Thermodynamic uncertainty relations for many-body systems with fast jump rates and large occupancies — •Ohad Shpielberg¹ and Arnab Pal² — ¹University of Haifa, Haifa, Israel. — ²Department of Physics, Indian Institute of Technology, Kanpur, India

The thermodynamic uncertainty relations constitute an important inequality, bounding the entropy production through current fluctuations. The results have been successfully applied, in particular for single body dynamics. Here we present uncertainty relations and other useful inequalities for the many body systems, in the limit of highly occupied systems. The resulting coarse grained theory also accounts for tighter inequalities than the single body case.
