Abstract
We study the crossover between thermal and shot-noise power in a chaotic quantum dot in the presence of non-ideal contacts at finite temperature. The result explicitly demonstrates that the temperature affects the suppression-amplification effect present in the main quantum noise. In particular, the weak-localization contribution to the noise has an anomalous thermal behavior when one let the barriers vary, indicating the presence of a critical point related to a specific value of the tunneling barriers. We also show how to get to the opaque limit of the quantum dot at finite temperature.
