    Matlab program for reaction diffusion system

    I'm trying to model a reaction-diffusion system on MATLAB and am struggling. I'm starting off with 4 particles on a lattice with 15 sites for ease, will take it to a larger scale when I've got the simple version down. the idea is to get randomly walking particles to eventually meet each other...

    Infinte sum - standard result?

    Hi, I'm working on a continuous time random walk problem, but my question is to do with analysis. I have and infinite sum and am unsure how to get form one step to the next or whether it is just a standard result. The variables aren't important but it looks like sum from n=0 to inf of...

    Graduate Explaining Continuous Time Random Walks: What Is It and How Is It Used?

    Hi, I'm trying to read into CTRW, but I'm finding the information online a little difficult to take in. From what I've read the process differs from normal random walks in that jumps take place after some waiting time \tau, which can be from 0<\tau<\infty. Would I also be right in saying that...

    Graduate Quantum optics, 2 qubit gates acting on 2 qubits - cannot be factorized?

    Quantum optics, 2 qubit gates acting on 2 qubits - cannot be factorized?? Hi, I'm struggling to understand why two qubit gates acting on two qubits cannot be factorized, i.e. G12 \neq G1 \otimes G2, where G1 acts on qubit 1 only and G2 acts on qubit 2 only.
