We explore thermodynamics of the apparent horizon in f(T) gravity with both equilibrium and non-equilibrium descriptions. We find the same dual equilibrium/non-equilibrium formulation for f(T) as for f(R) gravity. In particular, we show that the second law of thermodynamics can be satisfied for the universe with the same temperature outside and inside the apparent horizon.

Generalized second law of thermodynamics in f(T) gravity (2012, background): “Besides examining the validity of the thermodynamical interpretation of gravity by expressing the gravitational field equations into the first law of thermodynamics in different spacetimes, it is also of great interest to investigate the validity of the generalized second law (GSL) of thermodynamics”
f(T) teleparallel gravity and cosmology (2015, background): “In summary, in order for the second law of thermodynamics to be valid, from (366) we extract the requirement [282] Y ≡ − ( 4HT + Ṫ ) = 12H ( 2H(2) + Ḣ ) ≥ 0.”
