Class resonantTwoLead#

Class Documentation#

class resonantTwoLead#

Resonant two-lead impurity model with charge conservation.

The model describes a single impurity site coupled to left and right leads, conserving total charge while allowing tunneling and local interaction terms.

Public Functions

inline resonantTwoLead(double teps, double tleftGamma, double trightGamma, double Uinterct)#

Construct the resonant two-lead impurity model.

Parameters:

  • teps – Onsite impurity energy.

  • tleftGamma – Left-lead tunneling amplitude.

  • trightGamma – Right-lead tunneling amplitude.

  • Uinterct – Local interaction parameter between the impurity occupancy and lead occupancy.
