Occupation-time statistics of a gas of interacting diffusing particles
Occupation-time statistics of a gas of interacting diffusing particles
The time that a diffusing particle spends in a certain region of space is known as the occupation time, or the residence time. Recently, the joint occupation-time statistics of an ensemble of noninteracting particles was addressed using the single-particle statistics. Here we employ the macroscopic fluctuation theory (MFT) to study …
