Diffusion of probability amplitudes
Let's say I have a probability amplitude $\psi:\Sigma\rightarrow\mathbb{C}$ for some domain $\Sigma$ (so, $\psi$ satisfies $\int_\Sigma |\psi|^2=1$). Is there a way to use $\psi$ as initial ...

direct conversion of heat to electric potential / current - are there theories that contradict the 'Kelvin Statement'?
In particular, William Thomson (Kelvin) appeared to be wrong about key things in physics (initially X-rays, aether, even aviation feasibility).

Randomly sampling a “well-mixed” solution of Brownian particles
I place $N$ Brownian particles in $V$ liters of solution, shake until I assume that the particles are "well-mixed", and sample and randomly sample an $S$ liter volume. What is the probability ...

What is the return probability for Brownian motion in three dimensions?
I would like to know the probability of return to the initial point in three dimensional Brownian motion. Does someone know an expression for the diffusion constant? (Suggestions of books on this ...

Is there an overlap between quantum dynamics and math of brownian motion?
Suppose you have dynamics of a coherent state. The state presents a normal distribution of finding the particle. Does anyone know of any attempts to connect modern advances in the probability theory ...

SDE for particle, PDE for the density
Given a particle on the plane we can assume that it follows 2D Brownian motion. On the other hand if there is a lot of such a Brownian particles one can be interested in the evolution of the density ...

What interpretive difference is there between defining a function with or without a differential as a postfactor?
I have thought about this and looked for answers for a long time now, but I do not have any name or label for this problem, which is the reason for the long title of this question.
I have come across ...

What does this observation of instantaneous velocity in Brownian particles mean?
I read this artice: Physicists Prove Einstein Wrong with Observation of Instantaneous Velocity in Brownian Particles
“We’ve now observed the instantaneous
velocity of a Brownian particle,” says
