epraya.Qii#

Qii(iix, iiy, iiz, q, dim)#

Function for the nuclear quadrupolar interaction.

Parameters:

  • iix (np.array) – Pauli matrix of the nuclear spin x component.

  • iiy (np.array) – Pauli matrix of the nuclear spin y component.

  • iiz (np.array) – Pauli matrix of the nuclear spin z component.

  • q (np.array) – Array for the quadrupolar interaction constant.

  • dim (int) – Dimension of the total hamiltonian.

Returns:

tql (np.array) – Matrix of the nuclear quadrupolar interaction with dimension dim.

Example

>>> import epraya as epr
>>> Ham,Exp,_=epr.Start()
>>> Ham.I=1
>>> Ham.Q=[0.5,10.0,0]
>>> Ham=epr.chaframe(Ham,Exp)
>>> ix,iy,iz=epr.Pauli(Ham.I)
>>> dim=int((2*Ham.I+1))
>>> print(epr.Qii(ix,iy,iz,Ham.Q,dim))
