چكيده فارسي :
A new type of symmetry in the large deviation function of a time-integrated current is introduced. This current is different from the
fluctuating entropy production for which the large deviation function is symmetric in the content of the fluctuation theorem. The
origin of this symmetry, similar to that of the Gallavotti-Cohen-Evans-Morriss symmetry, is related to time-reversal. The symmetry
is more unveiled when one performs an appropriate grouping of stochastic trajectories in the space of microscopic configurations. It
turns out that the characteristic polynomial of the modified generator of this current is not symmetric; however, its minimum
eigenvalue is symmetric.
