Equation and decoherence phenomenon model in entangled
K-meson based on Lindblad Equation will be discussed. Before discussing it, some
theories needed are explained. Then, Lindblad Equation is derived from
microscopic dynamics and as a completely positive and trace-preserving (CPT)
generator. By using Lindblad Equation, dynamical equation of entangled K-meson
system that interact with the environment is obtained. From this dynamical
equation, parameters related to the decoherence of the system are determined. There
are two paramater determined, decoherence parameter (?) and effective
decoherence parameter (?). By using Standard Least-Squares method, the author of
this thesis obtained ?=0,13±0,865. This result correspond with reference result that
use effective variance method, ?=0,13-0,15
+0,16, which correspond with
?=(1,84-2,17
+2,50)×10-12 MeV. The value of these parameters are relatively small which
mean the information from the system is relatively maintained. |
