THEORETICAL DISCOVERY OF A NOVEL EMERGING SUPERCONDUCTING STATE
Due to the strongly interacting behavior, many-particle systems can show collective emerging phenomena. One such phenomena, the spin-charge separation is one of the most unusual manifestations of the concept of quasiparticles. By considering a quasiparticle as a bound state of a spinon and a roton, I investigate the effect of multi-channel interactions in a many-particle system. In addition to the conventional metal, Mott-insulator, and conventional superconducting phases, I find a novel emerging superconducting phase due to the spin-charge separation. This novel state is characterized by two broken U(1) global gauge symmetries associate with spinon and roton sectors of the system. This novel state can be differentiated from the conventional superconducting state by its non-zero quasiparticle weight. In this talk, I will discuss a potential model system to observe this novel emerging phase.
