Occupation-time statistics of a gas of interacting diffusing particles

T Agranov, PL Krapivsky, B Meerson - Physical Review E, 2019 - APS
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 …
