Zeeman operators package for Stoch Magnet module contains Zeeman classes.
Zeeman operators package for Stoch Magnet module contains Zeeman classes.
The Zeeman energy of a spin i is \( E^i_z= \mu_s (S_i,H^i_{ext}) \).
The zeeman magnetic field of the operator is \( H_z^i=H^i_{ext}\) which must verify the general relation \( H^i = - \frac{1}{\mu_s} \frac{\partial E}{\partial S_i} \)
The total Zeeman energy of the system is \( E_z=\displaystyle \sum_i E^i_z=-\sum_i \mu_s (S_i,H_{ext}^i)\)
The package contains the classes:
- SM_ZeemanOperator which is the generic class for which the applied field \(H_{ext} \) expressed in tesla is time and space dependant
- SM_ConstantZeemanOperator when the applied field is time and space independant
- SM_PermanentZeemanOperator when the applied field is time independand and space dependant
The UML organization of the package is:
