报告摘要：

In this talk, we discuss recent experimental observations and theoretical insights into the fascinating properties of two-dimensional (2D) materials, focusing on MoTe2 monolayers and HTSC. Specifically, we investigate the emergence of a room temperature electron-hole liquid and its underlying theoretical framework based on Keldysh form of Coulomb interactions in 2D. To gain a deeper understanding, we explore the band structure and degeneracy of MoTe2 and its implications for many-body theory involving simple exciton-exciton and electron-hole interactions. Furthermore, we delve into the intriguing phenomenon of noisy I-V curves observed in low-density 2D electron gases, proposing a possible explanation through electron-hole-impurity clusters.
