Extended chaotic junction. a, b Analytic results from GHD for \(\gamma =\pi /4\) in the energy-transport scenario for different values of the boundary resistance \(R\), as indicated in the legend; a energy profile; b energy current. The value \(R=0\) corresponds to a limiting situation where \(| {T}_{-}-{T}_{+}| \to 0\) but \(({T}_{-}-{T}_{+})/R\) is finite. The black line shows the numerical data for \(t=40\). c Cartoon of the setting where the two integrable Hamiltonians are joined via a chaotic Hamiltonian \({\hat{H}}_{\text{chaos}}\) on \(\ell\) sites
