Boundary Element Method or Boundary Integral Method Computational Aspects
I have to solve a Helmholtz equation inside a simply connected domain. I know that in general the boundary integral can be written as,
$$\phi(x)=\int_V G(x,x') \rho(x')\ d^3x'+\int_S \left[\phi(x')\n …

Runge Kutta Method for a Lindblad Equation
I am solving a Lindblad equation for a dissipative Harmonic Oscillator.
My Hamiltonian is time dependent,
My Lindblad Equation can be written as
\begin{equation}
\frac{d\rho}{dt}=\frac{[H(t),\rho]}{i …

Runge Kutta Method for a Lindblad Equation
Hi guys I found the answer. The answer is Magnus expansion method. My method is not a good approximation. The method that I described is valid only in a very very small interval of time. Hence the num …
