Article Synopsis
- The superconductor-insulator transition (SIT) in two dimensions represents a key quantum phase transition with a quantum critical point at absolute zero temperature (T=0).
- In certain weakly disordered or crystalline thin films, an anomalous metallic (AM) state shows up between superconducting and insulating states, complicating the traditional QPT understanding of SIT.
- Measurements of the Nernst effect reveal a ghost-temperature line marking a thermal-to-quantum crossover, helping to locate the QCP within the AM state, thereby suggesting that the AM state is a critical extension of the SIT.
