- ZeroPi.t1_inductive(i=1, j=0, Q_ind=None, T=0.015, total=True, esys=None, get_rate=False, noise_op=None, branch_params=None)#
\(T_1\) due to inductive dissipation in a superinductor.

i (int >=0) – state index that along with j defines a transition (i->j)
j (int >=0) – state index that along with i defines a transition (i->j)
