Dependence of Tc on spin-amplified phonons in pressurized hydrides

[摘要] The realization of room temperature superconductivity in an under-high-pressure carbonaceous sulphur hydride has sparked off interest in pressurized superconductivity. The next and perhaps major hurdle is to achieve room temperature superconductivity (RTS) at ambient pressure. However, the quantum environment surrounding the pressurized RTS may give a glimpse of what is required to attain the phenomenon under normal pressure. This study is devoted to projecting the source of attraction of charges that keeps superconductivity afloat in hydrides under ultra-high pressure. Starting with the quantum equation of a normal-state ideal gas, we determine the dependence of Tc on pressure, spin and phonons. We show that plasmon mediation charges fails at ultra-high pressures. It is also found that bare phonons can sustain the mediation of charge pairing under pressure in the order of 1-100GPa but much less than the experimentally observe pressure, pcexp. However, the cooperation between spin and phonons sustains phonon mediation of charge pairing under much higher pressure pcexp. This is an indicator that the pairing of charges in pressurized superconductivity is mediated by enhanced phonons – spin-amplified phonons.
