title: Out-of-equilibrium heating of electron liquid: fermionic and bosonic temperatures.
abstract: We investigate out-of-the equilibrium properties of the electron liquid in a two-dimensional disordered superconductor subject to the electric bias and temperature gradient. We calculate kinetic coefficients and Nyquist noise, and find that they are characterized by distinct effective temperatures: Te, characterizing single-particle excitations, TCp, describing the Cooper pairs, and Teh, corresponding to electron-hole or dipole excitations. Varying the ratio between the electric j and thermal jth currents and boundary conditions one can heat different kinds of excitations tuning their corresponding temperatures. We propose the experiment to determine these effective temperatures.
