WebOur BCS-type model faithfully models the measured HHS which is shown to be sensitive to all quantum critical points. Our investigation provides a strong-field investigation of a high T c superconductor and measurement of its quantum phase transitions. The method clearly shows the efficacy to identify the different quantum phases, such as the ... WebWe present a systematic study of the dynamical phase diagram of a periodically driven BCS system as a function of drive strength and frequency. Three different driving mechanism are considered and compared: oscillating density of states, oscillating pairing interaction and oscillating external paring field. We identify the locus in parameter space …
