报告摘要:

Superconductivity and charge density waves (CDWs) are two fascinating quantum phenomena in solid-state materials, both typically linked to electron-phonon coupling. In this report, I will present our recent advances in the design of materials exhibiting these phenomena. First, we propose an effective multi-orbital strategy to suppress electronic instabilities and significant quantum fluctuations in quasi-one-dimensional (Q1D) superconductors. Using this strategy, we have designed a chain-like Q1D material, NaBe, which may exhibit a record-high Tc among all known Q1D superconductors. Second, we predict the emergence of charge density waves and Ising superconductivity in certain two-dimensional (2D) transition metal dichalcogenides (TMDCs), including HfTe2, TaSe2, and TaTe2. Our findings show that these properties can be effectively tuned by controlling the thickness and stacking order of the TMDC layers.
