How to deal with the numerical stability of the dimension and polynomial order in the SDPB? [closed]
This might be a far shot question, but any comment are welcome.
I'm using David Simmons-Duffin, Walter Landry, and Vasiliy Dommes's SDPB (Semi-Definite Programming Bootstrap) package to find the ...

Asking advice for numerical implementation of Conservative Finite Difference Method for solving Gross-Pitaveskii equation
I am trying to numerically solve the Gross-Pitaevskii equation for an impurity coupled with a one-dimensional weakly-interacting bosonic bath, given by (in dimensionless units):
\begin{align}
i \frac{\...

Calculation of magnetic vector potential A in FEMM [closed]
I don't have too much physics background. In the software FEMM, I simulated a closed loop magnetic circuit, and defined two current boxes (current density is uniform by default) on the left. The ...
