This inhomogeneity is mirrored by an apparent dimensional crossover in the paraconductivity measured in transport above the superconducting critical temperature Tc. This behavior was interpreted in terms of an anomalous diffusion of fluctuating Cooper pairs that display a quasiconfinement (i.e., a slowing down of their diffusive dynamics) on length scales shorter than the inhomogeneity identified by tunneling experiments. Here, we assume this anomalous diffusive behavior of fluctuating Cooper pairs and calculate the effect of these fluctuations on the electron density of states above Tc. We find that the density of states is substantially suppressed up to temperatures well above Tc. This behavior, which is closely reminiscent of a pseudogap, only arises from the anomalous diffusion of fluctuating Cooper pairs in the absence of stable preformed pairs, setting the stage for an intermediate behavior between the two common paradigms in the superconducting-insulator transition, namely, the localization of Cooper pairs (the so-called bosonic scenario) and the breaking of Cooper pairs into unpaired electrons due to strong disorder (the so-called fermionic scenario).","lang":"eng"}],"main_file_link":[{"url":"https://arxiv.org/abs/1907.13579","open_access":"1"}],"issue":"17","oa_version":"Preprint","quality_controlled":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"American Physical Society","title":"Effect of anomalous diffusion of fluctuating Cooper pairs on the density of states of superconducting NbN thin films","oa":1,"article_type":"original","date_created":"2019-12-22T23:00:41Z","date_updated":"2024-02-28T13:14:08Z","year":"2019","day":"25","_id":"7200","isi":1,"department":[{"_id":"MaSe"}],"article_number":"174518","month":"11","date_published":"2019-11-25T00:00:00Z","citation":{"chicago":"Brighi, Pietro, Marco Grilli, Brigitte Leridon, and Sergio Caprara. “Effect of Anomalous Diffusion of Fluctuating Cooper Pairs on the Density of States of Superconducting NbN Thin Films.” Physical Review B.

With the aid of this trial state we show that three different definitions of the ground-state energy of jellium coincide. In the first point of view the electrons are placed in a neutralizing uniform background. In the second definition there is no background but the electrons are submitted to the constraint that their density is constant, as is appropriate in density functional theory.
