We derive the equations of motion for Palatini F(R) gravity by applying an entropy balance law
TdS = Q + N to the local Rindler wedge that can be constructed at each point of spacetime.
Unlike pre...

For a thermal field theory formulated in the grand canonical ensemble, the distribution of the
total momentum is an observable characterizing the thermal state. We show that its cumulants
are relate...
