Well-known examples include: high-temperature superconductivity in cuprates, Kondo effect in quantum impurity systems, spin-liquid in magnetic materials, strange metal non-Fermi liquid behaviors. The underling mechanism behind these phenomena is the strong electron correlations (Coulomb interactions), which leads to collective many-body phenomena. In this talk, I will introduce the basics of these phenomena and the theoretical approaches to account for these emergent quantum phenomena. In particular, I will focus on the mechanism of non-Fermi liquid &#8220;strange metal&#8221; phenomena in various rare-earth intermetallic compounds near magnetic phase transitions, characterized by quasi-linear-in-T resistivity and T-logarithmic specific heat coefficient at low temperatures [1][2][3]. We find competition between short-ranged anti-ferromagnetic spin-liquid state and the fluctuating Kondo correlations provide an excellent qualitative understanding of these strange metal states.<\/p>\n<p>[1] Strange metal state near a heavy-fermion quantum, Yung-Yeh Chang, Silke Paschen, Chung-Hou Chung*, critical point, Phys.
