thanks you what references do you use

[@FuweiZhuge]

thanks a lot, quite clear explanations.

[@ivansudakov9703]

Could you, please, explain me why there is parabola in energy dependence ? U = (Ne)^2 /(2C) - NeV = (Ne - CV)^2/(2C) - (CV)^2/(2C). The last term does not depend on N but depends on CV. So when we are plotting the energy for different values of N as a function of CV, why the last term (CV)^2/(2C) is not considered ?

[@louisfry5920]

The parabolic dependence is due to the integration of the potential against charge, which gives charge squared. It is linked to the relation U = 1/2 * C * V^2.. The last term is not considered because it isn't important when considering *changes* in the free energy when N is changed. Since the probability of the tunneling events are controlled by this change, the N-independent term will be cancelled out: U(N) - U(N+1) for example..

Thank you very much :)

Which book have you followed for this Sir?

[@cerimite7674]

Could any excess energy in the capacitor be redirected for creating more majorana particles in a closed system.

nothing is understandable ..The coulomb diamonds ae no esplained well
