Emergent unconventional superconductivity in doped valence bond solid insulators

In this talk, I will discuss the unconventional superconductivity and non-Fermi liquid behavior in the doped valence bond solid insulators. Through sign-problem-free Quantum Monte Carlo simulation, we investigate the superconductor emergent from the doped valence bond solid insulators, which shares many properties with the superconductivity in doped resonance valence bond phases. Close to the valence bond solid quantum critical point, we observe the Non-Fermi liquid properties from the transport behavior. Our study sheds new light on Cooper pairing in the presence of strong Coulomb interaction. Moreover, this result might point to a new direction for searching high-Tc superconducting materials.
